I try to upgrade my application from rails 3.1.3 to rails 3.2.1 and I have a problem with assets.

I have this kind of error :

ActionController::RoutingError (No route matches [GET] "/assets/logos/opera_logo.png"):
  actionpack (3.2.1) lib/action_dispatch/middleware/debug_exceptions.rb:21:in `call'

  /usr/lib/ruby/1.9.1/webrick/server.rb:183:in `block in start_thread'

Rails don't find all my assets but I think than they are in the right folder (app/assets/images/logos/ for example).

I followed this guide for upgrade my system : http://railscasts.com/episodes/318-upgrading-to-rails-3-2?view=asciicast. It was running very well with rails 3.1. I don't find any other change to do. What can I do?

This is my 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 'email_spec', '1.2.1'
  gem 'cucumber-rails', '1.2.1'
  gem 'launchy', '2.0.5'
  gem 'pickle', '0.4.10'
  gem 'database_cleaner', '0.7.0'
  gem 'simplecov', '0.5.4'
  gem 'simplecov-rcov', '0.2.3'
  gem "mocha", '0.10.0'
  gem 'capybara-firebug', '0.0.10'
  gem "prawn", '0.8.4'
end

group :development do
  gem "nifty-generators", '0.4.6'
end

gem 'active_reload', '0.6.1'
gem "galetahub-simple_captcha", '0.1.3', :require => "simple_captcha"
gem 'authlogic', '3.1.0'
gem 'meta_search', '1.1.3'
gem 'naive_bayes', :git => 'git://github.com/reddavis/Naive-Bayes.git'

This is my 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

And this is my 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

Edit: a better example.

I want to view this file :

app/assets/javascripts/application.js

When I go to this url :

http://localhost:3000/assets/application.js

And I have this error :

Started GET "/assets/application.js" for 127.0.0.1 at 2012-02-06 17:04:38 -0500
Served asset /application.js - 404 Not Found (1ms)

Thanks a lot and have a nice day.

I hit a similar problem that I resolved by removing the active_reload gem.
