在同一表格上更新用户和用户个人资料 [英] update user and user profile on same form

问题描述

我为一些其他用户信息创建了userProfile。这是我的模型：

i created userProfile for some additional user information. here my model:

class UserProfile(models.Model):
    user = models.OneToOneField(User)
    picture = models.ImageField(upload_to=get_upload_path, blank=True)

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

def create_user_profile(sender, **kwargs):
    u = kwargs["instance"]
    if not UserProfile.objects.filter(user=u):
        UserProfile(user=u).save()

post_save.connect(create_user_profile, sender=User)

我需要设置页面，在此页面中，我将同时更新用户和用户配置文件字段的某些字段。这是我的表单：

I need settings page and in this page i will update some fields of user and user profile fields at the same time. Here my forms:

class UpdateUserForm(ModelForm):
    class Meta:
        model = User
        fields = ['first_name', 'last_name']

class UpdateUserProfileForm(ModelForm):
    class Meta:
        model = UserProfile
        exclude = ['user']

我的模板中有一个表单，相关功能为：

i have one form in my template and related function is:

def post(self, request, *args, **kwargs):
    update_user_form = UpdateUserForm(data=request.POST, instance=request.user)
    update_user_profile_form = UpdateUserProfileForm(data=request.POST)
    if update_user_form.is_valid() and update_user_profile_form.is_valid():
        user = update_user_form.save()
        userProfile = update_user_profile_form.save(commit=False)
        userProfile.user = user
        userProfile.save()

在这种情况下，我收到列user_id不是唯一的错误。为什么要尝试为此用户添加新的用户个人资料？

in this case i am getting "column user_id is not unique" error. why this is trying to add new user profile with this user?

这种情况下的最佳做法是什么？

what is best practice for this case?

谢谢

推荐答案

我前一段时间也遇到了同样的问题。最后，我选择更改自定义用户模型以使其继承自AbstractUser（有关更多信息，请参见： https://docs.djangoproject.com/en/dev/topics/auth/customizing/ ），而不是将其链接到具有onetoonefield的用户：

I had the same problem a while ago. In the end I opted to change my custom user model to make it inherit from AbstractUser (more info on this here: https://docs.djangoproject.com/en/dev/topics/auth/customizing/) instead of linking it to User with a onetoonefield:

models.py：

models.py:

class CustomUser(AbstractUser):
    picture = models.ImageField(upload_to=get_upload_path, blank=True)

views.py：

class UpdateUser(LoginRequiredMixin, UpdateView):
    model = CustomUser
    fields = ('first_name', 'last_name', 'picture')
    template_name = 'user/edit.html'
    success_url = reverse_lazy('forum:top')
