嵌套资源中的索引不起作用

Question

我有一个嵌套的路由，appointments和schedules当我试图去doctors/1/appointments/或doctors/1/schedules/时，我得到一个路由错误。对我来说，它看起来像有一个错误与索引页内的链接，但我检查耙路线，一切似乎都很好。编辑，显示和新建操作运行良好。

我做错了什么?

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 %>

和我的控制器是这样的:

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

您应该将这两个资源(医生和预约)传递给嵌套资源的路由帮助器。此外，您忘记了删除链接的路径。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>

更新:

另外，对于新的约会链接:

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