Question

在def中列出了一个表中的文章，其中包含我的模型表单的inputtext，RequestEditForm，每篇文章旁边的输入，以及一个保存inpuText保存量的按钮。我的问题是该按钮什么都不做，因此它不会在数据库中保存输入的数量。

    def ListAll(request, id_especialidad):
       especialidad = Especialidad.objects.get(id=id_especialidad)
    if request.method == 'GET':
      user = request.user
    if user.is_superuser:
       pedido = Pedido.objects.filter(especialidad=especialidad)
       form = PedidoEditForm()
    if form.is_valid():
       form.save()
      pedido.estado = 'pendiente'
      pedido.fecha_pedido = datetime.now()
      pedido.save()

return render（request，'admindata.html'，locals（），{'form'：form}）

      <section id="contenido">
     <div class="container" style="margin:50px auto width="100%"">
    <form id="myform" method="post">
    <table id="example" class="table table-border table-striped table-hover">
        <thead>
            <tr> 
                <td>Servicio</td>
                <td>Cod experto</td>
                <td>Nombre</td>
                <td>stock</td>
                <td>Cantidad</td>
                <td>Fecha Pedido</td>
                <td>Estado</td>
                <td>Ingresar</td>
                <td></td>

            </tr>
        </thead>
        <tfoot>
            <tr>
                <td>Servicio</td>
                <td>Cod experto</td>
                <td>Nombre</td>
                <td>stock</td>
                <td>Cantidad</td>
                <td>Fecha Pedido</td>
                <td>Estado</td>
                <td></td> 

            </tr>
        </tfoot>
        <tbody>
    {% if pedido  %}
    {% for ped in pedido  %}
            <tr>
                <td>{{ ped.especialidad.nombre }}</td>
                <td>{{ ped.articulo.cod_experto }}</td>
                <td>{{ ped.articulo.nombre }}</td>
                <td>{{ ped.articulo.stock }}</td>
                <td>{{ ped.cantidad }}</td>
                <td>{{ ped.fecha_pedido }}</td>
                <td>{{ ped.estado }}</td>
                <td>{% csrf_token %}
                    {{form.as_p}}</td>
                <td></td>
            </tr>
    {% endfor %}
    {% endif %}
       </tbody>
       </table>
       </form>

 $(document).ready(function (){
 var table = $('#example').DataTable({

  'columnDefs': [
     {
        'targets': 0,
     }
  ],
  });

  table.column(7).every( function () {

  var column = this;
   var select = $('<input type="submit" form="myform" class= "btn btn-      success" value="Guardar">')
  .appendTo($(column.footer()).empty())
  .on('change', function() {
    var val = $.fn.dataTable.util.escapeRegex(
      $(this).val()
    );

    column
      .search(val ? '^' + val + '$' : '', true, false)
      .draw();
  });

column.data().unique().sort().each(function(d, j) {
  select.append('<option value="' + d + '">' + d + '</option>')
});

});

});

因为按钮不起作用，我也缺乏，我有以下错误：用户警告：

       A {% csrf_token %} was used in a template, but the context did not    provide the value.  This is usually caused by not using RequestContext.
     " A {% csrf_token %} was used in a template, but the context " help me pls!

Answer 1

而不是render_to_respoonse使用render这样：

return render(request, template, locals())

此外，您在表单外还有一个submit按钮！

您应该将其放在<form></form>内，或者在<input> id of the form where it belongs中定义。像这样：

<input type="submit" form="myform" class= "btn btn-success" value="Guardar">

表单输入模板无法保存
