如何从 Rails 中的 gem 覆盖类的方法? [英] How to override a method of a class from a gem in Rails?

问题描述

我需要覆盖一个 gem 类的 find 方法的行为.

I need to override the behavior of the find method of a class from a gem.

这是 gem 中的代码:

This is the code in the gem:

module Youtube
  class Display
    attr_accessor :base
    def find(id, options = {})
      detailed = convert_to_number(options.delete(:detailed))
      options[:detailed] = detailed unless detailed.nil?
      base.send :get, "/get_youtube", options.merge(:youtube_id => id)
    end
  end
end

如何在我自己的 Rails 应用程序的 YoutubeSearch 控制器中覆盖上述 find 方法?

How do I override the above find method in my own YoutubeSearch Controller of my Rails Application?

   def find(id, options = {})
    //Code here     
   end

推荐答案

在 config/initializers 目录中创建一个 .rb 文件，代码如下:

Create a .rb file in config/initializers directory with the following code:

Youtube::Display.class_eval do
  def find(id, options = {})
    # Code here     
  end
end
