如何在Rails中动态调用路由助手？ [英] How to dynamically call routes helper in rails?

问题描述

例如，我构造了一个名为 new_work_path的字符串，现在我想将该助手称为方法。

For example, I have constructed a string called "new_work_path", now I want to call that helper as a method.

我尝试了 send（ new_work_path，vars）并从许多对象调用相同的发送。但是我认为我找不到合适的对象来调用这些助手。

I've tried send("new_work_path", vars) and calling the same send from many objects. But I don't think that I've found the right object to call these helpers.

要做 object.send（ new_work_path， vars），我应该寻找什么对象？

To do object.send("new_work_path", vars), what object should I be looking for?

我试图在线寻找该对象一段时间，但找不到任何东西。如果有人可以照亮它，那就太好了！

I've tried to look for this online for a while but couldn't find anything. If anyone can shine some lights on this one, it would be great!

谢谢！

推荐答案

尝试 Rails.application.routes.url_helpers.send（...）

编辑：

作为Larry Gebhardt 提到 url_helpers 模块不再被缓存。

As Larry Gebhardt mentioned the url_helpers module is no longer being cached.

另一种解决方法是：

cached_helpers = Class.new do
  include Rails.application.routes.url_helpers
  include Rails.application.routes.mounted_helpers
end.new

cached_helpers.send(...)
