嵌套资源的错误

Question

我正在尝试在ajax中使用rails嵌套资源，但我收到此错误：ListapromoController处理#create as JS   参数：{＆＃34; utf8＆＃34; =＆gt;＆＃34;✓＆＃34;，＆＃34; detalleprom＆＃34; =＆gt; {＆＃34; Articulo＆＃34; =＆gt;＆＃34 ; 2＆＃34;，＆＃34; listaprom_id＆＃34; =＆gt;＆＃34; 1247＆＃34;，＆＃34; PromoId＆＃34; =＆gt;＆＃34; 1247＆＃34;，＆＃34; Id＆＃34; =＆gt;＆＃34; 1247＆＃34;}，＆＃34;提交＆＃34; =＆gt;＆＃34;创建Detalleprom＆＃34;，＆＃34; listaprom_id＆＃34; =＆gt;＆ ＃34; 1245＆＃34;} 在1ms内完成400 Bad Request（ActiveRecord：0.0ms）

ActionController :: ParameterMissing（param丢失或值为空：listaprom）：   app / controllers / listapromo_controller.rb：81：在listaprom_params' app/controllers/listapromo_controller.rb:31:in创建＆＃39;

这是我的索引视图：

Answer 1

我认为您在尝试提交此表单时遇到错误：

<%= form_for([@listaprom,@detalleprom],:url => {:listaprom_id => 1245},  remote: true, html: {class: "form-horizontal"}) do |d| %> <!--ajax remote: true-->
          <div class="form-group">
            <%= d.label :Articulo, "Articulo:", class: "control-label col-md-2" %>
            <div class="col-md-5">
              <%= d.text_field :Articulo, class: "form-control listaprom_clave" %>
            </div>
            <div class="actions">
            </div>
            <%= d.hidden_field :listaprom_id, value: listaprom.id %>
            <%= d.hidden_field :PromoId, value: listaprom.id %>
            <%= d.hidden_field :Id, value: listaprom.id %>

            <%= d.submit %>
          </div>

        <%end%>

如果您尝试更新listaprom及其关联的detalleprom，则可以使用field_for并将accepts_nested_attributes_for添加到listaprom模型中。不要忘记修改你的强力params。您在此处执行此操作的方式会向Create Detalleprom发送ListapromoController个请求。控制器不理解请求，因此不理解400代码。

以下表单将创建与detalleprom

相关联的@listaprom

<%= form_for @listaprom, remote: true do |d| %>
(your code from @listaprom)
  <%= d.field_for :detalleprom do |dd| %>
    <%= dd.label :Articulo %>
    <%= dd.text_field :Articulo %>
   (rest of your code for detalleprom)
  <% end %>
<%end>
