Answer 1

我是这样解决的，你的方法有问题create_user你需要这样做Artist.objects.create( &nbsp;&nbsp;&nbsp;&nbsp;name=form.cleaned_data["name"], &nbsp;&nbsp;&nbsp;&nbsp;image=form.cleaned_data["image"], )并添加ArtistForm(request.POST,&nbsp;request.FILES)我希望我有所帮助

Answer 2

您还需要提供request.FILES表格。form = ArtistForm(request.POST, request.FILES)
