如何将特定于应用程序的代码添加到Rails的插件中？

Question

I am using facebooker in one of my applications. I want to add some application specific methods to various classes in it? eg

In facebooker/lib/facebooker/models/user.rb

module Facebooker
  class User
    # I want to add my methods here. for e.g my_method
  end
end

I can not directly put my_method in the plugin itself since I also want to access my models from there. Not defining the methods in plugin code itself will also be helpful when I upgrade.

Answer 1

Somewhere in the file you wish to use my_method, type in, include, or require the following code:

module Facebooker
  class User
    def my_method
        #whatever
    end
  end
end

Ruby will then add my_method to Facebooker's User class before you need to call it.

Answer 2

尝试在您正在使用的模型内部猴子贴上facebooker插件，这样您的编辑只会影响您希望编辑在其中运行的模型内部的代码
