如何在Rails 3中定义自己的路由助手？ [英] How to define own routing helpers in rails 3?

问题描述

我使用polimorphic_path并且它有一些问题。此方法需要一些未定义的路由助手。我如何定义（像常规方法一样）自己的路由助手，将像 model_name_path，model_name_url等那样使用？

I use polimorphic_path and it some buggy. This method require some route helper that not defined. How i can define (like regular method) own route helper wich will be used like "model_name_path, model_name_url etc"?

推荐答案

此解决方案对我有用。

将此代码添加到 config / routes.rb 文件的末尾。确保用应用程序的名称替换 MyApp 。

Add this code to the end of config/routes.rb file. Make sure to replace MyApp with your application's name.

MyApp::Application.routes.named_routes.module.module_eval do
  def model_name_path(*args)
    # Your code here
  end

  def model_name_url(*args)
    # Your code here
  end
end

MyApp::Application.routes.named_routes.instance_eval do
  @helpers += [:model_name_path, :model_name_url]
end

这些自定义方法将在控制器，视图和测试中可用。

These custom methods will be available in controllers, views and tests.
