问题 Sprockets seems to make an error in determining the logical_path of my javascript assets (except for application.js). It prepends "../javascripts" to the path and so my references are wrong and the application.js file won't precompile. I'm using Rails Thin server on Windows. Gemfile: source 'http://rubygems.org' gem 'rails', '3.1.3' gem 'eventmachine', '1.0.0.beta.4.1' gem 'thin' gem 'mysql' gem 'win32-open3-19' gem 'paperclip', '2.3.8' gem 'jsmin' gem 'will_paginate' gem 'jquery-rails' #

问题 Background: I'm building an app that lets users create their own website (e.g., mywebsite.alexlod.com) Each website owner is affiliated with me, so I'll trust them to write their own rails code Each website should have default controllers and views, except when one of these owners creates their own Here's how I envision controllers working: I'm thinking that what's in app/controllers/ will be the default, but when a file is specified in a <subdomain> top-level directory, that file will take

When I hit http://127.0.0.1:3000/book/list , I am getting this error: No route matches [GET] "/book/list"** Here's config/routes.rb : Ravi::Application.routes.draw do # The priority is based upon order of creation: # first

问题 Using this question and railscast 63 I've got my articles routed to articles/article_permalink. I'd like them to be accessible without the model name in the url so my-domain.com/article_permalink routes directly to the article. I'd only want this to happen on the show action. Is this possible? 回答1: I think you need something like ...

问题 I'm working with Rails 3.1's asset pipeline and although it seems to work flawlessly in my development environment on my localhost, I'm having huge issues with it on engine yard.

问题 Although the title of the question is very similar to a number of previous ones, my issue seems different. Briefly, the first item in the js manifest is included twice. Here's the whole of my /app/assets/javascript/application.js file in a Rails 3.1 application: //= require jquery //= require jquery-ui //= require jquery_ujs //= require autocomplete-rails //= require utilities And here's a snippet of the rendered page's source: <script src="/assets/jquery.js?body=1" type="text/javascript"><

问题 I'm using STI subclasses and want to direct to different views for the different subclasses.
