问题
EDIT 4, 5 and 6
8 hours in, any more ideas are welcome :) Maybe this bug is already known and solved, but I get the behaviour I described in edit 2&3, when you have this in a .css.erb file in app/assets/stylesheets :
li {
background-image: url(<%= asset_path "logo_80px_80px.png" %>);
}
The problem part seems to be the asset_path method call, but .css.scss also breaks it with:
li {
background-image: url(image-path("logo_80px_80px.png"));
}

ORIGINAL POST
I have a Rails 3.1 application that was serving the application.css file when in production mode. After having some unrelated problems I found out about precompiling the assets using:
bundle exec rake assets:precompile RAILS_ENV=production
My application.css file, pre-compiled to produce: 'application-79d6fafe46c10758d8f5a921f1e55ecd.css' but is now not being served despite being present in the public/assets folder. The application.js file is being served fine (as application-9a36deba94d6308ab9bebe4e30a93959.js). Also I note that this problem first appeared after I created a .css.erb file, as suggested by the article on precompilation.
Any thoughts on what I try to do? I'm going to try undoing the .css.erb file, run precompilation again and see if I get my application.css file served.
EDIT 1
Problem does not come from changing .css file to .css.erb. And the erb works fine. Problem seems to come when the asset_path function is used e.g.:
.button_one {
background-image: url(<%= asset_path "activities/text_editor_toolbar.png" %>);
}
This works to give the correct string e.g.: assets/activities/text_editor_toolbar.png", which shows up in the compiled application-(hash).css file which is served in development but not production mode. This is so weird. :| :@
Edit 2 Okay this just got better, but weirder. Seems if I run it once in production mode, it fails. Run it again in development, then again in production and it'll spend ages and launch the 'Microsoft Console Based Script Host' just like it's precompiling the assets, which from the output it seems like it's doing, before finally rendering the page and serving the application-(hash).css successfully:

. . . :-D & :-o ?
Edit 3
You don't need to run it once in production mode first (i.e. it's actually the act of running in development, that does something to trigger the production mode to (?) re-precompile the assets). After using rake to precompile the assets, it just needs to be run in development mode, request a page (which is necessary), then run in production and requesting home page again is enough for it to trigger what seems like the second precompile.
This has now survived a complete reboot of my machine (win 7-64bit). So I think it's a consistent bug.
Is StackOverflow the best place to continue this discussion or is it best to go on to the Sprocket git-hub page, or something?
回答1:
I had the exact same issue, and solved it by changing this option to true (it is at false by default) in my production.rb file.
# Disable Rails's static asset server (Apache or nginx will already do this)
config.serve_static_assets = true
From what I understand, setting this option to false makes sense if you are running under Apache or nginx, which was not my case.
回答2:
I had this issue the other day and solved it by editing the production.rb file
config.assets.compress = true
config.assets.compile = true
config.assets.digest = true
config.assets.initialize_on_precompile = false
Are the asset settings I ended up with. I precompile my assets, while deploying with capistrano.
Before I edited the asset settings, I had exactly the same issue. The .css was being requested and was compiled into my public/assets folder but the server couldnt find the files.
回答3:
To keep things simple I like to use the .css.scss exstension and use:
li {
background-image: image-url("logo_80px_80px.png");
}
Full reference can be found on Rails Guides under Section 2.2.2.
