Plugin not reloading in development mode

I am having a weird problem with a plugin I wrote. What is weird is that I have one other plugin that opens various ActiveRecord classes and it has no problems auto-reloading.

In the plugins init.rb file I have

User.class_eval do
  has_one :reputation
  include Karma 
  alias :rep :reputation
end

If I run it in production mode or in rails console there are no issues. When I run it in development it does load it once, but never again unless I restart the server.

I couldn't find anything special in the other plugin I am using(acts_as_readable) and it opens User in the same manner.

Edit:

I did:

ActiveRecord::Base.class_eval do
  class << self
    def has_karma_values
      has_one :reputation
      alias :rep :reputation
    end
  end
end

in the plugiin's init.rb file and did

class User < ActiveRecord::Base
...
has_karma_values
...
end

And get the same error about has_karma_values not existing. The plugin hasn't been loaded at this point.

What is confusing is that acts-as-readable has no issues at all wit开发者_开发问答h

User.class_eval do
  has_many :readings
end

ActiveRecord::Base.send :include, ActiveRecord::Acts::Readable

but yet mine does.

Here is my complete init.rb file

require 'reputation'
require 'karma_name'
require 'karma_tag'
require 'karma_title'
require 'acts_as_karmable'
require 'karma'
require File.expand_path('../lib/generators/karma_generator', __FILE__)

KarmaTitle.setup 'Default'

ActiveRecord::Base.class_eval do
  class << self
    def has_karma_values
      has_one :reputation
      alias :rep :reputation
    end
  end
end

ActiveRecord::Base.send :include, ActiveRecord::Acts::Karmable

Here is the error /home/david/apps/ruby/lib/ruby/gems/1.9.1/gems/activerecord-3.0.9/lib/active_record/base.rb:1014:inmethod_missing': undefined local variable or method has_karma_values' for #<Class:0x9ad1b24> (NameError)

This should work:

# plugin init.rb
Rails.configuration.to_prepare do
  User.class_eval do
    has_one :reputation
    include Karma 
    alias :rep :reputation
  end
end

The init file is loaded once, you should not access your models from your plugin, it should be the other way around, your init file should probably be like this:

ActiveRecord::Base.class_eval do
  class << self 
    def acts_as_readable
      has_one :reputation
      include Karma
      alias :rep :reputation
    end
  end
end

And at your user.rb file you should do it like this:

class User < ActiveRecord::Base
  acts_as_readable
end

And this should give you the functionality you expect.
