使用 Django 上传表单清空 Request.FILES

try 使用非常简单的表单将文件上载到新的类实例中.我希望这两个文件都是request.FILES号的，但它是空的.我在Bundle 的开发服务器上.

我被困在这里，问了所有相关的问题.

wayfinder_map.media_file = request.FILES['media_file'] 

生成

MultiValueDictKeyError: "Key 'media_file' not found in MultiValueDict: {}>"

model个

class WayfinderMap(models.Model):
    """ Way-finding Map Config"""


    media_file = models.FileField(upload_to="maps", null=True, blank=True) 
    wall_file = models.FileField(upload_to="maps_data", null=True, blank=True) 

view个

@login_required
def create_map(request, form_class=WayfinderMapForm, template_name="wayfinder/map/create.html"):
wayfinder_map_form = form_class(request.user, request.POST or None, request.FILES)

    if wayfinder_map_form.is_valid():
        wayfinder_map = wayfinder_map_form.save(commit=False)
        wayfinder_map.media_file = request.FILES['media_file']
        wayfinder_map.data_file = request.FILES['data_file']
        wayfinder_map.creator = request.user
        wayfinder_map.save()
    return HttpResponseRedirect(wayfinder_map.get_absolute_url())

return render_to_response(template_name, {
    "wayfinder_map_form": wayfinder_map_form,
}, context_instance=RequestContext(request))

template个

<form enctype="multipart/form-data" class="uniForm" id="wayfinder_map_form" method="POST" action="">
        <fieldset class="inlineLabels">
            {{ wayfinder_map_form|as_uni_form }}
            <div class="form_block">
                <input type="hidden" name="action" value="create" />
                <input type="submit" value="{% trans 'create' %}"/>
            </div>
        </fieldset>
    </form>
