我尝试将应用程序从 Rails 3.1.3 升级到 Rails 3.2.1，但资产出现问题。
我有这样的错误：
ActionController::RoutingError (No route matches [GET] "/assets/logos/opera_logo.png"):

Rails 没有找到我的所有资源，但我认为它们位于正确的文件夹中（例如 app/assets/images/logos/）。
我按照本指南升级我的系统：http://railscasts.com/episodes/318-upgrading-to-rails-3-2?view=asciicast http://railscasts.com/episodes/318-upgrading-to-rails-3-2?view=asciicast。它在 Rails 3.1 上运行得很好。我没有发现任何其他改变要做。我能做些什么？
这是我的 Gemfile ：
source 'http://rubygems.org'
gem 'rails', '3.2.1'
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
gem 'sqlite3'
# Gems used only for assets and not required
# in production environments by default.
group :assets do
gem 'sass-rails', '~> 3.2.3'
gem 'coffee-rails', '~> 3.2.1'
gem 'uglifier', '>= 1.0.3'
end
gem 'jquery-rails'
# To use ActiveModel has_secure_password
# gem 'bcrypt-ruby', '~> 3.0.0'
# Use unicorn as the web server
# gem 'unicorn'
# Deploy with Capistrano
# gem 'capistrano'
# To use debugger
gem 'ruby-debug19', :require => 'ruby-debug'
group :test do
gem 'capybara', '1.1.2'
gem 'rspec-rails', '2.8.1'
gem 'autotest-rails', '4.1.1'
gem 'spork', '0.8.5'
gem 'factory_girl_rails', '1.4.0'

gem 'authlogic', '3.1.0'
gem 'meta_search', '1.1.3'

这是我的development.rb：
Onopia::Application.configure do
# Settings specified here will take precedence over those in config/application.rb
# In the development environment your application's code is reloaded on
# every request. This slows down response time but is perfect for development
# since you don't have to restart the web server when you make code changes.
config.cache_classes = false
# Log error messages when you accidentally call methods on nil.
config.whiny_nils = true
# Show full error reports and disable caching
config.consider_all_requests_local = true
config.action_controller.perform_caching = false
# Don't care if the mailer can't send
config.action_mailer.raise_delivery_errors = false
# Print deprecation notices to the Rails logger
config.active_support.deprecation = :log
# Only use best-standards-support built into browsers
config.action_dispatch.best_standards_support = :builtin
# Do not compress assets
config.assets.compress = false
# Expands the lines which load the assets
config.assets.debug = true
# Raise exception on mass assignment protection for Active Record models
config.active_record.mass_assignment_sanitizer = :strict
# Log the query plan for queries taking more than this (works
# with SQLite, MySQL, and PostgreSQL)
config.active_record.auto_explain_threshold_in_seconds = 0.5
end
这是我的 application.rb ：
require File.expand_path('../boot', __FILE__)
# Pick the frameworks you want:
require "active_record/railtie"
require "action_controller/railtie"
require "action_mailer/railtie"
require "active_resource/railtie"
require "sprockets/railtie"
# require "rails/test_unit/railtie"
if defined?(Bundler)
# If you precompile assets before deploying to production, use this line
Bundler.require(*Rails.groups(:assets => %w(development test)))
# If you want your assets lazily compiled in production, use this line
# Bundler.require(:default, :assets, Rails.env)
end
module Onopia
class Application < Rails::Application
# Settings in config/environments/* take precedence over those specified here.
# Application configuration should go into files in config/initializers
# -- all .rb files in that directory are automatically loaded.
# Custom directories with classes and modules you want to be autoloadable.
# config.autoload_paths += %W(#{config.root}/extras)
# Only load the plugins named here, in the order given (default is alphabetical).
# :all can be used as a placeholder for all plugins not explicitly named.
# config.plugins = [ :exception_notification, :ssl_requirement, :all ]
# Activate observers that should always be running.
# config.active_record.observers = :cacher, :garbage_collector, :forum_observer
# Set Time.zone default to the specified zone and make Active Record auto-convert to this zone.
# Run "rake -D time" for a list of tasks for finding time zone names. Default is UTC.
# config.time_zone = 'Central Time (US & Canada)'
# The default locale is :en and all translations from config/locales/*.rb,yml are auto loaded.
# config.i18n.load_path += Dir[Rails.root.join('my', 'locales', '*.{rb,yml}').to_s]
config.i18n.default_locale = :fr
# Configure the default encoding used in templates for Ruby 1.9.
config.encoding = "utf-8"
# Configure sensitive parameters which will be filtered from the log file.
config.filter_parameters += [:password]
# Enable the asset pipeline
config.assets.enabled = true
# Version of your assets, change this if you want to expire all your assets
config.assets.version = '1.0'
# Configure generators values. Many other options are available,
# be sure to check the documentation.
#config.generators do |g|
# g.test_framework :rspec, :fixture => false
#end
config.action_mailer.default_url_options = { :host => 'localhost:3000' }
end
end
编辑：一个更好的例子。
我想查看这个文件：
应用程序/资产/javascripts/application.js
当我访问这个网址时：
http://localhost:3000/assets/application.js http://localhost:3000/assets/application.js
我有这个错误：
