Question

您好我是Django的新手我正在尝试构建一个简单的上传应用程序。

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>

当我测试它时，我收到此错误。我甚至都不知道这意味着什么。谁能弄清楚我做错了什么？

检查是否在admin.py中覆盖模型的查询集。像：

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

然后，请确保在查询集中包含图像字段。像：

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