rails 模型文件路径 [英] rails model file path

问题描述

如何在 rails 中获取模型文件路径?我想要这样的东西:

How can I obtain model file path in rails? I want something like that:

MyModel.file_path

预期结果:/app/models/my_model.rb

expected result: "/app/models/my_model.rb

可以在 rails 中执行还是我需要从模型名称创建文件名并在模型目录中找到它?

It's possible to do in rails or I need to create file name from models name and find it in models directory?

推荐答案

我认为您必须构建它，但相当简单.

I think you have to build it, but is fairly simple.

这里是:

def model_path
  model_file = self.class.name.split("::").map {|c| c.downcase }.join('/') + '.rb'
  path = Rails.root.join('app/models/').join(model_file)
end
