How to use Logstash cookbook

user3421490 — Thu, 01 Oct 2015 14:57:02 +0000

I'm trying to use https://github.com/lusis/chef-logstash cookbook and running Chef solo, my node.js looks like this:

{    
"logstash": {
"instance_default":{
  "config_templates_cookbook": "aws-logstash",
  "inputs": [{"file": {"path":"/var/log/messages","type":"messages"}}],
  "config_templates": {"myagent": "agent.conf.erb"}
  }},
 "run_list": ["recipe[logstash::agent]"]}

The only attributes I can override are config_templates_cookbook and config_template. I am not able to define inputs, filters or outputs via variables. Sure defining all options under agent.conf.erb could work but it defeats the purpose of the cookbook a bit. Can anybody help with a way to get it to work.

Thanks

Grape API service response 400 bad request at Rails 4 when I sending a json request to it using curl

Howardsun — Thu, 01 Oct 2015 14:44:56 +0000

I don't know how to solve the 400 bad request that API service gives back to me. All I need are receiving json responses from API service, and the API service could communicate with many-type devices.

I'm building an all-json-request API service according to tutorial of Grape gem at GitHub.com https://github.com/ruby-grape/grape and GitHub.io http://intridea.github.io/grape/docs/index.html . After I sending a json request to the API service: localhost:3000/specified_vegetables using curl, which is construct with Grape gem version 0.8.0 and located at new empty Rails 4.1.1 project, the API service give back the response:

*   Trying ::1...

My curl request command: curl -H 'Accept: application/json' -H 'Content-Type:application/json' -X GET http://localhost:3000/specified_vegetables/ -d '{"transaction_date" : "20131031", "name" : "金針筍"}' -v In my database, there is one record matched the conditions I've queried.

The log of rails server runs and it also includes the curl request:

                        end
                end
       end
end

The only one model in Rails app is SpecifiedVegetable.rb:

class SpecifiedVegetable < ActiveRecord::Base
        self.table_name = "specified_vegetable"
end

In config/application.rb file, I add two lines in rails Application class:

config.paths.add "app/api", glob: "**/*.rb"
config.autoload_paths += Dir["#{Rails.root}/app/api/*"]

In config/routes.rb file, I add one line in Rails.application.routes.draw:

mount AgricultureTransaction::Base => '/'

Above of all are information I could provide. Please help me to solve this problem or give me some keywords to search. I've find some articles, but they could not help me.

Erro instaling compass in OSX Yosemite

DonMicillo — Thu, 01 Oct 2015 14:38:37 +0000

Good day I have a Mac with OSX Yosemite I'm trying to install the compass with the command:

sudo gem install compass

but I am getting the following error:

Building native extensions.  This could take a while...
ERROR:  Error installing compass:
    ERROR: Failed to build gem native extension.

`for_fd': not a socket file descriptor

Hugo Corrá — Thu, 01 Oct 2015 14:13:31 +0000

I've installed Redmine, it's working fine as long as I use the development server. Now I'm trying to configure it to run under apache, using fastcgi. The following message is being showed:

/usr/local/share/gems/gems/fcgi-0.9.2.1/lib/fcgi.rb:54:in `for_fd': not a socket file descriptor (ArgumentError)
        from /usr/local/share/gems/gems/fcgi-0.9.2.1/lib/fcgi.rb:54:in `default_connection'
        from /usr/local/share/gems/gems/fcgi-0.9.2.1/lib/fcgi.rb:40:in `each'
        from /usr/local/share/gems/gems/rack-1.4.7/lib/rack/handler/fastcgi.rb:27:in `run'
        from ./dispatch.fcgi:20:in `<main>'

Looks like the problem is something related to sockets in ruby, to make it easy, I've isolated the problem:

#!/usr/bin/env ruby
require 'socket'
s=Socket.for_fd(STDIN.fileno)

When I try to run the code above, the same message is being showed:

/tmp/test.rb:5:in `for_fd': not a socket file descriptor (ArgumentError)

Since I'm not a ruby programmer, I would like to understand, what is happening?

Making a variable depend on the value of another in FactoryGirl

DJA — Thu, 01 Oct 2015 13:45:35 +0000

I have the following problem. I have a model in which there is a validation of a variable (amount) depending on the value of another enum variable (kind).

class ScopeChange < ActiveRecord::Base

enum kind: [ :add, :remove, :change ]

validates :amount, :numericality => { :greater_than_or_equal_to => 1 } , if: "self.add?"
validates :amount, :numericality => { :less_than_or_equal_to => -1 } , if: "self.remove?"

end

And I want to create a Factory that builds this, I have tried putting the if statement inside the actual creator of the variable (it should be an if elsif else statment, this was just made for testing)

FactoryGirl.define do
  factory :sprint_scope_change do
    association :sprint
    kind { Faker::Number.between(0,2) }
    amount { kind == :add ? Faker::Number.between(-7,7) }
    date { Faker::Date.between(sprint.start_date, sprint.end_date) }
    description { Faker::Lorem.sentence }
  end
end

which didn't work, it completely ignored the if statement and just created a random number between -7 and 7. The next thing I tried was making a variable outside the factory :sprint_scope_change and inside it:

FactoryGirl.define do

  factory :sprint_scope_change do

    sprint_scope_change.kind = Faker::Number.between(0,2)

    sprint_scope_change.amount = if sprint_scope_change.kind == 0
      Faker::Number.between(1,7)
    elsif sprint_scope_change.kind == 1
      Faker::Number.between(-7,-1)
    else
      Faker::Number.between(-7,7)
    end

    association :sprint
    kind { kind }
    amount { amount }
    date { Faker::Date.between(sprint.start_date, sprint.end_date) }
    description { Faker::Lorem.sentence }
  end
end

which worked in a way, but it gave the exact same value everytime I called the Factory. The last way that I tried was with a before(:create), but now the program just explodes and "stack level is too deep", I tried to reproduce some examples that I've seen but something is definitely wrong:

FactoryGirl.define do

factory :sprint_scope_change do
  before(:create) { |sprint_scope_change|

    sprint_scope_change.kind = Faker::Number.between(0,2)

    sprint_scope_change.amount = if sprint_scope_change.kind == 0
      Faker::Number.between(1,7)
    elsif sprint_scope_change.kind == 1
      Faker::Number.between(-7,-1)
    else
      Faker::Number.between(-7,7)
    end
  }

  association :sprint
  kind { kind }
  amount { amount }
  date { Faker::Date.between(sprint.start_date, sprint.end_date) }
  description { Faker::Lorem.sentence }

  end
end

What can I do to achieve what I try to do? What is wrong with what I have tried so far? Any of this questions would be nice to know.

(It is also worth saying that I am also new in rails and ruby)

Rspec testing rake tasks

Carl Markham — Thu, 01 Oct 2015 13:13:13 +0000

I have a simple rake task with a puts in it

namespace :atask
  task something: :environment do
    puts 'Foo'
  end
end

My spec is as follows

describe 'atask:something' do
  before { MyApp.Application.load_tasks }

  context 'one' do
    it do
      Rake::Task['atask:something'].invoke
    end
  end

  context 'two' do
    it do
      Rake::Task['atask:something'].invoke
    end
  end

  context 'three' do
    it do
      Rake::Task['atask:something'].invoke
    end
  end
end

As you can see it has 3 contexts and 3 it blocks. So I should see 'Foo' in the console three times, once for each time the task is invoked. However, I only see 'Foo' once in the console even though it is invoked three times.

mongoid_search and frequency of updates

Kevin Brown — Thu, 01 Oct 2015 13:04:14 +0000

The mongoid_search gem needs to index records to work properly. It does this with a rake task...but this needs to be run each record destroy or create to really work well. Is this a good idea to use? Should I just run that rake task after each destroy/create for each model?

Can someone help me understand what's best practice? Should this be a cron task?

Avoiding basic auth with Selenium (using Ruby)

user2808225 — Thu, 01 Oct 2015 13:02:50 +0000

Well, the code is basically

d = Selenium::WebDriver.for :firefox, :profile => "myApp"
d.get("http://login:password@myapp.local")

And still firefox shows basic auth dialog window. I use the profile setting for FF so it hopefully remembers it and lets me through, but in reality it just remembers it and you still have to hit enter.

Kinda out of ideas here.

P.S. Yes, i double checked that login:password are totally correct.

How to show field from a table that connects another table?

Sebastian Plasschaert — Thu, 01 Oct 2015 13:01:14 +0000

I have a Project model that can contain many Products through the model Benefit (and vice versa for the Product model). Within the Benefits tabel a project_id and product_id are uniquely indexed.

I've created the Benefit model to be able to add a product to multiple projects and I want to add extra data through every benefit (benefit.title etc.).

I'm able to show the products per project, but I'm not able to show any other benefit.value.

My Project model is connected to Benefits like this:

has_many :benefits
has_many :products, through: :benefits

In my Project view (show.html.erb) I'm showing my product field like this:

<% @products.each do |product| %>
                    <%= link_to [product.project, product] do %>    
                        <div class="row">
                                <div class="col m3">
                                    <img height="20" src="<%= product.image %>"></img>
                                </div>
                                <div class="col m3">
                                    <%= product.name %>
                                </div>
                                <div class="col m3 truncate">
                                    <%= product.content %>
                                </div>                                  
                                <div class="col m3">
                                    <i class="tiny red-text material-icons right">favorite_border</i>
                                </div>
                        </div>
                    <% end %>
                <% end %>

But it tells me that I'm using an undefined local variable or method 'Benefit', when I try to add the following:

<% @products.each do |product| %>
                    <%= link_to [product.project, product] do %>    
                        <div class="row">
                                <div class="col m3">
                                    <img height="20" src="<%= product.image %>"></img>
                                </div>
                                <div class="col m3">
                                    <%= product.name %>
                                </div>
                                <div class="col m3 truncate">
                                    <%= benefit.title %>
                                </div>                                  
                                <div class="col m3">
                                    <i class="tiny red-text material-icons right">favorite_border</i>
                                </div>
                        </div>
                    <% end %>
                <% end %>

Any ideas on how I should handle this?

How to properly use lookahead in Ruby Regex?

ciaoben — Thu, 01 Oct 2015 12:30:14 +0000

I am expecting this to match only the first instance of <style, because the second one, after the space has the pattern that I have put in the negative lookahead.

"<style type=\"text/html\">ciaoxocs <style />".scan /<style\s?(?!\/>)/
# => ["<style ", "<style"]

I want to an explanation for what is happening here, and possibly a better solution to match only the first instance without matching the closing tag with or without space:

<style /> or <style/>

In regex101.com, it works as expected with other langs:

Ruby: generating controller in rails won't gets error

Do we have a Python or Ruby equivallent of assign variable with contents of another variable that will change dynamicall as in PHP? [duplicate]

Sumanogeek — Thu, 01 Oct 2015 12:04:04 +0000

This question already has an answer here:

How do I pass a variable by reference? 16 answers

Recently I came across a PHP program that use "= &" assign variable value with reference to another variable as in below example.

$var1 = 'val-A';    #Assign any value to variable $var1
$var2 = &$var1;     #Assign value of variable $var1 to variable $var2 by reference "= &"
$var3 = $var1;      #Assign value of variable $var1 to variable $var3 as usual

$var1 = 'val-X';    #Change value assigned to variable $var1

echo '$var1 = ' .$var1; #printed the changed value "val-X"
echo '$var2 = ' .$var2; #printed the changed value "val-X" not sure if this can be accomplished in Python or Ruby.
echo '$var3 = ' .$var3; #printed the unchanged value "val-A"

"$var2 = &$var1" Can this be accomplished in Python or Ruby ? or is there a equivalent that will accomplish this ?

user60679 — Thu, 01 Oct 2015 11:54:30 +0000

My file is mentioned below:

[Suresh
asdfala
adsfafa
sdfasdfa
asdfas
asdfasdfasd
[Sala
sdfadsf
adsfasd
asdfa
wewet

Based on the delimiter "[", I want to separate the lines. I want an output like:

[Suresh asdfala adsfafa sdfasdfa asdfas asdfasdfasd

[Sala sdfadsf adsfasd asdfa wewet

Pubnub publish not publishing

Adnan Ali — Thu, 01 Oct 2015 11:04:52 +0000

I am trying to publish a message to pubnub channel but its not publishing on server. However its working absolutely fine on local machine. Any idea where I am doing it wrong?

class Message < ActiveRecord::Base

  after_create :send_message_to_driver

  def send_message_to_ABC
    $pubnub.publish(
        channel: "chat_ABC",
        message: message
    ) do |env|
      puts env.parsed_response
    end
  end
end

$pubnub is being initialized globally for app.

Conditionals in ruby

Charllie — Thu, 01 Oct 2015 09:35:17 +0000

I want to create conditions.

# Find the sum of all the multiples of 3 or 5 below 1000.
sum = 0
for i in 0..1000 do
  if i % 3 == 0
    sum += i
  end
  elsif i % 5 == 0
    sum += i
  end
  else next
  end
end
puts sum

I receive a syntax error. I will appreciate any form of help. I do not know what I did wrong.

Ruby libXML Xpath find returns result in result

GTeley — Thu, 01 Oct 2015 09:06:06 +0000

Parsing a XML document with Ruby libXML i noticed a strange behaviour. When searching for some elements and traversing the result, I get the result object back in the result itself.

Here's an example XML

<?xml version="1.0" encoding="UTF-8"?>
<main>
    <projects>
        <project id="1">
            <name>Project 1</name>
            <van>Guus</van>
        </project>
        <project id="2">
            <name>Project 2</name>
            <van>Guus</van>
        </project>
    </projects>
</main>

Parsing the code (controller):

 @projects = @xmlDoc.find('//project[@id]/name')

Displaying it (view):

<ul>
<%= @projects.each do |pr| %>
    <li><%= pr.first.content %></li>
<% end %>
</ul>
<hr>
<%= @projects.inspect%>

Results in:

- Project 1
- Project 2
  #<LibXML::XML::XPath::Object:0x000008153182c0>  
------------------------------------------------------------------------
#<LibXML::XML::XPath::Object:0x000008153182c0>

As you can see, the list contains the XPath object self. I intentionally displayed it as a bullet list and an inspect after a horizontal line. As you can see, the last item does not have a bullet in front of it. But where does it come from? Am I missing something or is this a bug?

How do I find Capybara::Node::Element that corresponds to Selenium::WebDriver::Element

Nakilon — Thu, 01 Oct 2015 09:02:16 +0000

There is a node, that I find by coordinates and wish to execute a relative xpath query on it, so I probably need a Capybara object (Capybara::Node::Element) for .find(:xpath, but the object I get from evaluate_script("document.elementFromPoint is a Selenium object (Selenium::WebDriver::Element).

Rails uninitialized constant error in controller

Coda Chang — Thu, 01 Oct 2015 04:09:31 +0000

Here is my controller directory structure

controllers/
.........../dashboard
...................../admin
.........................../admin_controller.rb
.........................../item_controller.rb
........../items_controller.rb

I expect that manager can add new item, and users can see all items.

I typed rails g scaffold dashboard/admin/items to quickly generate controller with namespace.

And I modified @dashboard_admin_items = Dashboard::Admin::Item.all

to @dashboard_admin_items = Item.all

controllers/dashboard/admin/items_controller.rb

class Dashboard::Admin::ItemsController < Dashboard::Admin::AdminController
  before_action :set_dashboard_admin_item, only: [:show, :edit, :update, :destroy]

  # GET /dashboard/admin/items
  def index
    @dashboard_admin_items = Item.all

  end
...

But it threw this error

Also, I've put this project on github.

Update

view/dashboard/admin/items/index.html.erb

<tbody>
    <% @Items.each do |i| %>
      <tr>
        <th><%= i.id %></th>
        <th><%= i.name %></th>
        <th><%= i.price %></th>
        <!-- <td><%#= link_to 'Show', dashboard_admin_item %></td> -->
        <td>
          <%= link_to 'Edit', edit_dashboard_admin_item_path(dashboard_admin_item) %>
          <%= link_to 'Destroy', dashboard_admin_item, method: :delete, data: { confirm: 'Are you sure?' } %>
        </td>
      </tr>
    <% end %>
  </tbody>

def index
    @Items = Item.all
end

How to refresh the database connection

do_Ob — Thu, 01 Oct 2015 03:06:40 +0000

I inserted a column in mysql using my terminal then in rails I tried to get the columns,

puts (Class.new(ActiveRecord::Base) { self.table_name = 'sample_tables'}).column_names

but it will not show the inserted column. I need to refresh my rails first to show it. What code do I need to add to refresh the connection before getting the columns?

I tested it using rails c. Thanks in advance for the help.

BTW, I tried this

(Class.new(ActiveRecord::Base) { self.table_name = 'sample_tables'}).reload

but it's not working.

Rails Nested Resource not creating from Array

M. Wood — Thu, 01 Oct 2015 01:08:25 +0000

I am trying to create a simple data puller from the yahoo finance gem. I have a nested route setup for Security that has_many Price

The Price controller is as follows:

class PricesController < ApplicationController
  before_action :set_security
  before_action :set_price, only: [:show, :edit, :update, :destroy]

  def new
    @price = Price.new
  end

  private
  def set_price
    @price = Price.find_by_name(params[:id])
  end

  def price_params
    params.require(:price).permit(:date, :open, :high, :low, :close, :volume, :security_id)
  end

  def set_security
    @security = Security.find_by_ticker(params[:security_id])
  end
end

The nested route works fine to manually create the child Price record from a form. I'm trying to create a Price record for each result in the array that gets generated from the following code:

class Datapuller

  def self.download_historical
    yahoo_client = YahooFinance::Client.new
    data = yahoo_client.historical_quotes("FB")

    data.each do |i|
      @ticker = Security.find_by_ticker(data[0].symbol )
      price = @ticker.prices.new()
      price.security_id = @ticker
      price.date = data[0].date
      price.open = data[0].open
      price.high = data[0].high
      price.low = data[0].low
      price.close = data[0].close
     end
   end
 end

I'd like to call this method from a button link but for now I have the following code on the Security View:

<%= Datapuller.download_historical %>

This also give me the benefit to see the data that is getting loaded from the array.

With the above code I can create a child Price to a parent Security using a form and I can make the call from the yahoo finance gem. However, the array is not creating a Price record for each line in the array.

What am I missing in this?

Thanks!

How does capybara/selenium grab current URL? Issue with single page site

Trivial — Wed, 30 Sep 2015 15:58:18 +0000

I am using ruby and capybara(which leverages selenium) to automate walking through a website. After navigating to a new page I verify that the new page URL is what i'm expecting. My issue comes when I walk through an order funnel that is a single page but loads different views.

Some code...

I create my session instance then have additional code opening the browser and walking to a certain point in the website that I wont include

$session = Capybara::Session.new(:selenium)

My line for checking the browser URL without search params ie: everything after '?'

if url == $session.current_url.to_s.split("?")[0]
        urlCorrect = true
end

This code works fine when my URL is

https://www.homepage.com

Then I click on a link that takes me to my order funnel ... https://www.homepage.com/order#/orderpage1?option1=something&option2=somethingelse

My function still matches the expected URL. But the issue comes when I move to the second page of the order funnel :

https://www.homepage.com/order#/orderpage2?option1=something&option2=somethingelse

My capybara code to get current url still returns the URL from orderpage1. Im guessing its because there is no postback when moving from orderpage1 to orderpage2 but i dont know how to force a postback or tell capybara to re-grab the url

Any advice will be appreciated.

Thanks

Quick Edit: I forgot to mention this behavior is only in IE. Chrome and Firefox both work correctly with the exact same code

Will paginate rails limit num of pages to max 10?

Sumeet — Wed, 30 Sep 2015 13:14:55 +0000

I am using will paginate for pagination. I have total 11 pages currently. At footer it shows all the 11 pages no matter on what page the user is. How can I display max 10 pages at footer. So if user comes on page no 5 it will show 5 pages before and after. Not all at once.

Rails nested group and count with column renaming

ste26054 — Wed, 30 Sep 2015 08:52:53 +0000

I have a model which looks this way:

Issue(id, ..., tracker_id)
                   |
          Tracker(id, ..., name)

Issue has_one :tracker
Tracker has_many :issues

And I would like to get the number of Issues per Tracker. What I have got is:

Issue.group(:tracker_id).count => {3=>446, 5=>247, 9=>2, 11=>560}

But instead of grouping by tracker_id, I would like to group by tracker_name, to get this:

{"name_1"=>446, "name_2"=>247, "name_3"=>2, "another_name"=>560}

Is there a way to do this directly, without any mapping operation / hash renaming ?

Ruby Time.now.to_i PHP equivalent

bsteo — Sat, 26 Sep 2015 07:53:16 +0000

Any idea how can I get the same result as with Ruby in PHP? Unix epoch time.

timeint = Time.now.to_i
puts timeint

Result:

1443253948

I tried http://php.net/manual/en/function.time.php but not much good result.

EDIT:

Seems this does the trick, never thought about:

$epoch = time();

Ruby-Mp3Info error when saving/closing a file

JRQ — Mon, 30 Jun 2014 18:26:15 +0000

I've upgraded to the new mp3info GEM and now there seems to be a problem when it comes to writing the changes to the MP3 tags. Ruby version 1.9.3, mp3info version 0.8.4, Windows 7 - 64 bit.

Simple program:

require 'mp3info'
mp3 = Mp3Info.open('a.mp3')
mp3.title = 'bogo'
mp3.close

Results in:

Errno::EACCES: Permission denied - (./.a.mp3.tmp, a.mp3)
from D:/Ruby193/lib/ruby/gems/1.9.1/gems/ruby-mp3info-0.8.4/lib/mp3info.rb:453:in `rename'

I've checked permissions on the file/folder, and I'm running as Administrator in the CMD shell.

Rails 4: assets not loading in production

emersonthis — Mon, 09 Sep 2013 14:09:53 +0000

I'm trying to put my app into production and image and css asset paths aren't working.

Here's what I'm currently doing:

Image assets live in /app/assets/images/image.jpg
Stylesheets live in /app/assets/stylesheets/style.css
In my layout, I reference the css file like this: <%= stylesheet_link_tag "styles", media: "all", "data-turbolinks-track" => true %>
Before restarting unicorn, I run RAILS_ENV=production bundle exec rake assets:precompile and it succeeds and I see the fingerprinted files in the public/assets directory.

When I browse to my site, I get a 404 not found error for mysite.com/stylesheets/styles.css.

What am I doing wrong?

Update: In my layout, it looks like this:

<%= stylesheet_link_tag    "bootstrap.min", media: "all", "data-turbolinks-track" => true %>
<%= stylesheet_link_tag    "styles", media: "all", "data-turbolinks-track" => true %>
<%= javascript_include_tag "application", "data-turbolinks-track" => true %>

The generate source is this:

<link data-turbolinks-track="true" href="/stylesheets/bootstrap.min.css" media="all" rel="stylesheet" />
<link data-turbolinks-track="true" href="/stylesheets/styles.css" media="all" rel="stylesheet" />
<script data-turbolinks-track="true" src="/assets/application-0c647c942c6eff10ad92f1f2b0c64efe.js"></script>

Looks like Rails is not properly looking for the compiled css files. But it's very confusing why it's working correctly for javascripts (notice the /assets/****.js path).

Activeadmin: disable pagination when exporting xml/json

RomanKapitonov — Wed, 06 Feb 2013 16:21:33 +0000

How can I disable pagination for json/xml export in activeadmin? I could't figure out any solution for this. I'm getting only current page when hitting export to xml or json.

How can I skip a specific validation when importing data?

Nathan Long — Mon, 03 Dec 2012 15:43:37 +0000

How can I skip a specific model validation when importing data?

For example, suppose I have this model:

class Account
  validates :street_address, presence: true
end

Normally, I don't want accounts to be saved without addresses, but I'm also going to convert a lot of data from an old system, and many accounts there don't have addresses.

My goal is that I can add the old accounts to the new database, but in the future, when these accounts are edited, a street address will have to be added.

Clarification

As I said, I want to skip a specific validation; others should still run. For example, an account without an account number shouldn't be loaded into the new system at all.
