Fehler mit verschachtelten Ressourcen

Question

Ich versuche, die verschachtelten Ressourcen rails in Ajax zu verwenden, aber ich bekomme diesen Fehler: Verarbeitung von ListapromoController # als JS erstellen Parameter: {"utf8" => "✓", "detalleprom" => { "Articulo" => "2", "listaprom_id" => "1247", "PromoId" => "1247", "Id" => "1247"}, "commit" => "Detalleprom erstellen", "listaprom_id" => "1245"} 400 Bad Request in 1ms Completed (Active: 0,0 ms)

Action :: ParameterMissing (param fehlt oder der Wert leer ist: listaprom): app/controllers/listapromo_controller.rb: 81 : in listaprom_params' app/controllers/listapromo_controller.rb:31:in erstellen '

das ist meine Indexansicht:

Answer 1

Ich nehme an, Sie den Fehler bekam, wenn dieses Formular abschicken versuchen:

<%= 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%> 

Wenn Sie versuchen, zu aktualisieren listaprom und seine zugehörigen detalleprom, können Sie field_for verwenden und accepts_nested_attributes_for zu Ihrem listaprom Modell hinzufügen. Vergessen Sie nicht, auch Ihre starken Parameter zu ändern. Die Art, wie Sie es hier tun, sendet eine Create Detalleprom Anfrage an ListapromoController. Der Controller versteht die Anforderung und somit den 400-Code nicht.

Das folgende Formular ein detalleprom im Zusammenhang mit @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>
