Question

我正在尝试在我拥有的旧版rails应用程序上设置资产管道，以便我可以开始使用CoffeeScript。我正在使用ruby 1.9.3-p327和Rails 3.2.13。我曾经把我的所有JS，CSS和我的图像藏在public/文件夹中。这就是我到目前为止所做的事情 - ＆gt;

我将它们全部移动到app / assets，我添加了JS和CSS调用//= require_tree .的清单文件。

添加了以下宝石

group :assets do
  gem 'coffee-rails'
  gem 'uglifier'
  gem 'sass-rails'
  gem 'therubyracer'
end

删除了除javascript_include_tags

= javascript_include_tag 'https://ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js'

在我的config/application.rb文件

中添加了以下内容

# Enforce whitelist mode for mass assignment.
# This will create an empty whitelist of attributes available for mass-assignment for all models
# in your app. As such, your models will need to explicitly whitelist or blacklist accessible
# parameters by using an attr_accessible or attr_protected declaration.
config.active_record.whitelist_attributes = true

# 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'

在config / environments / development.rb文件集中

# Do not compress assets
config.assets.compress = false

# Expands the lines which load the assets
config.assets.debug = true

我已添加到config / environments / production.rb

# Compress JavaScripts and CSS
config.assets.compress = true

# Choose the compressors to use
# config.assets.js_compressor  = :uglifier
# config.assets.css_compressor = :yui

# Don't fallback to assets pipeline if a precompiled asset is missed
config.assets.compile = false

# Generate digests for assets URLs.
config.assets.digest = true

# Precompile additional assets (application.js, application.css, and all non-JS/CSS are already added)
# config.assets.precompile += %w( search.js )

我重新阅读Asset Pipeline上的部分只是为了看看我是否搞砸了什么。但到目前为止，没有任何资产从app/assets开始，唯一正在运作的是jquery.min.js我通过include_tag进入我尝试删除它并再次尝试没有骰子

我尝试了bundle exec rake assets:clean和bundle exec rake assets:precompile，两者都没有问题。自从为资产添加宝石后捆绑了，每次都重启pow。

我不确定我是否经历过这一切，或者我错过了一步？任何人经历过此之前和提示或线索将非常感激。

你说你删除了所有javascript_include_tag语句。假设您将清单命名为app/assets/javascripts/application.js和app/assets/stylesheets/application.css，则需要在布局中包含这些清单：

<%= stylesheet_link_tag    "application", :media => "all" %>
<%= javascript_include_tag "application" %>

否则，Rails不知道加载您的清单文件

此外，您不应该在开发中使用rake assets:precompile。如果这样做，那么无论何时更改JS / CSS文件，您都必须在更改显示之前重新编译资产。
