我该如何猴子修补Jekyll扩展或插件? [英] How do I monkey-patch a Jekyll extension or plugin?

问题描述

我想重写如下所示的gem方法(Jekyll扩展名):

I'd like to override a gem method (a Jekyll extension) that looks like this:

文件: lib/jekyll-amazon/amazon_tag.rb .

module Jekyll
  module Amazon
    class AmazonTag < Liquid::Tag
      def detail(item)
...
      end
    end
  end
end
Liquid::Template.register_tag('amazon', Jekyll::Amazon::AmazonTag)

我已经将具有相同结构的代码放置在项目中的 config/initializers/presentation.rb _plugins/presentation.rb文件夹中.如果我将方法detail的名称更改为新名称，则它可以工作，但无法获取它来覆盖名称detail. 我做错了什么?

I have placed code with the same structure in my project in the folder config/initializers/presentation.rb _plugins/presentation.rb. If I change the name of the method detail to a new name, it works, but I can't get it to override the name detail. What have I done wrong?

(注意:在jekyll-amazon gem的0.2.2版中，detail方法是私有的；我在本地更改了此方法，因此该方法不再是私有的.)

(Note: In version 0.2.2 of the jekyll-amazon gem, the detail method is private; I have changed this locally so that the method is no longer private.)
