Rails core - Feb 2013 - My SCSS compiled CSS lacks "/assets" in the generated urls

Running "rake assets:clobber assets:precompile" will generate files
like
"application-xxx.css" with incorrect urls after upgrading to Rails 4.

For example url(/fields/xxx.png) when it should be 
url(/assets/fields/xxx.png). For some unknown reason it worked once in 
development mode, but after running rake assets:clobber I can''t get it 
to work again...

Any ideas why image-url(fields/sprite.gif) is generating 
url(/fields/sprite.gif) instead of url(/assets/fields/sprite.gif)?

It happens both in my staging server (running 1.9.3) and in my dev 
machine (Ruby 2.0.0-p1).

I''m stuck with this enigma.

Any help is greatly appreciated.

Thanks in advance,
Rodrigo.

I think I''ve narrowed down the problem. For some reason this block
isn''t
executed when I run rake assets:precompile:

https://github.com/rails/sprockets-rails/blob/master/lib/sprockets/railtie.rb#L86

ActiveSupport.on_load(:action_view) do...

Maybe that''s because I have a class under "lib" that relies
on
ActionView::Helpers::NumberHelper, and then I require
''action_view''. So,
when the hook is registered ''action_view'' might already be
loaded and
the event won''t be triggered. Just guessing of course as I
couldn''t find
any documentation about how that on_load method works.

Then I''ve written something like this to fix the assets precompilation 
for my application:

def fix_asset_precompiling
     config = Rails.application.config
     Rails.application.assets.context_class.tap do |c|
       c.assets_prefix = config.assets.prefix
       c.digest_assets = config.assets.digest
       c.config = config.action_controller
     end
  end

I''m not sending a pull request because I''m not sure what is
the proper
way of fixing it. But I can tell you that if you replace the line above 
with "begin" it works.

  -   ActiveSupport.on_load(:action_view) do
+ begin

But I don''t know what is the reason for the on_load hook, so I
won''t
change anything. I''d just like to let you know about this problem. This
is a new bug and doesn''t exist on Rails 3.

Best,
Rodrigo.

Open a github issue for the problem; it won''t be addressed otherwise.

I would create an issue if I could replicate the issue in a new 
application, but I couldn''t yet.

If I can isolate the problem I''ll create a new issue.

Ok, I could finally replicate the issue in development mode for a new 
application when I disable the turbolinks gem.

In my application it also happens in production and all other 
environments but at least if this is fixed for development mode it could 
also fix for my other environments.

I''ve created this issue:

https://github.com/rails/rails/issues/9461

Here is an application demonstrating the issue:
