Latest #OpenERP R&D news: native bar-code support for mobile warehouse management! pic.twitter.com/92EcrXPAkS — Fabrice Henrion (@fheopenerp) May 9, 2014

Visit http://twitter-wall.appspot.com/ to create news wall for free !

Twitter Wall is free solution to create a News walls based not he favorite tweets from the Twitter for your event. What you need to do is just to pass the Twitter username of your company in order to display the favorite your tweets. You can control your favorite tweets from Twitter will be catch by the Twitter Wall at the interval of 2 minutes.

Lets see how you can make your own Twitter API Library in Python using urllib2 and json library that call Twitter’s API Internally. Few steps we have to perform In order to get the Twitter’s API access.

Create a Apps

You have to create a Twitter App that will ask you few informations and generates the API and Secret Key. Visit https://apps.twitter.com and login with your twitter account.

You can Test and generate  the signature for the different services for Twitter OAuth API. you can get the list of API provided by Twitter from API Console.

• https://api.twitter.com/1.1
• https://stream.twitter.com/1.1
• https://userstream.twitter.com/1.1
• https://sitestream.twitter.com/1.1
• https://api.twitter.com/oauth

Well It is not full updated, but provides a testing for different version such API 1 and API 1.1. Next thing after setting up an application is to Obtaining access tokens that will used to make an API request.

We can make a service endpoints for our API as below

API_VERSION = '1.1'
API_ENDPOINT = 'https://api.twitter.com'
REQUEST_TOKEN_URL = '%s/oauth2/token' % API_ENDPOINT
REQUEST_FAVORITE_LIST = '%s/%s/favorites/list.json' % (API_ENDPOINT, API_VERSION)
REQUEST_TWEET_LIST = '%s/%s/statuses/user_timeline.json' % (API_ENDPOINT, API_VERSION)

Obtaining access tokens

In order to make authorized calls to Twitter’s APIs, your application must first obtain an OAuth access token on behalf of a Twitter user or you could issue Application-only authenticated requests when user context is not required. The way you will obtain such tokens will depend on your use case. Get details if you want to access Twitter other then Application-only authentication method.

    def connect(self):
        '''
        connect to twiter api end-point https://api.twitter.com/oauth2/token
        and obtain an oauth token
        '''
        bearer_token = '%s:%s' % (self._api_key, self._api_secret)
        encoded_bearer_token = base64.b64encode(bearer_token.encode('ascii'))
        request = Request(REQUEST_TOKEN_URL)
        request.add_header('Content-Type', 'application/x-www-form-urlencoded;charset=UTF-8')
        request.add_header('Authorization', 'Basic %s' % encoded_bearer_token.decode('utf-8'))
        request.add_data('grant_type=client_credentials'.encode('ascii'))

        try:
            response = urlopen(request)
        except urllib2.HTTPError, e:
            logging.error('HTTPError = ' + str(e.code))
        except urllib2.URLError, e:
            logging.error('URLError = ' + str(e.reason))
        except httplib.HTTPException, e:
            logging.error('HTTPException')
        except Exception:
            import traceback
            logging.error('generic exception: ' + traceback.format_exc())

        raw_data = response.read().decode('utf-8')
        data = json.loads(raw_data)
        return data['access_token']

Get Favorite Tweet

Once you success with obtaining a token you can make call to any Twitter API. You need to get the correct service endpoint from where you can get the favorite list, as we have obtain token for Application-only authenticated requests it is not a user context we need to pass Screen name.

    def _execute(self, url, params):
        params_encode = urllib.urlencode(params)
        full_url = "%s?%s" % (url, params_encode)

        request = Request(full_url)
        request.add_header('Authorization', 'Bearer %s' % self._token)
        try:
            response = urlopen(request)
        except urllib2.HTTPError, e:
            logging.error('HTTPError = ' + str(e.code))
        except urllib2.URLError, e:
            logging.error('URLError = ' + str(e.reason))
        except httplib.HTTPException, e:
            logging.error('HTTPException')
        except Exception:
            import traceback
            logging.error('generic exception: ' + traceback.format_exc())
        raw_data = response.read().decode('utf-8')
        data = json.loads(raw_data)
        return data

    def getFavourites(self, screen_name, count=20):
        params = {'count': count, 'screen_name':screen_name}
        data = self._execute(REQUEST_FAVORITE_LIST, params)
        return data

Users Tweet

Call with the same token to another service point with different arguments, and we can get the user’s tweets.

    def getTweets(self, screen_name):
        params = {'screen_name':screen_name}
        data = self._execute(REQUEST_TWEET_LIST, params)
        return data

Almost all the API’s method called with GET method and returns the JSON data when they called, We can also update the data on twitter using Twitter API too which can be call using the POST method.

Limits per window by resource

Rate limit window duration is currently 15 minutes long. Curious how rate limiting works in API v1.1? Read REST API Rate Limiting in v1.1.

Known for their extensive range of pragmatic IT ebooks, Packt Publishing are celebrating their 2000th book title `Learning Dart’– they want their customers to celebrate too.

To mark this milestone Packt Publishing will launch a ‘Buy One Get One Free’ offer across all eBooks on March 18th – for a limited period only.

`Learning Dart’ was selected as a title and published by Packt earlier this year. As a project that aims to revolutionise a language as crucial as JavaScript, Dart is a great example of an emerging technology which aims to support the community and their requirement for constant improvement. The content itself explains how to develop apps using Dart and HTML5 in a model-driven and fast-paced approach, enabling developers to build more complex and high-performing web apps.

David Maclean, Managing Director explains `It’s not by chance that this book is our 2000th title. Our customers and community drive demand and it is our job to ensure that whatever they’re working on, Packt provides practical help and support.

At Packt we understand that sometimes our customers want to learn a new programming language pretty much from scratch, with little knowledge of similar language concepts. Other times our customers know a related language fairly well and therefore want a fast-paced primer that brings them up to a competent professional level quickly.

That’s what makes Packt different: all our books are specifically commissioned by category experts, based on intensive research of the technology and the key tasks.’

Since 2004, Packt Publishing has been providing practical IT-related information that enables everyone to learn and develop their IT knowledge, from novice to expert.

Packt is one of the most prolific and fast-growing tech book publishers in the world. Originally focused on open source software, Packt contributes back into the community paying a royalty on relevant books directly to open source projects. These projects have received over $400,000 as part of Packt’s Open Source Royalty Scheme to date.

Their books focus on practicality, recognising that readers are ultimately concerned with getting the job done. Packt’s digitally-focused business model allows them to quickly publish up-to-date books in very specific areas across a range of key categories – web development, game development, big data, application development, and more. Their commitment to providing a comprehensive range of titles has seen Packt publish 1054% more titles in 2013 than in 2006.

Erol Staveley, Publisher, says `Recent research shows that 88% of our customers are very satisfied with the service knowing that we offer a wide breadth of titles in a timely manner, and owing to the quality of service that they receive 94% of customers are willing to recommend Packt to friends and family. It’s great that we’ve hit such a significant milestone, and we want to continue delivering this fantastic content to our customers.’

Here are some of the best titles across Packt’s main categories – but Buy One, Get One Free will apply across all 2000 titles:

Here is a prototype model that convert filters in to tabs, after installing web module https://www.openerp.com/apps/7.0/web_filter_tabs/.

Here’s an excerpt:

The concert hall at the Sydney Opera House holds 2,700 people. This blog was viewed about 53,000 times in 2013. If it were a concert at Sydney Opera House, it would take about 20 sold-out performances for that many people to see it.

• Track outgoing material through Gatepass
• Track your returnable containers you deliver with products

In this post lets see how we can track materials which was sent outside company for the repairing. In order to get it repair engineer or plant manager have to follow the same request flow. Once the Indent approve for the repairing of product we are ready to deliver product for the repairing and we should get that product back form the supplier with service charges for the repairing.

Based on the predefine contract or invoice received form supplier we can change the service pricing etc, if supplier change new parts you just need to add that in purchase order you will get automatic incoming shipment for that parts in order to add that as a stock in your inventory.

Go through video below to get the full example.

When you sale Oxygen Gas you have to deliver in Cylinder so of course you wan to charge or lease the cylinder with nominal fees, in this example we did the same using packaging cost we add the packaging cost to compute the lease charges and at the time of delivery of course through gatepss we have to define that it is returnable sales in order to get the delver container back.

Enjoy the video

Gatepass is the document prepared by the Warehouse users and attached with delivery order to instruct the gate kipper to allow deliveries or transfer of materials. Based on the types of gate pass system decide that it is returnable material or not. Usually when we sale it is non-returnable materials.

Go through below vides how gate pass is working in OpenERP.

It is mandatory to pay duty on all goods manufactured, unless exempted. For example, duty is not payable on the goods exported out of India. Similarly exemption from payment of duty is available, based on conditions such as kind of raw materials used, value of turnover (clearances) in a financial year, type of process employed etc.

So, for manufacturer it is necessary to keep the track of excise how much they paid on purchase of material and what they collect on sales at the end of the month they have to pay the difference to the Govt. or may get Credit too.

To compute and manage the excise on the  reception of the goods notes we need one some document that takes care for the excise where we can define what we get as an Excise and what we are going to take under exception.

Big manufacturing companies should increase stock once the excise receipt confirm and other cost computes perfectly to keep the stock valuation based on the WAR or Moving WAR method and also issue material on the basic of the WAR to get the correct cost of material consumed.

Once excise receive we get the supplier invoice and based on that we have to prepare the supplier invoice so our invoice policy should be “Invoice based on the Reception” to have all the cost and correct excise what we receive in customer invoice.

Go through video below to see how OpenERP is powerful to manage that complex process through Excise Receipt.

Once you enable Indian specific computation on purchase order you will get more options to select to compute the other cost on Purchase Order. You can also enable other options like Round-Off and discount on the purchase order line.

In OpenERP we have full functional flow to track and manage material or service, what this module add is a new document which will decide the flow according to the requirements and type of document.

Types of Indents

Usually we have two different types of request either material or service. How to satisfy that request is again based on the how we setup our system. Material can be assign from stock or by making purchase.

Approval of Indent

This document route through many identity involved in approval or rejection process in realtime, in this module currently it passed through the Plan manager, Location in term of OpenERP who modify the indent before  approve or reject.

Once, the indent approve based on the request system will issue material either from stock or by purchasing or if request for service it will create a work contract or repairing contracts. For service flow you have to enable some more features on the Indian Localization configurations related to the gate pass and indent.

You can Install / Download module https://www.openerp.com/apps/trunk/l10n_in_base/ from OpenERP Apps Store.

So why we have to prepare a full invoice for that and pay tax on that full invoice upfront? Many countries have tax rules where supplier of service is liable to pay tax on confirmation of sales, which is based on the amount received or based on the invoice generated.

In case of big project or contracts it is better to prepare an invoice with partial product (in this example i use Advance Payment as a partial product) and adjust later on when full project or contract completed, till that time we can pay tax on what amount we received in bank.

To deal with such business cases, advance payment is useful.

In case of contract where supplier have to supply material for a time being it is very easy to manage invoice based on the Warehouse rather then advance payment. OpenERP is allows you to prepare an invoice based on what you are going to deliver to you customer.

Your valuable comments are invited on this functionalities.

You can fine a new module just push to https://code.launchpad.net/~openerp-india/openerp-india/7.0 branch that allows you to prepare a bundle offer with in OpenERP. Please have a look at the video below.

You can download the same module in to your production environment using OpenERP Apps just search for the “quotation_template” or download it from https://www.openerp.com/apps/7.0/quotation_template/.

Same module allows your salesman to prepare a proposal quickly with the pre-defined temples of proposals.

Configure Catch all Email Address

Depending on your email server you need to configure catchall email address, so that none of the email bounce back received by your email server, even if that mailbox dozen’t available, It will be great, if you have only one email address on email server which is catchall so that you can provide rest of all other email address within OpenERP.

Some of the most popular server configuration to create catchall email

• http://support.godaddy.com/help/article/359/setting-up-a-catchall-email-account-in-the-email-control-center
• http://support.google.com/a/bin/answer.py?hl=en&answer=33962
• http://technet.microsoft.com/en-us/library/bb691132(v=exchg.141).aspx
• http://www.cyberciti.biz/faq/howto-setup-postfix-catch-all-email-accounts/

Once you create a catchall email address on your domain, try to check by sending email on that domain with junk email address i.e junk@domain.com, if you receive email in to catchall@domain.com then you have configure your all catchall email address successfully.

Configure Domain in OpenERP

First things after configuring the catchall email address, you have to setup the domain in General Settings under Settings menu of OpenERP. In my case  am using mantayagajjar.in email address.

Once you configure domain in OpenERP, alias have a big role to play while dealing with the incoming and outgoing emails. Each of your user will get automatic email address on that configured domain in terms of alias. Like the same alias is generated for many documents in OpenERP like issue, groups, applicants and yes open-chatter functionality of OpenERP can not run without alias.

Alias in OpenERP

All the alias configured on any documents, users and for specific records are listed under the Alias menu under Emails in the System menu. It is not good to directly deal with the alias, instead better you deal with the related document to change alias (email address).

Lets say for example if you want to change the whole company groups email address from group+whole-company@domain.com to all@domain.com just open the group and edit the alias on that group.

So, now your group is ready to receive an email, to make a test send welcome email to all@domain.com to test whether its working correct or not. You should get an email on your wall that received by all catchall email address and route by all@domain.com email alias in OpenERP.

Keep watching the same blog, where I will explain more about how you can integrate your Enterprise Social Communication to Project, Human Resource and Sales and Purchase very soon.

Some times it is really important to check the analysis of the calls, not for the restriction but for the reflection of the team efforts. For call centers this kind of analysis is most usable (of course it is a draft module and need to improve a lots and need to implement on the same module then crm call lodge.

We can also link the recorded file using URL link and not bu uploading to the OpenERP server, it will be a great features in addition to the module “OpenERP – Asterisk connector“, once a call complete no need to do a lodge call in crm, our configuration will do automatically based on the files available under the asterisk server.

What we need to develop / configure ?

Recorded files should be available by url from the Asterisk server like http://voip.myhost.com/2012/12/exten-201-202-20120615-204337-1339773217.500.wav

Linux based cron job which will execute after every 1 hour, that push a record in OpenERP based on the call recorded files

If you want to play with this module, just download from here with some sample data.

You can see that the LVM group 0 partition have capacity of 448GB and almost 103GB is free but still it shows that the disk is used 100%, which is confusing.

In order to get the correct status of disk, we need to tune the file system using the tune2fs which is basically used to tune for Linux file system for ext2, ext3, and ext4. You can do many things with the tune2fs disk utility, Ubuntu user have seen that even you do normal start and shout down of your laptop but still it forcefully check disk after some specific number of shutdown, tune2fs is responsible to set that number of counts.

When I run command tune2fs to set the reserve disk space with 0 blocks, it tunes the disk for the same and after thaat I got the correct usage according to data and space available on the disk.

[root@loasterisk ~]# tune2fs -m 0 /dev/mapper/VolGroup00-LogVol00
tune2fs 1.39 (29-May-2006)
Setting reserved blocks percentage to 0% (0 blocks)
