polymorphic_path无法生成正确的路径 [英] polymorphic_path not generating correct path

问题描述

我正在尝试使用名为polymorphic_path的rails方法，但网址错误. 我与学生和房东的多态性关联，他们都是通过可使用的用户.

I am trying to user a rails method called polymorphic_path but I am getting the wrong url. My polymorphic association is with Students and Landlords who are both Users through userable.

这是我的模特:

class User < ActiveRecord::Base
  belongs_to :userable, polymorphic: true
end

class Student < ActiveRecord::Base
  has_one :user, :as => :userable
end

class Landlord < ActiveRecord::Base
  has_one :user, :as => :userable
end

我有一个名为current_user的变量，用于保存User对象.以下行:

I have a variable called current_user holding the User object. The following line:

<%= link_to "Profile", polymorphic_path(current_user) %>

为我提供了网址"users/22"，而不是返回学生/房东的网址.

gives me the url "users/22" instead of returning the Student/Landlord url.

这是我的route.rb文件，如果有帮助的话.

Here is my routes.rb file if that helps..

resources :users
resources :students
resources :landlords

我要去哪里错了? 谢谢！

Where am I going wrong? Thanks!

推荐答案

好，知道了！而且解决方案非常痛苦……

Ok, I got it! And the solution was painfully obvious...

<%= link_to "Profile", polymorphic_path(current_user.userable) %>
<%= link_to "Edit", edit_polymorphic_path(current_user.userable) %>
