嵌套资源索引不工作

Question

我有一个嵌套路由appointments和schedules 当我尝试去doctors/1/appointments/或doctors/1/schedules/我得到一个路由错误。对我来说，它看起来像索引页面内的链接错误，但我检查了耙路线，一切似乎都很好。编辑，显示和新操作都可以正常工作。

我在做什么错？

route.rb

Pgranges::Application.routes.draw do 

    root :to => "Doctors#index" 

    resources :doctors do 
    resources :appointments 
    resources :schedules 
    end 

    resources :appointment_steps 
end 

这是我的索引文件：

<h1>Listing appointments</h1> 

<table> 
    <tr> 
    <th>Doctor</th> 
    <th>Adate</th> 
    <th></th> 
    <th></th> 
    <th></th> 
    </tr> 

<% @appointments.each do |appointment| %> 
    <tr> 
    <td><%= appointment.doctor_id %></td> 
    <td><%= appointment.adate %></td> 
    <td><%= link_to 'Show', doctor_appointment_path %></td> 
    <td><%= link_to 'Edit', edit_doctor_appointment_path(appointment) %></td> 
    <td><%= link_to 'Destroy', doctor_appointment, method: :delete, data: { confirm: 'Are you sure?' } %></td> 
    </tr> 
<% end %> 
</table> 

<br /> 

<%= link_to 'New Appointment', new_doctor_appointment_path %> 

和我的控制器看起来像这样：

class SchedulesController < ApplicationController 
    def index 
    @doctor = Doctor.find(params[:doctor_id])  
    @schedules = @doctor.schedules.all 



    respond_to do |format| 
     format.html # index.html.erb 
     format.json { render json: @schedules } 
    end 
    end 

    def show 
    @doctor = Doctor.find(params[:doctor_id])   
    @schedule = @doctor.schedules.find(params[:id]) 

    respond_to do |format| 
     format.html # show.html.erb 
     format.json { render json: @schedule } 
    end 
    end 

    def new 
    @doctor = Doctor.find(params[:doctor_id]) 
    @schedule = @doctor.schedules.new 

    @doctors = Doctor.all 


    respond_to do |format| 
     format.html # new.html.erb 
     format.json { render json: @schedule } 
    end 
    end 

    def edit 
    @doctor = Doctor.find(params[:doctor_id])  
    @schedule = @doctor.schedules.find(params[:id]) 
    end 

    def create 
    @doctor = Doctor.find(params[:doctor_id])  
    @schedule = @doctor.schedules.new(params[:schedule]) 

    if @schedule.save 
     redirect_to doctor_url(@schedule.doctor_id) 
    else 
     render action: 'new' 
    end 


    end 

    def update 
    @schedule = Schedule.find(params[:id]) 

    respond_to do |format| 
     if @schedule.update_attributes(params[:schedule]) 
     format.html { redirect_to @schedule, notice: 'Schedule was successfully updated.' } 
     format.json { head :no_content } 
     else 
     format.html { render action: "edit" } 
     format.json { render json: @schedule.errors, status: :unprocessable_entity } 
     end 
    end 
    end 

    def destroy 
    @schedule = Schedule.find(params[:id]) 
    @schedule.destroy 

    respond_to do |format| 
     format.html { redirect_to schedules_url } 
     format.json { head :no_content } 
    end 
    end 
end 

Answer 1

你应该通过双方的资源（医生和预约）将helpers路由到嵌套资源。另外，你忘记了_path的删除链接。试试这个：

<td><%= link_to 'Show', doctor_appointment_path(appointment.doctor, appointment) %></td> 
<td><%= link_to 'Edit', edit_doctor_appointment_path(appointment.doctor, appointment) %></td> 
<td><%= link_to 'Destroy', doctor_appointment_path(appointment.doctor, appointment), method: :delete, data: { confirm: 'Are you sure?' } %></td> 

UPDATE：

此外，对于新的任命链接：

<%= link_to 'New Appointment', new_doctor_appointment_path(appointment.doctor) %>
