空请求.FILES与Django上传表单 [英] Empty Request.FILES with Django Upload forms

问题描述

尝试使用非常简单的表单将文件上传到新的类实例中。我希望在 request.FILES 中都有这两个文件，但它是空的。我在捆绑的开发者服务器上。

被困在这里，并通过所有相关问题。

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

生成

MultiValueDictKeyError：Keymedia_file'在MultiValueDict中找不到：
{}>

模型

 类WayfinderMap 
寻找地图配置
 
 
 media_file = models.FileField（upload_to =maps，null = True，blank = True ）
 wall_file = models.FileField（upload_to =maps_data，null = True，blank = True）
  

视图

  @login_required 
 def create_map（request，form_class = WayfinderMapForm ，template_name =wayfinder / map / create.html）：
 wayfinder_map_form = form_class（request.user，request.POST或None，request.FILES）
 
如果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（）
返回HttpResponseRedirect（wayfinder_map.get_absolute_url（））
 
返回render_to_response（template_name，{ 
wayfinder_map_form：wayfinder_map_form，
}，context_instance = RequestContext（request）
  

模板

 < form enctype =multipart / form-dataclass =uniForm id =wayfinder_map_formmethod =POSTaction => 
< fieldset class =inlineLabels> 
 {{wayfinder_map_form | as_uni_form}} 
< div class =form_block> 
< input type =hiddenname =actionvalue =create/> 
< input type =submitvalue ={％trans'cre​​ate'％}/> 
< / div> 
< / fieldset> 
< / form> 
  

解决方案

看起来像request.FILES在这里是不必要的案例（好事因为空...）

我修改了这一行

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

for

  wayfinder_map.media_file = wayfinder_map_form.cleaned_data ['media_file'] 
  

它可以工作。不知道什么是正确的方式做事情虽然... -

Trying to use a very simple form to upload a file into a new class instance. I am expecting to have both files in request.FILES but it's empty. I am on the bundled dev server.

Been stuck here and went through all related questions.

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

generates

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

model

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

@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

<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>

解决方案

It seems as request.FILES is not necessary in this case (good thing cause it's empty ...)

I modified this line

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

for

wayfinder_map.media_file = wayfinder_map_form.cleaned_data['media_file'] 

and it works. Not sure what the right way to do thing though... –
