django image的MultiValueDictKeyError文件上传

我花了很多时间试图解决这个问题 - 阅读Django文档,咨询表格但没有得到任何满意的结果.所以请耐心等待我.我试图从我的html模板上传一个图像文件.这是我的html表单

{% csrf_token %}
  
 



 

文件上传正确,我能够在HTML中看到上传的图像文件.

在我的views.py,

def upload_image(request, frameslug):

frame= VTryON.objects.get(slug=frameslug)
if request.method == 'POST':
    form = ImageUploadForm(request.POST, request.FILES)
    print "FILES", request.FILES
    if form.is_multipart():
        save_file(request.FILES['image'])
        return HttpResponseRedirect('Successful')
    else:
        return HttpResponse('Invalid image')
else:
    form = ImageUploadForm()
return render_to_response('dummy.html', {'form': form})


def save_file(file, path=''):
    ''' Little helper to save a file
    '''
    filename = file._get_name()
    fd = open('%s/%s' % (MEDIA_ROOT, str(path) + str(filename)), 'wb')
    for chunk in file.chunks():
        fd.write(chunk)
    fd.close()

在我的forms.py,

from django import forms
class ImageUploadForm(forms.Form):   
image = forms.ImageField(label='Select a file', help_text='max. 20 megabytes')

当我运行我的代码时,我收到此错误

MultiValueDictKeyError at /dummy/fr1234/

我的view.py中的print语句显示了这一点

FILES ]}>

这是追溯

Traceback:

  112.                     response = wrapped_callback(request, *callback_args, **callback_kwargs)

我知道enctype应该是multipart/form-data因为我已经在教程中阅读了它.另外,我没有在models.py中使用任何字段来存储上传的图像.相反,我想直接将它保存到thrIA MEDIA_URL位置.可能会出现问题吗？请帮忙.这让我很长时间了.提前致谢.
