实现单表继承后损坏的Rails路由

Question

我已经为person类实现了单表继承

class Person < ActiveRecord::Base

end


class Teacher < Person

end

class Student < Person

end

class Outsider < Person

end

而创建人似乎根据form.select中选择的内容创建了Teacher,Student或Person,并添加了type属性.

但是,我似乎打破了路线

<%= link_to'Edit',edit_person_path(@deal)%> | <%= link_to'Back',persons_path%>

它们似乎指向teacher_path,student_path和outsider_path而不是person_path.

路线需要做哪些改变？

Answer 1

首先为您的模型生成控制器...

rails generate controller Persons
rails generate controller Teachers
rails generate controller Students
rails generate controller Outsiders

然后在routes.rb中（rails 3）

resources :persons
resources :teachers
resources :students
resources :outsiders

为您提供 REST 路线

例如

persons GET    /persons(.:format) {:action=>"index", :controller=>"persons"}
new_person GET    /person/new(.:format) {:action=>"new", :controller=>"persons"}
edit_person GET    /persons/:id/edit(.:format) {:action=>"edit", :controller=>"persons"}
person GET    /persons/:id(.:format) {:action=>"show", :controller=>"persons"} 
persons POST   /spersons(.:format) {:action=>"create", :controller=>"persons"}    
person PUT    /persons/:id(.:format) {:action=>"update", :controller=>"persons"}    
person DELETE /persons/:id(.:format) {:action=>"destroy", :controller=>"persons"}
