<%= javascript_include_tag "application" %>

给我

<script src="/javascripts/application.js" type="text/javascript"></script>

缺少摘要,我收到以下错误：

cache: [GET /javascripts/application.js] miss
Started GET "/javascripts/application.js" for 127.0.0.1 at 2011-10-03 23:31:36 +0100
ActionController::RoutingError (No route matches [GET] "/javascripts/application.js"):

我在application.rb中尝试过这些设置的变体：

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

#require 'rails/all'
require "action_controller/railtie"
require "action_mailer/railtie"
require "active_resource/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 Blog
  class Application < Rails::Application
    config.autoload_paths += %W(#{config.root}/lib)
    config.encoding = "utf-8"
    config.filter_parameters += [:password]
    config.assets.enabled = true
    config.assets.version = '1.0'
  end
end

和完整的production.rb(减去一些评论)

Blog::Application.configure do
  config.cache_classes = true
  config.consider_all_requests_local       = false
  config.action_controller.perform_caching = true
  config.serve_static_assets = false
  config.assets.compress = true
  config.assets.compile = false
  config.assets.digest = true
  config.i18n.fallbacks = true
  config.active_support.deprecation = :notify
end

我运行了rake资产：预编译任务.

我错过了任何明显的步骤吗？

编辑：一些其他细节：

我的资产位于app / assets文件夹中. app / assets / images,app / assets / javascripts,app / assets / stylesheets等.

我看到我的公共/资产目录中生成的文件包含名称和摘要.

app / assets / javascripts / application.js的确编译成public / assets / application-6ec417a53cb2bdb949966a153a61e7b1.js.它们最终会出现在公共目录中.
