更新表格未提交

Question

我正在尝试使用 fbv 更新模型的字段，并且我也为这些字段创建了不同的表单。但是，无论如何我都无法提交表格。我认为问题出在图像字段上，并且表单无法呈现为有效。有解决办法吗？

models.py

  class UserProfile(models.Model):
      user = models.OneToOneField(User,on_delete=models.CASCADE, default=None, null=True)
      role = models.CharField(max_length=50, choices=Roles)
      verified =models.BooleanField(default = False,blank=True)
      photo = models.ImageField(upload_to='images', blank=True, default='default/testimonial2.jpg')
      slug = models.SlugField(unique=False, blank=True)

      def save(self, *args, **kwargs):
         self.slug = slugify(self.user.username)
         super(UserProfile, self).save(*args, **kwargs)

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

       def get_absolute_url(self):
            if (self.verified==True):
               return reverse("NewApp:mail", kwargs={'pk': self.pk})
            else:
                return reverse("NewApp:userlist")

views.py

  def UserUpdateView(request,slug):
     object = User.objects.get(username=request.user)
     user_form = UserUpdateForm(instance=object)
     obj = UserProfile.objects.get(slug=request.user)
      profile_form = UserProfileForm(instance=obj)

      if user_form.is_valid() and profile_form.is_valid():
          user_form.save()
          profile_form.save()
          return redirect('NewApp:logindex')

       return render(request, 'NewApp/userprofile_form.html',
              {'user_form': user_form,
               'profile_form': profile_form,})

forms.py

 class UserUpdateForm(forms.ModelForm):
    class Meta():
        model = User
        fields = ('first_name','last_name','email')


class UserProfileForm(forms.ModelForm):
    class Meta():
        model = UserProfile
        fields = ('photo',)

在 POST 请求的情况下，您不要使用 request.POST 和 request.FILES 构造表单。你应该像这样实现：

def UserUpdateView(request,slug):
    user = request.user
    profile = UserProfile.objects.get(user=user)
    if request.method == 'POST':
        user_form = UserUpdateForm(request.POST, request.FILES, instance=user)
        profile_form = UserProfileForm(request.POST, request.FILES, instance=profile)
        if user_form.is_valid() and profile_form.is_valid():
            user_form.save()
            profile_form.save()
            return redirect('NewApp:logindex')
    else:
        user_form = UserUpdateForm(instance=user)
        profile_form = UserProfileForm(instance=profile) 
    return render(
        request,
        'NewApp/userprofile_form.html',
        {'user_form': user_form, 'profile_form': profile_form,}
    )
