Question

我已经为它创建了注册页面和模型，当用户注册时，他会被重定向到主页。当我点击注册用户被插入数据库但是当它重定向到主页时我收到这个错误：

追溯：

这是模型：

class user_model(AbstractBaseUser):
    user_id = models.CharField(max_length=50, primary_key=True)
    username = models.CharField(max_length=50, unique=True)
    first_name = models.CharField(max_length=50, default="None")
    last_name = models.CharField(max_length=50, default="None")
    email = models.EmailField(default="None")
    password = models.CharField(max_length=150, default="abc123")

    '''Custom user information fields. '''
    myself = models.CharField(max_length=300, default="None")
    address = models.CharField(max_length=300, default="None")
    mobilePh = models.CharField(max_length=20, default="None")
    workPh = models.CharField(max_length=20, default="None")
    workEmail = models.EmailField(default="None")
    last_login = models.CharField(max_length=50, default="None")
    profile_pic = models.ImageField(width_field=None, height_field=None,
                                    blank=True, default="None",
                                    upload_to=upload_profile_pic)
    banner_pic = models.ImageField(width_field=None, height_field=None,
                                   blank=True, default="None",
                                   upload_to=upload_banner_pic)

    USERNAME_FIELD = 'username'
    REQUIRED_FIELDS = ['user_id']

    class Meta:
        db_table = 'user_model'
        app_label = 'welcome'

这是注册视图

def register(request):
    if request.method == 'POST':
    if validate_registration_attributes(request.POST):
        user_uuid = uuid.uuid4()
        try:
        user = User.objects.create(user_id=str(user_uuid),                                                                     last_login=str(datetime.datetime.now()),
                       username=request.POST['username'],
                       first_name=request.POST['first_name'],
                       last_name=request.POST['last_name'],
                       email=request.POST['email'],
                       profile_pic="blank_image.png",
                       banner_pic="blank_image.png",
                       password='',
                       )
        user.set_password(request.POST['passwd_1'])
        user.save()

        login(request, user)
        return HttpResponseRedirect('/home')
        except Exception as err:
        user.delete()
        print "Something happened"
        raise Exception("""EXCEPTION at register-user.objects.create in
                        userObject:%s""" % (err))
        global exceptmsg
        return HttpResponseRedirect('/welcome')
    else:
        print "New account registration form validation failed"
        context = {'RegisterResponse': exceptmsg}
        return render(request, 'welcome.html', context)

这是主页视图：

def home(request):
    if request.user.is_authenticated():
    return HttpResponseRedirect('/home')
    else:
    return HttpResponseRedirect('/welcome')

是模型问题还是其他问题。请帮忙。

我忘记覆盖 settings.py 中的默认用户模型。我将 AUTH_USER_MODEL 的值更改为 myappname.user_model。现在它工作正常。
