问题 I just upgraded my rails app to 3.1 and I'm making use of the new asset pipeline. With the pipeline in place it's imperative that any static references made in your application utilize the rails helper methods, ie, asset_path(...), img_tag(), etc.... Here's the question, how do I fix the static references in my css files? 回答1: In Rails' SASS files, there's an image-url() function you can use like so: .page { background: #eee image-url('somefile.png'); } Rails will look for that file in all

问题 I'm working on a Rails 3.1.0 app that needs to have ssl in some pages depending on the user. I setted config.force_ssl to false in config/enviroments/staging.rb. Added a before filter that decides whether or not to redirect to http. The redirect works in development if I clean the cache. The thing is in staging, it results in a redirect loop.

问题 I have a Rails 3.1 app running in production using Nginx and Unicorn. And for some reason, my custom 404 and 500 html error pages are not showing. Instead I'm getting the actual error message ("Routing Error", for example). In my production.rb file, I have config.consider_all_requests_local = false And on the same server with a nearly identical configuration, I have a 'staging' site that works just fine. The only difference, as far as I can tell, is that the production one has SSL while the

问题 May I ask you how to make rails web design more efficient? Is compass plus blueprint the perfect match? Is the current version of compass support rails3.1 Are there any other frameworks that will make rails web deign easier? Thanks 回答1: Definitely a framework like compass is awesome, it includes a lot of helpers, and provides a good solid base. For form-styling I would recommend using a gem like [formtastic][1], which not only greatly simplifies making forms, but also provides a standard css
