添加用户 django 后禁用注销

Question

我需要在 django 中创建管理面板，管理员将能够添加“从用户扩展”的学生，我终于可以添加它们，但之后我得到“'AnonymousUser' 对象没有属性 '_meta' 用户已正确添加到数据库中，但 django 让我退出了！ 我怎样才能保持我当前的用户会话！

 class student(models.Model):

    Computers = 1
    Communications = 2
    Dep_CHOICES = (
        (Computers, 'Computers'),
        (Communications, 'Communications'),
    )

    user = models.OneToOneField(User, on_delete=models.CASCADE)
    dep = models.PositiveSmallIntegerField(choices=Dep_CHOICES, null=True, blank=True)
    deg = models.FloatField(null=True, blank=True)

    def __str__(self):  # __unicode__ for Python 2
        return self.user.username


def create_user_profile(sender, instance, created):
    if created:
        student.objects.create(user=instance)


def save_user_profile(sender, instance , **kwargs):
    instance.student.save()



class UserForm(ModelForm):
    class Meta:
        model = User
        fields = ('username', 'email', 'password')


class studentForm(ModelForm):
    class Meta:
        model = student
        fields = ('dep', 'deg')

def add_stu(request):
    if request.method == 'GET':
        return render(request, "add_student.html")
    else:
        user_form = UserForm(request.POST, instance=request.user)
        profile_form = studentForm(request.POST, instance=request.user.student)

        user_form.save()
        profile_form.save()

Answer 1

您不能直接保存 profile_form，因为它与用户有外键关系并且是必需的。因此，在您保存 profile_form 之前，您需要先保存用户，然后将用户添加到配置文件中。

def add_stu(request):
    if request.method == 'GET':
        return render(request, "add_student.html")
    else:
        user_form = UserForm(request.POST)
        profile_form = studentForm(request.POST)
        new_user = user_form.save()
        profile = profile_form.save(commit=False)
        profile.user = new_user
        profile.save()
