Django：ImageField未知字段

Question

I currently have a django project I am working on and I extended the user profile successfully, however I would like to allow the user to have a profile picture so I added the following code: Models.py:

profile_pic = models.ImageField(upload_to='img/profile/%Y/%m/')

and in my forms.py

class UserProfileForm(forms.ModelForm):

    class Meta:
        model = UserProfile
        fields = ('profile_pic')

and here is the code for my views:

@login_required
def user_profile(request):
    if request.method == 'POST':
        form = UserProfileForm(request.POST, request.FILES, instance=request.user.profile)
        if form.is_valid():
            form.save()
            return HttpResponseRedirect('/accounts/profile')
    else:
        user = request.user
        profile = user.profile
        form = UserProfileForm(request.POST or None, instance=profile)

    args = {}
    args.update(csrf(request))

    args['form'] = form

    return render_to_response('profile.html', args)

However when I go to the profile page now, I am presented with the following:

Django Version: 1.6.2

Exception Type: FieldError

Exception Value:

Unknown field(s) (profile_pic) specified for UserProfile

Any ideas? I am pretty new to the django framework. Thank you

fields = ('profile_pic')逗号不必是fields = ('profile_pic',)
