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.

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.
