问题 Without a file extension I can't get syntax highlighting to persist. That's not the end of the world, but I'd appreciate having it. Will it break Rails if I rename Gemfile as Gemfile.rb ? 回答1: It looks like you can rename it, but bundler will not automatically find it. However, you can just prepend every bundler command with BUNDLE_GEMFILE=Gemfile.rb and it'll work: BUNDLE_GEMFILE=Gemfile.rb bundle install You might also look at http://gembundler.com/man/bundle-config.1.html -- It mentions a

问题 Because a jQuery plugin I use in my application has direct references to images, I'm trying to turn off asset fingerprinting. So I set config.assets.digest = false in my production.rb, but now none of my image references work at all. /assets/foo.png just returns a blank response. I really don't want to alter the jQuery plugin's code and add erb image helpers, but I'm not sure what else to do.

问题 I have the following setup with my stylesheets in a Rails 3.2 application. I have an application.css file with many styles defined in them, and several other files for more specific styles, like everything to do with the footer is in footer.css .

问题 I am trying to generate an oauth signature for use with Netflix. I have been following their API documentation but have issues when they get to the line that says "If you are using a library, once you have created your base string, it is easy to generate the signature.

问题 In Rails 3 (Sprocket), is there a way to load a javascript file using a url to a remote site? For example, I want something similar to this in your .js file using the require directive, //= require http://example.com/remote_file.js 回答1: No. You can only require files that are inside your application or in gems that your application depend on.
