嵌套资源与轨道

Question

我尝试使用单一模式形式的嵌套资源，我得到这个错误：“没有路由匹配{：行动=>”索引“，：控制器=>”detallepromo“，：listaprom_id = >无}缺少必需的键：[：listaprom_id]“我如何使用没有idparam的嵌套窗体？ https://www.youtube.com/watch?v=2Il7PPhen3o

我的索引视图：

<!--<p id="notice"><%= notice %></p>--> 
<h1>Lista de listapromo</h1> 
<style> 
.container { 
} 

</style> 
<div class="container"> 
    <div class="row"> 
    <div class="text-center"> 
     <!-- Button trigger modal --> 
     <button type="button" class="btn btn-primary btn-lg" data-toggle="modal" data-target="#mynewlistaprom"> 
     Nuevo listaprom 
     </button> 
    </div> 
    </div> 

    <br> 
    <br> 



    <table id="listapromo" class="display"><!--el id listapromo es de datatables referenciado en listapromo.coffe y display class es una clase de datatables--> 
    <thead> 

    <tr><!--active es para sombrear la fila--> 
     <th>ID</th> 

     <th></th> 

    </tr> 
    </thead> 
    <tbody id="container_listapromo"> 
     <%= render @listapromo %><!--carga todos los listapromo--> 
</tbody> 


</table> 
<!-- Modal create action --> 
<%= form_for(@listaprom, remote: true, html: {class: "form-horizontal"}) do |f| %> <!--ajax remote: true--> 
    <div class="modal fade" id="mynewlistaprom" tabindex="-1" role="dialog" aria-labelledby="myModalLabel"> 
    <div class="modal-dialog" role="document"> 
     <div class="modal-content">

      <h4 class="modal-title" id="myModalLabel">Agregar listaprom</h4> 
     </div> 
     <div class="modal-body"> 

      <div class="form-group"> 
      <%= f.label :Lista, "Clave:", class: "control-label col-md-2" %> 
      <div class="col-md-5"> 
       <%= f.text_field :Lista, class: "form-control listaprom_clave" %> 
      </div> 


      </div> 

      <%= f.hidden_field :IdEmpresa, value: current_usuario.empresa_id %> 


     </div> 

     <div class="modal-footer"> 
      <button type="button" class="btn btn-default" data-dismiss="modal" id="mynewlistapromclose">Close</button> 
      <%= submit_tag "Create", class: "btn btn-primary"%> 
     </div> 
     </div> 
    </div> 
    </div> 
<%end%> 
</div> 

我的局部视图（编辑以这种形式我想提出的嵌套资源）

我使用本教程做索引视图中添加和编辑操作

<tr id="listaprom_<%= listaprom.id %>"> 
    <td><%=listaprom.id%></td> 






    <td> 

     <button type="button" class="btn btn-warning btn-xs" data-toggle="modal" data-target="#myupdatelistaprom_<%= listaprom.id %>"> 
      Edit 
     </button> 
     <!--Destroy--> 
     <%= link_to 'Destroy', listaprom, method: :delete, class: "btn btn-danger btn-xs", remote:true %> 



     </td> 


<td class="no" > 
     <!--Modal - update listaprom--> 
    <%= form_for(listaprom, :method => :put, remote: true, html: {class: "form-horizontal"}) do |f| %><!--ajax--> 
    <div nohidden class="modal fade si" id="myupdatelistaprom_<%= listaprom.id %>" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true"> 
     <div class="modal-dialog"> 
     <div class="modal-content"> 
      <div class="modal-header"> 
      <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button> 
      <h4 class="modal-title" id="myModalLabel">Editar listaprom</h4> 
      </div> 

      <div class="modal-body"> 

      <div class="form-group"> 
       <%= f.label :Lista, "Clave:", class: "control-label col-md-2" %> 
       <div class="col-md-5"> 
       <%= f.text_field :Lista, class: "form-control listaprom_clave" %> 
       </div> 


      </div> 

      <%= form_for([@listaprom,@detalleprom], remote: true, html: {class: "form-horizontal"}) do |f| %> <!--ajax remote: true--> 

       <div class="form-group"> 
       <%= f.label :Articulo, "Articulo:", class: "control-label col-md-2" %> 
       <div class="col-md-5"> 
        <%= f.text_field :Articulo, class: "form-control listaprom_clave" %> 
       </div> 
       <%= f.hidden_field :listaprom_id, value:"1341" %> 
       <%= f.hidden_field :PromoId, value:"1341" %> 

       </div> 

      <%end%> 

      </div> 
      <div class="modal-footer"> 
      <button type="button" id="myupdatebutton_<%= listaprom.id %>" class="btn btn-default" data-dismiss="modal">Close</button> 
      <%= submit_tag "Update", class: "btn btn-primary"%> 
      </div> 
     </div> 
     </div> 
    </div> 
    <%end%></td> 
</tr> 

我routhes

resources :listapromo do 
    resources :detallepromo 
    end 

我的模型

class Detalleprom < ActiveRecord::Base 
    self.primary_key = 'Id' 
    belongs_to :listaprom, class_name:"Listaprom", foreign_key: "PromoId" 
end 

class Listaprom < ActiveRecord::Base 
    has_many :detallepromo, class_name: "Detalleprom", foreign_key: "PromoId" 
end 

我控制器

class ListapromoController < ApplicationController 
    before_action :set_listaprom, only: [:show, :edit, :update, :destroy] 

    # GET /listapromo 
    # GET /listapromo.json

    # Never trust parameters from the scary internet, only allow the white list through. 
    def listaprom_params

end 

Answer 1

抱歉无法评论，因为我没有足够的代表。

尝试在您的强参数中允许:listaprom_id。

也可以显示实际的完整错误和detalleprom控制器代码。

从我可以理解的问题是，无论何时detallepromo#Index1或:listaprom_id出于某种原因，您都不会通过:listaprom_id。

同样在一些地方它是Detalleprom和在某些地方它是detallepromo。你能解释一下吗？
