升级到rails 3.2.1后如何处理供应商/插件

升级到rails3.2.1后，出现此警告：

You have Rails 2.3-style plugins invendor/plugins! Rails 4.0 中将删除对这些插件的支持。将它们移出并将它们捆绑到您的 Gemfile 中，或者将它们作为 lib/myplugin/* 和 config/initializers/myplugin.rb 折叠到您的应用程序中。有关更多信息，请参阅发行说明：http://weblog.rubyonrails.org/2012/1/4/rails-3-2-0-rc2-has-been-released

我将插件移至供应商/插件中目录但我不知道如何编写 config/initializers/myplugin.rb 文件，并且谷歌找不到答案。

我刚刚写了一篇关于此的博客文章：如何将 Simple Rails 2.3 样式插件转换为 Rails 3.2

我刚刚经历过这个，发现你只需要浏览每个插件来检查一些事情：

它是 rubygems 上的 gem 吗？如果是这样，只需将其放入 Gemfile 中并从 vendor/plugins 中删除。
如果没有可用的 gem，或者 gem 已旧，请获取 vendor/plugins 中的文件夹并移动它到 lib/plugins

我遇到的一件事是，您需要手动要求所有这些插件。这是我创建并放置在 config/initializers/plugins.rb 中的初始化程序：

Dir[Rails.root.join('lib', 'plugins', '*')].each do |plugin|
  next if File.basename(plugin) == 'initializers'

  lib = File.join(plugin, 'lib')
  $LOAD_PATH.unshift lib

  begin
    require File.join(plugin, 'init.rb')
  rescue LoadError
    begin
      require File.join(lib, File.basename(plugin) + '.rb')
    rescue LoadError
      require File.join(lib, File.basename(plugin).underscore + '.rb')
    end
  end

  initializer = File.join(File.dirname(plugin), 'initializers', File.basename(plugin) + '.rb')
  require initializer if File.exists?(initializer)
end

我还遇到了某些插件所需的初始化程序的问题，因此我将这些特定的初始化程序移至 lib/plugins/initializers 文件夹。您必须将它们命名为插件的名称，因此 my_plugin 插件的初始化程序必须位于文件 lib/plugins/initializers/my_plugin.rb

希望如此有帮助！

I just went through this and found that you just have to go through each plugin to check a few things:

Is it a gem on rubygems? If so, just stick it in your Gemfile and delete from vendor/plugins
If no gem is available, or the gem is old, take the folder in vendor/plugins and move it to lib/plugins

One thing I ran across is that you then need to require all those plugins manually. Here is the initializer I created and placed in config/initializers/plugins.rb:

Dir[Rails.root.join('lib', 'plugins', '*')].each do |plugin|
  next if File.basename(plugin) == 'initializers'

  lib = File.join(plugin, 'lib')
  $LOAD_PATH.unshift lib

  begin
    require File.join(plugin, 'init.rb')
  rescue LoadError
    begin
      require File.join(lib, File.basename(plugin) + '.rb')
    rescue LoadError
      require File.join(lib, File.basename(plugin).underscore + '.rb')
    end
  end

  initializer = File.join(File.dirname(plugin), 'initializers', File.basename(plugin) + '.rb')
  require initializer if File.exists?(initializer)
end

I also had the problem of initializers I needed for some of the plugins, so I moved those particular initializers into the lib/plugins/initializers folder. You have to name them the name of the plugin, so an initializer for the my_plugin plugin would have to be in the file lib/plugins/initializers/my_plugin.rb

Hope this helps!

其他两个答案都很好并且似乎有效。

但是，如果您的插件由供应商/插件/.../lib 下的单个 .rb 文件组成，并且供应商/插件/.../init.rb 只是一个

require 'pluginname'

那么您只需将单个文件复制到您的 lib 目录并将一个文件添加到 config/initializers 中，该文件需要 'yourpluginname'

这是一个使用acts_as_lated 插件的具体示例，该插件还不是一个 gem。

将vendor/plugins/acts_as_erated/lib/acts_as_erated.rb复制到lib/
使用以下内容创建文件config/initializers/acts_as_erated.rb...
需要“acts_as_lated”
删除供应商/插件/acts_as_erated

both the other answers are good and seem to work.

However if your plugin consists of a single .rb file under vendor/plugins/.../lib and the vendor/plugins/.../init.rb is just a

require 'pluginname'

Then you can simply copy the single file to your lib directory and add a file to config/initializers that does a require 'yourpluginname'

Here is a concrete example using the acts_as_rated plugin which is not a gem yet.

copy vendor/plugins/acts_as_rated/lib/acts_as_rated.rb to lib/
create a file config/initializers/acts_as_rated.rb with the following...
require 'acts_as_rated'
delete vendor/plugins/acts_as_rated
