python - 更新用户个人资料时 upload_to 不起作用？

Question

当我的用户创建个人资料时，他们的图像保存得很好，但当他们更新它时，图像不会保存。我也不知道如何提取图片以便他们在更新之前可以看到它。

这是表格:

class UpdateProfileForm(forms.ModelForm):
    city = models.ForeignKey(City)

    class Meta:
        model = UserProfile
        fields = ('city', 'profilepic')

    def save(self, commit=True):
        profile = super(UpdateProfileForm, self).save(commit=False)

        if commit:
            profile.save()
        return profile

这是 View :

def updateprofile(request):



if request.method == 'POST':
    update_user_form = UpdateUserForm(request.POST, instance=request.user)
    update_profile_form = UpdateProfileForm(request.POST, request.FILES, instance=request.user.profile)

if update_user_form.is_valid() and update_profile_form.is_valid():
    update_user_form.save()

    '''************************************************'''
    profile = update_profile_form.save(commit=False)

    if 'profilepic' in request.FILES:
        profile.profilepic = request.FILES['profilepic']

    profile.save()

    '''************************************************'''


    return HttpResponseRedirect(reverse('index'))
else:
    update_user_form = UpdateUserForm(instance=request.user)
    update_profile_form = UpdateProfileForm(instance=request.user.profile)


return render(request, 'updateprofile.html', {'update_user_form' : update_user_form, 'update_profile_form' : update_profile_form})

这是模型:

# this is model for user
class UserProfile(models.Model):
    user = models.OneToOneField(User, related_name='profile')

    hobbies = models.ManyToManyField(Hobby)
    languages = models.ManyToManyField(Language)

    profilepic = models.ImageField(upload_to='static/images/Profile Pictures', blank=True)
    city = models.ForeignKey(City)
    slug = models.SlugField(unique=True)

    average_rating = models.IntegerField(default=0)
    ratings_count = models.IntegerField(default=0)

    def save(self, *args, **kwargs):
        # Uncomment if you don't want the slug to change every time the name changes
        self.slug = slugify(self.user.username)
        super(UserProfile, self).save(*args, **kwargs)

    def __unicode__(self):
        return self.user.username

谢谢。

将 request.FILES 添加到表单中:

update_profile_form = UpdateProfileForm(request.POST, request.FILES,
                                        instance=request.user)

默认情况下，django 不包含 request.POST 中的文件

此外，我认为 UserProfile 模型的实例应该是 request.user.profile 而不是 request.user 或者我在这里遗漏了一些东西？

按照 django-docs 的说明进行操作
