我正在使用 Django 1.5.2、jQuery v1.9.0 和 POSTGRESQL 9.1。

我正在使用 ajax 发送表单，但 requst.FILE 为空，imgen 未发送。

这是我的文件。

模型.py

class Evento(models.Model):
    nombre            = models.CharField(max_length=16)
    def __unicode__(self):
        return self.nombre 

class Imagen(models.Model):    
    def url(self,filename):
        ruta = "MultimediaData/Evento/%s/%s"%(self.evento.id,str(filename))
        return ruta
    evento = models.ForeignKey(Evento)
    photo = models.ImageField(upload_to=url)

    def __unicode__(self):
        return str(self.photo)

URSL.py

urlpatterns = patterns('CasadeAna.apps.home.views',        
        url(r'^addevento/$','addevent_view',name='event_add'), 
        url(r'^editevento/(?P<idevento>.*)/$','editevent_view',name='event_edit'), 
)

视图.py

def editevent_view(request,idevento):

        if request.method == 'GET' and request.is_ajax():
            formulario = FormImagen()
            ctx = {'form':formulario}
            return render_to_response('home/event/imagenform.html',ctx,context_instance=RequestContext(request))

        elif request.method == 'POST' and request.is_ajax():
            print 'dasd'
            print request.POST
            print request.FILES 
            print 'dasd'
            formulario =  FormImagen(request.POST,request.FILES)

            if formulario.is_valid():
                formulario.save()
                return HttpResponse('very good')         
            else:
                ctx = {'form':formulario}
                return render_to_response('home/event/imagenform.html',ctx,context_instance=RequestContext(request))

        elif request.method == 'GET':
            evento = Evento.objects.get(id=idevento)
            ctx = {'evento':evento}
            imagen = Imagen.objects.filter(evento=evento)
            return render_to_response('home/event/editEvent.html',ctx,context_instance=RequestContext(request))

HTML

形式

imageform.html

<form id="formulario" method="POST" enctype="multipart/form-data">
        {% csrf_token %}
        {{form.as_p}}
        <button type="submit"class="btn btn-primary" onClick="enviar(this);">Guardar</button>
        <button type="reset" class="btn btn-primary">Limpiar</button>
</form>

编辑事件.html

 {% extends 'base.html' %}
{% block menu %}
{% endblock %}
{% block  content %}
<div style="height:100%;"  align="left" >
    <h1 class="muted"> Editar Imagenes </h1>
  <h2>{{evento.nombre}}</h2>
    <div id="imagenes">
        <div id="menu" >
            <button class="btn" onClick="subirImagen(this);">Agregar Imagen <i class="icon-plus"></i></button>
        <div>           
        <div id="contenedor">
            <ul class="thumbnails">
            {% if  imagen %}
                {% for i in imagen %}
                     <li class="span4">
                        <img data-src="{{i.photo}}" alt="">
                    </li>
                {% endfor %}
            {% endif %}
        </ul>
        </div>
    </div>
 </div>
{% endblock %}
{% block js %}
 <script type="text/javascript">
    //pedir formulario para subir una imagen 
    function subirImagen(e)
    {
        $.ajax({
              url: '/editevento/14/',
              type: 'GET',
              dataType: 'html',
              success: function(datos){
                   $('#contenedor').empty();
                   $('#contenedor').append(datos);
                }
            });
    }
  function enviar(e)
  {
        $('#formulario').submit(function(evento){
            evento.preventDefault();
            var datos_formulario = $(this).serialize();        
            alert('event444os');
            $.ajax({
                url: '/editevento/14/',
                data: datos_formulario,
                type: 'POST',
                dataType: 'html',
                processData:false,
                cache:false,
                success: function(datos){
                    $('#contenedor').empty();
                    $('#contenedor').append(datos);
                }
            });

您不能发布这样的文件。看看这个问题：如何异步上传文件？或者这个问题：jQuery ajax post file field
