在创建模型时获取 _wrapped_view() 至少需要 1 个参数（给定 0）

Question

我有一个注册表单，提交后我收到以下错误。

_wrapped_view() 至少需要 1 个参数（给定 0）

当我在我的 view.py 中实例化一个新的 UserProfile 对象时会发生这种情况，即 AppUserRegistration 函数。

我正用头撞墙。那里的错误消息根本没有多大帮助。

models.py

class UserProfile(models.Model):
    user = models.OneToOneField(User)
    birthday = models.DateField(null=True, blank=True)
    profession = models.CharField(max_length=100, null=True, blank=True)
    created = models.DateTimeField()
    modified = models.DateTimeField()

views.py

from django.http import HttpResponseRedirect
from django.contrib.auth.models import User
from django.contrib.auth.decorators import login_required
from django.shortcuts import render_to_response
from django.template import RequestContext
from AutoDIY.forms import RegistrationForm, LoginForm, UserProfileAboutForm
from AutoDIY.models import UserProfile
from django.contrib.auth import authenticate, login, logout 

def AppUserRegistration(request):
    if request.user.is_authenticated():
        return HttpResponseRedirect('/')
    if request.method == 'POST':
        form = RegistrationForm(request.POST)
        if form.is_valid():
            first_name = form.cleaned_data.get('first_name')
            last_name = form.cleaned_data.get('last_name')
            username = form.cleaned_data.get('username')
            email = form.cleaned_data.get('email')
            password = form.cleaned_data.get('password')
            user = User.objects.create_user(username=username,
                                            email=email,
                                            password=password)
            user.first_name = first_name
            user.last_name = last_name
            user.save()
            user_profile = UserProfile(user=user) # fails right here
            ...

Answer 1

从您发布的错误来看，实际上 UserProfile 不是模型类，而是一些函数（可能已装饰）。检查您的代码库并确保您没有定义名为 UserProfile 的函数。也许您在 views.py 的下面某处有名为 UserProfile 的视图函数？

Answer 2

if form.is_valid():
    first_name = form.cleaned_data['first_name']
    last_name = form.cleaned_data['last_name']
    username = form.cleaned_data['username']
    email = form.cleaned_data['email']
    password = form.cleaned_data['password']

    reg = User.objects.create_user(
        username=username,
        password=password, 
        email=email
        ) 

    reg.is_active = True
    reg.first_name = first_name
    reg.last_name = last_name
    new_user = reg.save()

    // This will give the system seconds (time) to generate new id 
    // before giving to userprofile
    messages.info(request, "User successfully registered. Creating profile...")

    UserProfile.objects.create(user_id=new_user.id, other_field='')
