Question

目前我直接访问我的联接表。我这样做的原因是因为我只希望工作人员能够调整status

即将面临

的问题

undefined method order_task_path' for #<#<Class:0x00000009bf62c0>:0x0000000a6d7c70>`

带参数参数：

{"id"=>"1,1"}

我可以根据需要显示联接表。问题是当我尝试在编辑中显示它时。

这是我的ordertask控制器

＆＃13;

class OrdersTasksController < ApplicationController
    before_action :set_status, only: [:show]
    def index
        @orders = Order.all
        #@status = OrderTask.includes(:task,:order).where(order_id: params[:id])
    end
    def edit
        
        @status = OrderTask.find(params[:id])
    end
    def show  
        
    end
    
    
    def update
    respond_to do |format|
      if @status.update(order_params)
        format.html { redirect_to @status, notice: 'Order was successfully updated.' }
        format.json { render :show, status: :ok, location: @order }
      else
        format.html { render :edit }
        format.json { render json: @status.errors, status: :unprocessable_entity }
      end
    end
    end 
    
    private
    # Use callbacks to share common setup or constraints between actions.
   def set_status
       @status = OrderTask.includes(:task).where(order_id: params[:id])
    end
    # Never trust parameters from the scary internet, only allow the white list through.
    def order_params
        params.require(:order_task,:order).permit(:id,:order_id,:status)
    end
    
end

＆＃13;

我的show.html.erb

＆＃13;

<p id="notice"><%= notice %></p>


<table class="table table-hover">
    <tr>
        <td><h4>Order Number : <%= @status.first.order.order_number %></h4>
        </td>
    </tr>
    
    <tr>
        <td>Task
        </td>
        <td>Status:
        </td>
    </tr>
    <tr>
        <% @status.each do |i| %>
        <td><%= i.task.task_name %>
        </td>
        <td><%= i.status %>
        </td>
        <td><%= link_to 'Edit', edit_orders_task_path(i) %></td>
        
    </tr>
    <% end %>
</table>

<%= link_to 'Back', orders_tasks_path %>

＆＃13;

我的_form.html.erb

＆＃13;

<%= form_for(@status) do |f| %>
  <% if @status.errors.any? %>
    <div id="error_explanation">
      <h2><%= pluralize(@status.errors.count, "error") %> prohibited this order from being saved:</h2>

      <ul>
      <% @status.errors.full_messages.each do |message| %>
        <li><%= message %></li>
      <% end %>
      </ul>
    </div>
  <% end %>
<table class="table table-hover">
  
    <tr>
        <td><%= f.label "List of task" %>
        </td>
        <td><%= f.label "Status" %>
        </td>
    </tr>
    <tr>
        <td><%= f.task_id %>
        </td>
        <td><div class="dropdown">
            <%= f.select(:status,['In progress', 'Completed'], {}, {class: "control"})%> </div>
        </td>
        
    </tr>
    <tr>
        <td>
        </td>
        <td><%= f.submit %>
        </td>
    </tr>
</table>


<% end %>

＆＃13;

和我的routes

＆＃13;

resources :orders 
    resources :services
    resources :tasks
    resources :customers
    resources :staffs
    resources :orders_tasks 
    
    root 'staffs#index'

＆＃13;

最后是我的ordertask型号

＆＃13;

class OrderTask < ActiveRecord::Base
    self.primary_key = [:order_id,:task_id]
    self.table_name = "Orders_tasks"
    belongs_to :order
    belongs_to :task
    

end

＆＃13;

希望你们能提出建议或其他方面的帮助。 thx提前。

根据错误消息undefined method order_task_path' for #<#<Class:0x00000009bf62c0>:0x0000000a6d7c70>，url helper方法不存在。

您可以在终端中搜索rake routes以获取所有路线和路线助手。

resources :orders do resources :tasks end 生成以下路线和助手。

order_tasks GET /orders/:order_id/tasks(.:format) tasks#index POST /orders/:order_id/tasks(.:format) tasks#create new_order_task GET /orders/:order_id/tasks/new(.:format) tasks#new edit_order_task GET /orders/:order_id/tasks/:id/edit(.:format) tasks#edit order_task GET /orders/:order_id/tasks/:id(.:format) tasks#show PATCH /orders/:order_id/tasks/:id(.:format) tasks#update PUT /orders/:order_id/tasks/:id(.:format) tasks#update DELETE /orders/:order_id/tasks/:id(.:format) tasks#destroy

resources :orders do resources :orders_tasks end

生成以下路线和助手。

order_orders_tasks GET /orders/:order_id/orders_tasks(.:format) orders_tasks#index POST /orders/:order_id/orders_tasks(.:format) orders_tasks#create new_order_orders_task GET /orders/:order_id/orders_tasks/new(.:format) orders_tasks#new edit_order_orders_task GET /orders/:order_id/orders_tasks/:id/edit(.:format) orders_tasks#edit order_orders_task GET /orders/:order_id/orders_tasks/:id(.:format) orders_tasks#show PATCH /orders/:order_id/orders_tasks/:id(.:format) orders_tasks#update PUT /orders/:order_id/orders_tasks/:id(.:format) orders_tasks#update DELETE /orders/:order_id/orders_tasks/:id(.:format) orders_tasks#destroy
