It seems like images are included by default only from app/assets folder. So the solution is to add this line to config/application.rb

    config.assets.precompile += %w(*.png *.jpg *.jpeg *.gif)

It sounds Sporker can&#39;t autoload images from vendor/assets/images.

&gt; 2.2 Asset Organization
Pipeline assets can be placed inside an application in one of three locations: app/assets, lib/assets or vendor/assets.

&gt; app/assets is for assets that are owned by the application, such as custom images, JavaScript files or stylesheets.

&gt; lib/assets is for your own libraries&#39; code that doesn&#39;t really fit into the scope of the application or those libraries which are shared across applications.

&gt; vendor/assets is for assets that are owned by outside entities, such as code for JavaScript plugins and CSS frameworks

From the description come from [guides.rubyonrails.org](http://guides.rubyonrails.org/asset_pipeline.html), I don&#39;t think they ignored vendor/assets/images with no intention.

So I just added the follow line:

    #config/application.rb
    config.assets.paths &lt;&lt; Rails.root.join(&quot;vendor&quot;, &quot;assets&quot;, &quot;images&quot;)

And, I solved my problem.
I hope this will work for you.

 

For my Rails 4.2.x project, I just moved the vendor images to `vendor/assets/images` and added this to `application.rb`:

    config.assets.precompile += %w(vendor/assets/images/*)

Works fine on development and production.

I want to use Google&#39;s new measurement protocol for sending tracking events from my server instead of JavaScript.

This page says the client ID is required:
https://developers.google.com/analytics/devguides/collection/protocol/v1/devguide#required


And this page says it&#39;s optional:
https://developers.google.com/analytics/devguides/collection/protocol/v1/parameters#visitor


Plus, the format defined in these docs is different- the first page gives an integer as an example and just says it&#39;s &quot;a unique value&quot; while the second link says it should be a UUID.

If I send either user IDs or generated UUIDs on my backend, how will Google know to link that visitor to an existing visitor session? It seems like I would need to retrieve GA&#39;s internal reference to an existing user.

Any help is appreciated - thanks!


What is the client ID when sending tracking data to google analytics via the measurement protocol?

How to get the first day and the last day of the current year in c#

I&#39;m using rails 4 &amp; ruby 1.9.3 for my application and `fancybox2-rails` gem, but there&#39;s a general problem with asset pipeline. If I run `rake task` for precompile, then everything is fine except for images in `vendor/assets/images` and `../gems/ruby-1.9.3-p327/gems/fancybox2-rails-0.2.1/vendor/assets/images`. Images from these two folders are not being precompiled and eventually I have a problem with dead links to non-existing images. Any suggestions?

Everything goes well in local machine with assets pipeline in Rails 4 and Ruby 2.0. But when deploying to heroku, it is shown that:

       Asset precompilation completed (14.36s)

Heroku seems to compile files but put it in /tmp without any errors. My questions are:

 1. How come Heroku compile assets files to /tmp?
 2. My last solution was to run RAILS_ENV=production bundle exec rake assets:precompile locally, but this generated a manifest-xxxxxx.json in public/assets, rather than manifest.yml, so that heroku doesn&#39;t detect the JSON manifest file. I sorted it out by manually created a yml from the json file and heroku became happy. Has heroku&#39;s approach been outdated?

 

Heroku does NOT compile files under assets pipelines in Rails 4

In Rails 3, gems used exclusively to generate assets in the asset pipeline were properly placed in the `assets` group of the Gemfile:

    ...

    # Gems used only for assets and not required
    # in production environments by default.
    group :assets do
      gem &#39;sass-rails&#39;
      gem &#39;coffee-rails&#39;
      gem &#39;uglifier&#39;
  
      # See https://github.com/sstephenson/execjs#readme for more supported runtimes
      # gem &#39;therubyracer&#39;, :platforms =&gt; :ruby
    end

Now, according to the (still in progress) [upgrade documentation](http://edgeguides.rubyonrails.org/upgrading_ruby_on_rails.html#upgrading-from-rails-3-2-to-rails-4-0):

&gt; Rails 4.0 removed the assets group from Gemfile. You&#39;d need to remove that line from your Gemfile when upgrading.

Sure enough, making a new project with RC1 yields a Gemfile with asset-related gems included by default outside of any group:

    source &#39;https://rubygems.org&#39;

    # Bundle edge Rails instead: gem &#39;rails&#39;, github: &#39;rails/rails&#39;
    gem &#39;rails&#39;, &#39;4.0.0.rc1&#39;

    # Use sqlite3 as the database for Active Record
    gem &#39;sqlite3&#39;

    # Use SCSS for stylesheets
    gem &#39;sass-rails&#39;, &#39;~&gt; 4.0.0.rc1&#39;

    # Use Uglifier as compressor for JavaScript assets
    gem &#39;uglifier&#39;, &#39;&gt;= 1.3.0&#39;

    # Use CoffeeScript for .js.coffee assets and views
    gem &#39;coffee-rails&#39;, &#39;~&gt; 4.0.0&#39;

    # See https://github.com/sstephenson/execjs#readme for more supported runtimes
    # gem &#39;therubyracer&#39;, platforms: :ruby

    ...

Does this mean these gems will now be bundled in production builds by default? If so, why the change of heart? Is Rails 4 moving towards the dynamic generation of assets in production?

Why did Rails4 drop support for &quot;assets&quot; group in the Gemfile

Are we supposed to use something else aside from `image-url` and others in Rails 4? They return different values that don&#39;t seem to make sense. If I have `logo.png` in `/app/assets/images/logo.png` and I do the following, this is what I get:

    image-url(&quot;logo.png&quot;) -&gt; url(&quot;/images/logo.png&quot;) #obviously doesn&#39;t work
    image-path(&quot;logo.png&quot;) -&gt; &quot;/images/logo.png&quot;
    asset-url(&quot;logo.png&quot;) -&gt; url(&quot;/logo.png&quot;)

Of course none of these work because they need at least `/assets` in front.

***UPDATE***: Actually, I just noticed, how do I access images in Rails 4? I have an image at `/app/assets/images/logo.png`. But if I go to any of the following URLs, I still don&#39;t see my image:

    http://localhost:3000/assets/logo.png
    http://localhost:3000/assets/images/logo.png
    http://localhost:3000/logo.png
    http://localhost:3000/images/logo.png

***UPDATE 2***: The only way I can bring up my `logo.png` is by moving it into the `/app/assets/stylesheets` directory and then pulling up:

    http://localhost:3000/assets/logo.png

Rails 4 image-path, image-url and asset-url no longer work in SCSS files

The problem is exactly what the heading says. The javaScript is in the asset pipeline i.e assets/javascripts/myfile.js.coffee In the application.js I have:

    //= require jquery
    //= require jquery_ujs
    //= require turbolinks
    //= require jquery.ui.all
    //= requier twitter/bootstrap
    //= require jasny-bootstrap
    //= require_tree .

This is the coffeescript

    $(document).ready -&gt;
      $(&quot;#close&quot;).click -&gt;
        $(this).parent().parent().slideUp(&quot;slow&quot;)
  


  
      $( &quot;#datepicker&quot; ).datepicker
        dateFormat : &quot;yy-mm-dd&quot;
    

      player_count = $(&quot;#player option&quot;).length


      $(&#39;#btn-add&#39;).click -&gt;
        $(&#39;#users option:selected&#39;).each -&gt;
          if player_count &gt;= 8
            $(&#39;#select-reserve&#39;).append(&quot;&lt;option      value=&#39;&quot;+$(this).val()+&quot;&#39;&gt;&quot;+$(this).text()+&quot;&lt;/option&gt;&quot;)
            $(this).remove()    
          else
            $(&#39;#player&#39;).append(&quot;&lt;option value=&#39;&quot;+$(this).val()+&quot;&#39;&gt;&quot;+$(this).text()+&quot;&lt;/option&gt;&quot;)
            $(this).remove()
            player_count++
    

      $(&#39;#btn-remove&#39;).click -&gt;
        $(&#39;#player option:selected&#39;).each -&gt;
          $(&#39;#users&#39;).append(&quot;&lt;option value=&#39;&quot;+$(this).val()+&quot;&#39;&gt;&quot;+$(this).text()+&quot;&lt;/option&gt;&quot;)
          $(this).remove()
          player_count--
   

      $(&#39;#btn-remove-reserve&#39;).click -&gt;
        $(&#39;#select-reserve option:selected&#39;).each -&gt;
          $(&#39;#users&#39;).append(&quot;&lt;option value=&#39;&quot;+$(this).val()+&quot;&#39;&gt;&quot;+$(this).text()+&quot;&lt;/option&gt;&quot;)
          $(this).remove()
   

      $(&quot;#submit&quot;).click -&gt;
       $(&quot;select option&quot;).prop(&quot;selected&quot;, &quot;selected&quot;)
 
I can see in the source code on the browser that the javaScript has been loaded, but it only works after I reload the page.

I have a Rails 4 application and I am trying to use a custom font.

I have followed many tutorials on this and somehow it&#39;s just not working for my application.

I am using `application.css.less` and have the following declaration:

    @font-face {
        font-family: &#39;HDVPeace&#39;;
        src: font-url(&#39;HDV_Peace.eot&#39;);
        src: font-url(&#39;HDV_Peace.eot?iefix&#39;) format(&#39;eot&#39;),
            font-url(&#39;HDV_Peace.woff&#39;) format(&#39;woff&#39;),
            font-url(&#39;HDV_Peace.ttf&#39;) format(&#39;truetype&#39;),
            font-url(&#39;HDV_Peace.svg#webfont&#39;) format(&#39;svg&#39;);
    }

*Note: I have tried using* `url()` *instead of* `font-url()` *also. The former generates 404 errors on the console, where the latter just doesn&#39;t seem to do anything at all. In the chrome dev tools under resources, the font files are not appearing under the* `assets` *folder, or anywhere*

in my `config/application.rb` I have:

    config.assets.paths &lt;&lt; Rails.root.join(&#39;app&#39;, &#39;assets&#39;, &#39;fonts&#39;)

And in both my `config/environments/development.rb` and `config/environments/production.rb` I have:

    config.assets.paths &lt;&lt; Rails.root.join(&#39;app&#39;, &#39;assets&#39;, &#39;fonts&#39;)
    config.assets.precompile += %w( .svg .eot .woff .ttf)

My font files are located at `app/assets/fonts` and are not contained in a folder below that...

What am I missing?

**UPDATE:**

folder structure
    
    app
    └── assets
        └── fonts
            ├── HDV_Peace.eot
            ├── HDV_Peace.svg
            ├── HDV_Peace.ttf
            └── HDV_Peace.woff

How to use fonts in Rails 4

The default Rails 4 project generator now creates the directory &quot;concerns&quot; under controllers and models. I have found some explanations about how to use routing concerns, but nothing about controllers or models.

I am pretty sure it has to do with the current &quot;DCI trend&quot; in the community and would like to give it a try.

The question is, how am I supposed to use this feature, is there a convention on how to define the naming / class hierarchy in order to make it work? How can I include a concern in a model or controller?

How to use concerns in Rails 4

With Observers officially [removed from Rails 4.0](https://github.com/rails/rails-observers), I&#39;m curious what other developers are using in their place. (Other than using the extracted gem.) While Observers were certainly abused and could easily become unwieldily at times, there were many use-cases outside of just cache-clearing where they were beneficial.

Take, for example, an application that needs to track changes to a model. An Observer could easily watch for changes on Model A and record those changes with Model B in the database. If you wanted to watch for changes across several models, then a single observer could handle that. 

In Rails 4, I&#39;m curious what strategies other developers are using in place of Observers to recreate that functionality. 

Personally, I&#39;m leaning towards a sort of &quot;fat controller&quot; implementation, where these changes are tracked in each models controller&#39;s create/update/delete method. While it bloats the behavior of each controller slightly, it does help in readability and understanding as all the code is in one place. The downside is that there&#39;s now code that is very similar scattered throughout several controllers. Extracting that code into helper methods is an option, but you&#39;re still left with calls to those methods littered everywhere. Not the end of the world, but not quite in the spirit of &quot;skinny controllers&quot; either. 

ActiveRecord callbacks are another possible option, though one I don&#39;t personally like as it tends to couple two different models too closely together in my opinion. 

So in the Rails 4, no-Observers world, if you had to create a new record after another record was created/updated/destroyed, what design pattern would you use? Fat controllers, ActiveRecord callbacks, or something else entirely? 

Thank you.

[starting from Rails 4][1], everything would have to run in threaded environment by default. What this means is all of the code we write **AND** __ALL__ the gems we use are required to be `threadsafe`

so, I have few questions on this:

1. what is NOT thread-safe in ruby/rails? **Vs** What is thread-safe in ruby/rails?
2. Is there a list of gems that _is_ known to be threadsafe or vice-versa?
3. is there List of common patterns of code which are NOT threadsafe example `@result ||= some_method`?
4. Are the data structures in ruby lang core such as `Hash` etc threadsafe?
5. On MRI, where there a [`GVL`/`GIL`][2] which means only 1 ruby thread can run at a time except for `IO`, does the threadsafe change effect us?

There&#39;s a strange issue with Rails 4 on Heroku.  When images are compiled they have hashes added to them, yet the reference to those files from within CSS don&#39;t have the proper name adjusted.  Here&#39;s what I mean.  I have a file called logo.png. Yet when it shows up on heroku it is viewed as:

    /assets/logo-200a00a193ed5e297bb09ddd96afb953.png

However the CSS still states:

    background-image:url(&quot;./logo.png&quot;);

The result: the image doesn&#39;t display.  Anybody run into this?  How can this be resolved?
