Question

我刚刚更新到Rails 3.2，我开始遇到这样的错误：

Started GET "/javascripts/application.js?body=1" for 127.0.0.1 at 2012-02-20 23:25:10 +0800

对于post.js，page.js等也一样......但是所有这些文件都在assets/javascripts文件夹中。

为了解决这个问题我到底需要做些什么？

这就是我包括他们的方式：

 <%= javascript_include_tag "application" %>

application.rb中：

require File.expand_path('../boot', __FILE__)

require 'rails/all'

require "sprockets/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 Sandbox3Devise
  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 = :de

    # 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'
  end
end

development.rb：

Sandbox3Devise::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

  config.action_mailer.default_url_options = { :host => 'localhost:3000' }
end

Answer 1

您从哪个版本升级？ Rails 3.1引入了asset pipeline，一种组织资产的新方式（图像，样式表，javascripts等）。好像你必须做过渡：上面链接的指南是一个很好的起点。

**在config/application.rb中，行require "sprockets/railtie"是否存在？如果没有，你应该添加它。

* * （第二次修改）：因此，您应该javascripts/application.js?body=1而不是assets/application.js?body=1。可以使用config.assets.prefix = "/some_other_path"进行设置。它看起来并不像你粘贴的文件中有所改变，所以这可能仍然不是它，在这种情况下......我放弃了。：P

很抱歉为这个老问题添加一个答案，主要是为了那些会遇到这个问题的人（比如我自己）的利益。

我也遇到过这个问题。我没有升级，我作为rails3应用程序启动了我的应用程序，过了一段时间，出现了这种问题。我认为原因是当我开始搞乱宝石时，例如Faye，bootstrap-wysihtml5等需要app.js和applicaion.css文件中的jquery引用。（这就是它在我的版本控制日志中的显示方式）

无论如何，为了解决这个问题，我刚刚创建了一个新的rails应用程序并复制了app，config，db和gems。这解决了rails服务器正在记录的每个问题，因此它可能是资产管道的错误。我在application.rb中包含了require "sprockets/railtie"行以获得良好的衡量标准，如上所述。

从Rails 3.1升级到Rails 3.2后，JavaScript文件夹中的RoutingError
