How to deal with vendor/plugins after upgrading to rails 3.2.1

I just wrote a blog post on this: How to Convert Simple Rails 2.3 Style Plugins for Rails 3.2

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!

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.

1. copy vendor/plugins/acts_as_rated/lib/acts_as_rated.rb to lib/

2. create a file config/initializers/acts_as_rated.rb with the following...

   require 'acts_as_rated'

3. delete vendor/plugins/acts_as_rated
