Learn Java

Creating Login Page using Some of Javascript Framework

2022-05-30T12:43:00.010+07:00

Introduction

status : inprogress

So this writing intent to create notes for myself or other that looking to learn about frontend javascript framework. Also to utilize this frontend I'm gonna use some popular stylesheet.

This writing also meant to make me re-learn again if I didn't touch any of frontend job.

With so many framework out there I will try to use the popular first then do the rest. ReactJS, VueJS, and Angular is a must with Bootstrap, Material, and Tailwind.

I will also going to explore some of mobile code in React Native and Flutter.

I have to find a good css/stylesheet to be use in the code. so it will make comparing code much more simple.

ReactJS

for reactjs you can always start from their main site

https://reactjs.org/docs/getting-started.html
or more advanced, maybe simplified https://create-react-app.dev/docs/getting-started
learn from existing project on github or just go to https://reactjsexample.com/
see free sample from creative-tim https://www.creative-tim.com/templates/react-free. they also have github page so it would be good learning material
don't forget to learn testing with jest as the main site said https://reactjs.org/docs/testing.html
play around in stackblitz or other that can host code along with result

Advanced Reactjs

Trying IBM Cloud Foundry with Go

2021-04-15T20:57:00.003+07:00

Pre~

So sometime ago I try to search free host for Go and found out that IBM Cloud gave free stuff on their system. I went and try but didn’t read the document too much, I’m just excited to try the GO server. I’ve been learning the buffalo framework for a while then I have to stop because got injured in my ankle and try to rehabilitate them for a few month so I can walk again.

Anyway I found free stuff from IBM then I just want to try it out. This writing is just a documentation for me and anyone who see it useful. I didn’t try to write a very detailed or well edited science stuff. This document was meant to be a small cheatsheet for future reference.

IBM CLOUD DASHBOARD

If you already registered and logged in, you should be redirected to the Dashboard. If you see the menu from image below you’ll notice there are a lot of stuff ready to be explored. Now I just need to find where I could upload my GO code into server.

Anyway I chose the Cloud Foundry just because its on the very first menu and lucky for me its said “Deploy and run your applications without managing servers or clusters with IBM Cloud Foundry” and when scroll bit further I found that it has a lot of App runtime

and if you click .go it will redirect to Create Sample App page

note: I really should save the summary because it will be used for ibm cloud CLI

after creating the Free Cloud Foundry Service we can begin to upload the code. But before we could do that I suggest to read and try the Getting Started Part from the menu and try out IBM CLOUD CLI and using the sample code as base before we try our code. As you see in image below

IBM cloud host the sample code to use in Cloud Foundry. And if you see the sample code, the structure will be very different in what you and I use if we do from the website GO itself. The module path, and other stuff that I still don’t get it but I think IBM has own setting to be used for running GO. The framework that being used is GIN.

I already create using sample code. Here is the running site https://riza-go-pilot.us-south.cf.appdomain.cloud/

below is just unfinished writing and some screenshot. There are few error and deprecated code from the Getting Started doc, but I manage to run it.

Post~

I didn't put any detail just because I had so many error and don't care about anything else but how to troubleshoot this problem. Anyway thanks

IBM CLOUD CLI

1. ibmcloud

2. ibmcloud login, Target region, ibmcloud info

3. Error Using Target –cf

4. Installing ibmcloud cf

5. after found out what to input for empty org, space, api endpoint

6. using ibmcloud target –cf without error

7. Testing cloud foundry GO sample, and error

8. push the sample to Target, found out buildpack was deprecated

9. after few minutes its start

10. check result. And what a journey

Learning GO, Buffalo Web Framework

2020-10-20T15:06:00.006+07:00

LEARNING BUFFALO

MY ADVENTURE IN GOLANG

Intro

After finishing a fun and simple way creating hello world in GO, I decided to extend the learning adventure into web framework. My choice is Buffalo, because some web recommended me to do so. I will try other framework as well but that is for later writing. My plan in this will be

1. Setting Environment. I think it’s already set

2. Install Buffalo. Based on https://gobuffalo.io/en/docs/getting-started/installation. Install scoop check, Install buffalo check.

3. Follow The Document. From here https://gobuffalo.io/en/docs/getting-started/new-project

Follow The Document

Based on https://gobuffalo.io/en/docs/getting-started/new-project I will begin my own adventure. I hope I found a new error.

So it says I have to create my new application on my GOPATH

I will not do that. I’m going to create in another folder. And I found some error

as usual I just copy paste the error message with keyword golang. And stackoverflow answer with

let’s go install the thing. And see if it resolve.

After restarting visual studio code, and the messages says successfully built. I guess it’s resolve.

Next to do is start the app. I did “$ buffalo dev” But again bump into error. Well the document said “Generate project” so generate is done. But it says the app need database if you look into error messages

the getting started didn’t said anything about database and database configuration. So I just go into the files and found out that Readme.md said something about the database.

I think this one at Readme.md should be mention in the Getting Started document https://gobuffalo.io/en/docs/getting-started/new-project and place it before running the app. After looking into the doc, it is said that I have to look into Database section before running the app.

I guess I need to read better. Well anyway this one is screencap from Readme.md

You’ll need a postgres as default database, and edit the configuration in database.yml file, don’t forget to comment out test and production.

After that you can go start the $ buffalo pop create -a command. It will automatically create the database.

Then you can run $ buffalo dev as Readme.md mention it. If it’s work fine, you can view it in browser

go to http://localhost:3000/ and if you see this, then it’s working.

Reading Database Section

After this I decided to read the Database section https://gobuffalo.io/en/docs/db/getting-started/ it’s a quite heavy reading, but if you are already familiar with other programming languages like Nodejs this should be easier to understand. If you just started coding and your choice is Go then you don’t have to read all of this in one go, just comeback when you need an information. For example, usually I read the first one and then I’ll try it without finishing the whole article. And after few days I’ll encounter relationship or migration or something else related to database but I don’t know how the correct Go approach, then I’ll read some more. I think that it’s important to try it at least once before continuing to read.

Reading Routing Section

Again if you already experienced in ExpressJS you’ll catch up quick, but it always nice to read it once. https://gobuffalo.io/en/docs/routing/

Reading Action Section

Umm yeah good read. https://gobuffalo.io/en/docs/actions/ have a good tools to generate the files and code at the same time.

Reading Resources Section

This one section is very interesting for me. It generate CRUD for a table in one go along with the needed view. If you look into the code, it show a standard CRUD operation.

But what if we got a relation with another table? Apparently if you read at https://gobuffalo.io/en/docs/resources/#nesting-resources section it covers the question.

Reading Context Section

I don’t understand this one. https://gobuffalo.io/en/docs/context/

Reading Request Binding

https://gobuffalo.io/en/docs/bind/. So model can bind into form or json/xml

Reading Middleware

Again it’s good read, and of course I will use already existing middleware rather than create my own.

Reading The rest of Request Handling Section

Session and cookies, I think this one still the same as other programming language.

Conclusion from Reading a few article

Are this reading can make you a website with GO ? Yes, a simple one. Without Authentication and Authorization.

So what to do if I want to make a website complete with Authentication and Authorization also User Management with Role based Access ? Of course you need to google more.

Finding a Complete Website

My complete website is a website that have User Management module with Role Based Access and a good Authentication and Authorization middleware.

So how are we gonna achieve this ? Like I said before we need to google more. And with google more I found this article https://blog.john-pfeiffer.com/golang-buffalo-tutorial-to-create-a-web-site-with-authentication. It explain to use minimal Authentication and Authorization. But I can’t seem to find Role based one.

So let’s start making one. For a little bit of design in RBAC you can read these article https://elang2.github.io/myblog/posts/2018-09-29-Role-Based-Access-Control-MicroServices.html

, but for a starter I think I just need to create a simple one. For the first try, I gonna do a simple User Auth then moving to User management, then add the simple Roles Based Access.

I found some tutorial in creating buffalo with JWT its here https://www.littlewire.dev/2020/03/buffalo-auth/

Creating a simple User Authentication and Authorization

I create this based on article from littlewire https://www.littlewire.dev/2020/03/buffalo-auth/ and if you also look into https://github.com/gobuffalo/authrecipe the code almost the same, anyway so let’s jump into it. Before this I already create the coke app using $ buffalo new coke, without the –api like the article tells you.

Following Article

Up to User Action section everything works fine, until I tested Create User and found error which said “no transaction found” as you can see below. Maybe because the buffalo version is not the same or the imported library is different.

So I delete everything and try “$ buffalo generate resource users email password” and testing it again. It works fine.

So next thing to do should be override Validate and BeforeCreate.

This is the result

 // before create  
 func (u *User) BeforeCreate(tx *pop.Connection) error {  
      hash, err := bcrypt.GenerateFromPassword([]byte(u.Password), bcrypt.DefaultCost)  
      if err != nil {  
           return errors.WithStack(err)  
      }  
      u.Password = string(hash)  
      return nil  
 }  
 // Validate gets run every time you call a "pop.Validate*" (pop.ValidateAndSave, pop.ValidateAndCreate, pop.ValidateAndUpdate) method.  
 // This method is not required and may be deleted.  
 func (u *User) Validate(tx *pop.Connection) (*validate.Errors, error) {  
      var err error  
      return validate.Validate(  
           &validators.StringIsPresent{Field: u.Email, Name: "Email"},  
           &validators.StringIsPresent{Field: u.Password, Name: "Password"},  
           &validators.FuncValidator{  
                Field:  u.Email,  
                Name:  "Email",  
                Message: "%s is already taken",  
                Fn: func() bool {  
                     var b bool  
                     q := tx.Where("email = ?", u.Email)  
                     if u.ID != uuid.Nil {  
                          q = q.Where("id != ?", u.ID)  
                     }  
                     b, err = q.Exists(u)  
                     if err != nil {  
                          return false  
                     }  
                     return !b  
                },  
           },  
      ), nil  
 }

Anyway now I understand that the code from litewire maybe have different version then the one I’m using. I’m just gonna restart everything again and I hope I found what went wrong from my code.

It's not done yet. my aim is to make web service with Authorization, Authentication, User Management, maybe Role Base Accsess

Learning GO : Basic

2020-10-19T18:29:00.007+07:00

LEARNING GO

It’s My Learning Adventure

Intro

First of all I don’t have any experience in programming language called GO . I just notice it this month when I went to search for jobs online. There are a lot of company needed the experienced GO coder.

So this will be my own way learning GO. It’s not a tutorial but my own experience in learning a new things and hopefully this writing will be useful somewhere in the future.

Anyway I have experienced NodeJS and Pyhton so I don’t think this will be that hard.

Learning Plan

The learning method that I will use is...wait is there is any learning method ?. Anyway I just write what I usually do. So these are the plan on mastering GO.

1. Finding Resources

2. Setting up Environment

3. Start Coding

4. Find Web Framework in GO. Because that’s what I found in search for jobs

4.1 CRUD creation

4.2 Authorization and Authentication

4.3 User Management

5. Try to Host the web app. It’s free on IBM cloud https://cloud.ibm.com/

6. ….. I don’t know any. Maybe I post later.

1. Finding Resources

1. https://golang.org/ absolutely the basic. Read the Doc

2. Going search keyword : go web framework best. It seems there are a lot of them.

3. Going Github : https://github.com/avelino/awesome-go. There are a lot of them going open source.

I add later if I found one

2. Setting Up Environment locally

To start every coding journey always go for the original document. let’s visit https://golang.org/doc/ and start reading and reviewing.

2.1 Installing Go

There no difficult process in here. Just download and install. There is a link if you want to install different version https://golang.org/doc/manage-install.html. Its nice to have option, I’m using windows btw.

2.2 Review for Tutorial: Get started with Go

After coding a bit in Visual Studio Code, The IDE starting to install few tools to add. But found error. It didn’t found asm. The problem occurred when the IDE try to instal tools but got rejected by my Antivirus. So I have to exclude the Go Installation directory from my Antivirus.

It’s been 5 minutes, and I didn’t found any solution so going to repair the installation. After repair installation the all tools are installed perfectly without error

that was a good thing we found an error, so lucky me.

Following the Hello World.

Hello.go file work just fine.

Review for Call code in an external package

This one also work fine, and the description for installing other modules is quite interesting.

2.3 Review for Tutorial: Create a Go module

2.3.1 Creating Module that other can use

Creating Module works fine

2.3.2 Call Module

After executing go build found some error

search from google I found that it’s a new issue

I didn’t know everyone having the same problem.

But luckily someone already have the answer

so you should put hello directory outside greeting directory so its at the same level. Thank you good sir.

I found out that I miss these part I guess. When I look again in tutorial, it really says go up from greetings directory

after this the other tutorial works fine.

2.3.3 Review for Compile and install the application

This part is very interesting for me, so I can install the application as part of OS. And yeah I just noticed this now.

2.4 Basic Tutorial Done

With this I officially can use Go, and also enter the basic zone as Go Programmer. Next I will try the web framework. Since there are a lot of framework. I will start with something popular. Thank you if you are reading this. I think it will not add to your knowledge if you already have a Go Project on your hands but thanks anyway.

My SAMPLE CASES FOR ODOO

2020-08-18T02:46:00.004+07:00

My SAMPLE CASES FOR ODOO

VERSION 0.0.1 (18-aug-2020)

Introduction

Odoo is an ERP application but can be used for small business to medium business for free. I want to create a sample or maybe assumption when small business is using Odoo.

Right now (18 Aug 2020) I don’t know anything on how to use Odoo for e-Commerce business or maybe a Kiosk, small Cafe or even a retail store.

I know how to code python, I learn how to use python in Odoo framework, also I can create Custom Modules. But on how to use them, it’s still a grey area or even no colors. So this document will be a step for myself how to use Odoo in most cases and business, of course I’m only use the open source one.

I’m not an Odoo partner or work for Odoo. So this is not a sales promotion for Odoo. Just simply want to know how Odoo meant to be use.

This writing also meant to be use for my own learning document or even cheat sheet. To better understanding or to be better at using Odoo.

You can watch trailer for what Odoo can do at Odoo web site of course. https://www.odoo.com/page/tour

For starter let’s just dive in few google search. In hope maybe someone have a good understanding or already have running business or even just about to start with Odoo.

Keywords : odoo sample case.

Many cases can be read here https://www.willdooit.com/page/case-studies but it’s only overview on what are the problem and what solution Odoo will give.

Keywords : using Odoo

not much can be found. Only video from Odoo webinar. This one is How to manage a retail Company https://www.youtube.com/watch?v=3gYOJV6bDbQ they using Odoo free trial that is the Pro one. Not the Open Source one

This one talk about Develop app with Odoo Framework https://www.youtube.com/watch?v=rcuDKI6Hewk

this one talk about basic Odoo 8 for your business https://www.youtube.com/watch?v=nmvZH2BVQH0 they also sell Odoo class for a price. Wow $99 that’s really some pricey learning video.

So I guess everything already being upload or wrote or even used in video for Odoo. They done it in few webinar check it out https://www.youtube.com/user/openERPonline.

Then this writing will be creating sample cases based on real world or just based on assumption. I still don’t know where to start but I’ll be using Odoo video as base learning method and work it on my real world problem I guess. Many have been used for medium to large company but I still don’t know if its applicable for smaller business.

Maybe I start with kiosk or a simple web store, maybe a shoe retailer or an online food delivery company. Anyway I have not decided yet.

I’m going to end my writing for now. I will update this soon. After few trial with some of cases.

**Update

I found several case with challenge, problem, solution and success story with just few Google keywords. I'm using "odoo use case" on search engine and found some that maybe you might want to take a look

https://www.willdooit.com/page/case-studies
This web site tell their experience when Integrating Odoo with some existing System.

https://www.featuredcustomers.com/vendor/odoo/case-studies

This is the main case studies from Odoo itself.

I don't think they publish on how they do it. All of this just a trailer. I'm sure they have a lot of meeting and customization happened. The hardest part would be on how to handle the user to commit in learning and using new Application.

Check out my tutorial or cheat sheet for Module development in Odoo https://javalearning-adventure.blogspot.com/2020/07/learning-odoo-module-development.html

LEARNING SSIS

2020-08-04T15:30:00.004+07:00

LEARNING SSIS

RESOURCES, COURSES, TRAINING AND CHEAT SHEET

1 Introduction

This document intended for learning about SSIS. Learning resources, link to document and also cheatsheet for project based on SSIS.

I don’t know where I should obtain about courses and training, maybe I need to create it myself for further use.

2 Installation

I did the installation earlier but I forgot the step. With Visual Studio 2019 installation wizard you can get SSIS. I think it also need to install some tools.

3 Learning process and resources

You need to do a lot of reading to understand this tools, and also a lot of practice. But first we need to read the documentation for microsoft web site.

I found tutorial for SSIS in microsoft websites

https://docs.microsoft.com/en-us/sql/integration-services/integration-services-tutorials?view=sql-server-ver15

also on other website, this one contain so many tutorial check them out

https://www.tutorialgateway.org/ssis/

I think its better to learn from microsoft websites because its cover every basic thing, except handling error.

first try (SSIS, flat file, postgreSQL )

I did the tutorial first with flat file and postgreSQL it turn out that even if we can connect to postgre using ODBC the driver can’t detect meta data information from database. After that I try using sql rather than auto detect the table from database. It works. We can connect and get data from ODBC with sql command.

After that we move to using lookup data. I try to connect look up to postgre but it turnout only OLEDB connection being provide by SSIS so I guess we can’t use ODBC. There is using cache connection but I don’t know how to use it. So I give up there. Also there is option using free trial plugin from devart to make everything works. Since it’s not open source or free I gave up again.

This happened when I try to use ODBC and load table using preview

but it works fie if I use sql

but it’s different with ODBC destination tools, because ODBC destinantion tools didn’t have sql field to get data for mapping purpose.

I have look it up on google and also stack overflow. It have answer but I did not know how to implement it. Here is the link

https://stackoverflow.com/questions/49978007/unable-to-select-odbc-source-in-ssis-lookup

For the next trial and error I will use SQL SERVER Express that free from microsoft.

Learning Odoo 13 Module Development and Review

2020-07-18T08:44:00.009+07:00

USING ODOO 13

Introduction

This writing supposed to be a cheat sheet for helping myself to learn about Odoo, Odoo Development and also anyone who want to read this.

Odoo already have a good documentation in their websites you can check it here https://www.odoo.com/documentation/13.0/

What you need

Odoo source

you can get the source from odoo.com or github

https://www.odoo.com/page/download or https://github.com/odoo/odoo. Right now I'm using the https://www.odoo.com/page/download . I did using the github twice so I'm already familiar with it but now i want to explore something new and maybe we will find something.
Python v3.6++ (intermediate level).

https://www.python.org/downloads/windows/

You can learn some basic “web development with python” first if you still new at programming. Search with google.
Postgresql https://www.postgresql.org/download/

I’m using win Os for development and Visual Studio Code for IDE

What should you read first

Installation procedure from documentation

https://www.odoo.com/documentation/13.0/setup/install.html#setup-install-source
Module development from documentation

https://www.odoo.com/documentation/13.0/howtos/backend.html

1. Installation

This is just a review from the document and few adjustment to my environment. Also maybe a cheat sheet for personal use.

Next should be the installation cheat sheet.

Create directory for this practice or project. I create a directory called odoo_practice. And put the source code here.
Install python and set virtual environment. Then install dependency library from requirements.txt
Install postgres. Add postgres\<ver>\bin to PATH. Create new user with privilege to CAN LOGIN and CREATE DATABASE. Don’t use default user postgres
for windows download build tools for visual studio

1.1 Create Directory and put Source Codes

I have create odoo_practice directory to put the source code.

Next should be the directory structure from the source code.

1.2 Set Up Python Development Environment

Make sure python is ready on system environment. You can do this by opening command prompt and type python. Create python environment using.
python -m venv <name_of_your_environment>

I learn to create python environment from https://www.django-rest-framework.org/tutorial/quickstart/ or you can always google it.
I need a separate environment from my main or OS environment because I have a few project that using python with different version of library.

For this practice I’m using envforodoo13. Then activate the environment

Install the requirements using pip install -r requirements.txt

1.3 Postgres

I think the doc already give detailed how to. It’s pointed out that we should create new user and not using the default user. So maybe I don’t need to put longer explanation in here. But here goes.

Open pgAdmin
Go to Login/Group Roles
I’m using odoodb_admin as user for postgres
Set Password. I’m setting to admin.
Set Privileges. Can Login ? And Create Database to YES as pointed in odoo doc.
Create database odoo13db.

1.4 Microsoft Build Tools

Same here I think the document already have detail explanation. But from my experiences, I already have Visual Studio 2019 CE with the build tools. And I forgot how to install it.

1.5 Running Odoo

I have few difficulties in first time running Odoo, it’s been a while so I don’t remember that much. In document they use this command to run Odoo

python odoo-bin -r dbuser -w dbpassword --addons-path=addons -d mydb

But it turn out that I have to use –init=base to load odoo with data. You can read the command line reference here https://www.odoo.com/documentation/13.0/reference/cmdline.html#reference-cmdline-server-database

so go to odoo directory then run

python odoo-bin -r odoodb_admin -w admin --addons-path=addons -d odoo13db –init=base

but too bad I got error

It turns out we don’t have odoo-bin file. If you go to github, the odoo-bin files is there. But I download it from https://www.odoo.com/page/download doesn’t contain odoo-bin.

I compare the two download zip files it turn out to be quite different.

I try to run it again but got error. It seems that it can’t find addons directory.

It seems that the addons directory located inside the odoo directory so it should be like this

python odoo-bin -r odoodb_admin -w admin --addons-path=odoo/addons -d odoo13db –init=base

we counter a few error but now it working.

Wait for few minutes to load and create the data and you can go to http://localhost:8069/ to view the result or login page.

Use (username and password) admin for admin role and (username and password) demo for demo role

Module Development

This also review from existing Odoo document and making this review also as cheat sheet for personal use or anyone who want use it. If you want to use it immediately you should read Getting Started with Odoo or in Odoo terms it’s General use, here is the link https://www.odoo.com/documentation/user/13.0/general.html

Getting familiar with Odoo User Interface and basic of the General Use will have a benefit for longer time.

Now lets get back to reviewing the module development. From the document

https://www.odoo.com/documentation/13.0/howtos/backend.html#build-an-odoo-module

what we can learn is

Basic understanding Module Composition
Create module using scaffold command
Model creation and basic understanding about ORM in Odoo
Creating Menu and also understanding Action

But from this we still can’t see it in action in the app because you have to go to

https://www.odoo.com/documentation/13.0/howtos/backend.html#basic-views

to learn about the front-end or Views creation.

With these 2 simple courses you just create basic CRUD (create, read, update, delete) with additional feature without having too much code. But you still have to update Access Rights so User or the Admin can use the module.

Too make it simple here is the cheat sheet.

Scaffold first for the base module then loop this

Create model function/method.
Update the view, create Tree and Form view
Update the menu. So you can test it in browser
Update the Access Rights or you won’t see the Menu and can’t access the view
Re-run odoo-bin with arguments -u <module_name> to update what you make or changes

In the Odoo document they not mention that you have to update the access rights after the Basic View Course. I’m having a hard time searching why my menu doesn’t show up in the main menu.

I will do the exercise first the OpenAcademy module the Course model then try a new model with different name.

So anyway Now lets try the exercise from Odoo document and review it one by one and also testing it.

From the document exercise we have to invoke the command scaffold. From the next image you can see that we have to invoke in the command line.

The document tell us to invoke the command and put it into addons directory. But that will make the modules being save in addons directory along with other modules that Odoo already use. It will make you hard to manage.

Because of that, I choose to create directory of my own. So it will be easier to manage. For now create myaddons directory inside Odoo directory so the directory will be at the same level with addons directory. You can use mkdir command or just use right click > new folder. The next image will show you where to put it.

so if you follow along from the beginning just use your virtual environment and type

python odoo-bin scaffold openacademy odoo/myaddons

it will automatically create the necessary files for empty modules as the image shown below.

So now you know how to create a module, but it doesn’t stop here because we just only create an empty modules or in other words just creating a directory, with simple files. Next we’re going to create a class in model.py. You can read more about models in the document here https://www.odoo.com/documentation/13.0/reference/orm.html#models . But if you just wanna know from me then to make it simple its just a representation of table in database or a storage.

Now let’s go and create Course model. In the document it says that we have to edit the models.py files in openacademy/models directory. You can also create another files if you don’t want to create in models.py but you have to edit other files so your files is loaded by Odoo framework. Anyway we wont do that right now. So go ahead edit the models.py just the same as document told you to do. Below is the image before edit.

and after edit it becomes.

As you can see it’s all the same with the document.

You can run the odoo-bin to test if you made some error in editing models.py or not. If you want to test it out just add argument -u openacademy in the command line

if it says Modules loaded after updating modules list. Then it means your code is working just fine. Next we’re going to create Menu and Action for the Menu. I know I’m skipping the Data files exercise just because I won’t add data using files I will add later using the form.

Menu in Odoo is being created in xml files that being loaded into the application as long as the files is written in openacademy/__manifest__.py files. The document told us to create new files and add some line in views/openacademy.xml. But right now I’m just gonna write in views.xml because the files its a default files when it modules being generated through scaffold. As you can see in the next image of __manifest__.py.

And the next image is the default files of view.xml which already contains xml tag <menuitem>.

Next image will show you a bit different than the document. I think the result should be the same.

It’s should be fine if you try to run the update again

With this we have a basic Menu and Action with a simple view. But we still can view it in the app.

let’s just try it. Make sure the odoo-bin is running after update. And go to localhost:8069 and login using username : admin and password : admin.

If you see in the main menu. Our Open Academy Menu still not show. That just because the modules have not being installed in Odoo.

To Install the modules go to Apps, search module OpenAcademy. If you can’t find it like image below.

Try to tick off the Apps Tag so it will show every modules that named openacademy. Below is the image if we tick off the Apps Tag.

Go ahead and Install it.

Even after install the modules. The menu doesn’t show. That’s why we need the security files to let the user have access to it.

First un-comment ‘security/ir.model.access.csv’ in __manifest__.py.

And edit the ir.model.access.csv file.

If you notice. I’m using base.group_user as group id that can have access. This is just temporary as the Odoo document will be using group_manager as group id.

You can try to update the app again. Restart the command line odoo-bin and don’t forget to use -u openacademy as argument. Refresh the browser then see the menu will be shown in main menu.

And if you try to click it, it will redirect user to Open Academy List view.

You can now try and test the Create Button and start input sample data.

If it’s work the data will be saved and can be shown in the list view.

I think that’s it for today. Don’t forget to check the security part in the Document otherwise you’ll get confused on how to manage access rights here the link

https://www.odoo.com/documentation/13.0/howtos/backend.html#security

That’s it for today I will be editing this and adding some new sample.
after try to view this writing for few times. maybe i need to make it into parts. so when the page load it will load a bit faster

~~***STILL ON PROGRESS***~~

I think this article is done. for the basic module development and as a cheat sheet for my future development. next one will be tips n trick or extending base module like res.partner and other base module (i still don't know which one is base).

Anyway if you done reading this and reach the end of page. Thank you from bottom of my heart.
