Django上傳表單錯誤：'InMemoryUploadedFile'對象沒有屬性'COOKIES'

嗨我是新來的Django我試圖建立一個簡單的上傳應用程序。Django上傳表單錯誤：'InMemoryUploadedFile'對象沒有屬性'COOKIES'

forms.py

from django import forms 

class Song(forms.Form): 
song = forms.ImageField()

models.py

from django.db import models 
class Song(models.Model): 
song = models.ImageField(upload_to='songs')

views.py

def upload(request): 

if request.method == 'POST': 
    form = Song(request.POST, request.FILES) 
    if form.is_valid(): 
     handle_uploaded_file(request.FILES['song']) 
     return HttpResponseRedirect('/done/') 

else: 
    form = Song() 
    return render_to_response('upload.html', { 
    'form': form}, 
    context_instance=RequestContext(request) 
    ) 

def handle_uploaded_file(f): 
    destination = open('/home/fh/Desktop/netz/media/name.txt', 'wb+') 
    for chunk in f.chunks(): 
     destination.write(chunk) 
    destination.close()

模板

<form action="/upload/" enctype="multipart/form-data" method="post">{% csrf_token %} 
{{ form.as_p }} 
<input type="submit" value="Submit" /> 
</form>

當我測試它，我得到這個錯誤。我甚至不知道這意味着什麼。任何人都可以弄清楚我做錯了什麼？

檢查是否覆蓋admin.py中模型的查詢集。像：

def queryset(self, request): 
    qs = super(MainClass, self).queryset(request) 
    return qs.only(field1, field2,...)

然後，請確保將圖像字段包含在queryset中。像：

def queryset(self, request): 
    qs = super(MainClass, self).queryset(request) 
    return qs.only(field1, field2,....,ImageFieldName)
