Question

我正在尝试为django网站制作一个简单的用户注册表单。这是货物

models.py

from django.db import models
from django import forms
from django.conf import settings
from taggit.managers import TaggableManager
from django.contrib.auth.models import BaseUserManager, AbstractBaseUser

class UserManager(BaseUserManager):
    def create_user(self, email, username_input, password=None):
        if not email:
            raise ValueError('Users must have an email address')
        user = self.model(
            email=self.normalize_email(email),
            username=username_input,    
        )
        user.set_password(password)
        user.save(using=self._db)
        return user

    def create_superuser(self, email, username, password):
        user = self.create_user(email,
            password=password,
            username=username,
        )
        user.is_admin = True
        user.save(using=self._db)
        return user

class CustomUser(AbstractBaseUser):
    # Last login, is active, and password are included automatically
    username                        =       models.CharField(max_length=30, blank=False, unique=True, )
    email                           =       models.EmailField(max_length=150, blank=False)
    join_date                       =       models.DateTimeField(auto_now_add=True)

    objects = UserManager()

    USERNAME_FIELD = 'username'
    REQUIRED_FIELDS = ['email']

class UserForm(forms.Form):
    email                       =           forms.EmailField(max_length=150, required=True)
    username                    =           forms.CharField(max_length=30, required=True)
    password1                   =           forms.CharField(label='Password', widget=forms.PasswordInput(), max_length=30, required=True)
    password2                   =           forms.CharField(label='Password confirmation', widget=forms.PasswordInput(), max_length=30, required=True)

views.py

from django.http import HttpResponse
from django.template import RequestContext, loader
from django.shortcuts import render
from myapp.models import *

def signup(request):
    if request.method == 'POST': # If the form has been submitted...
        if not request.POST['password1'] == request.POST['password2']:
            return HttpResponse("HOLY JESUS BATMAN YOUR PASSWORDS DONT MATCH!")
        form = UserForm(request.POST) # A form bound to the POST data
        if form.is_valid(): # All validation rules pass
            password = request.POST['password1']
            username = request.POST['username']
            email = request.POST['email']
            manager = UserManager()
            manager.create_user(
                email,
                username,
                password,
            )
            return HttpResponse('Huzzah! Success!')
    else:
        form = UserForm() # An unbound form
    return render(request, 'signup.html', {
        'form': form,
    })

微量

Environment:


Request Method: POST
Request URL: http://10.0.1.25:8000/signup/

Django Version: 1.5.1

Traceback:

  13.             username=username_input,    

Exception Type: TypeError at /signup/
Exception Value: 'NoneType' object is not callable

所以，我现在已经把头发拉了一段时间，尝试各种各样的东西，看各种各样的教程，我仍然得到同样的错误。我知道很多，但我认为关注的是create_user函数。任何帮助都会受到超级赞赏，因为这最终会让我感到精神错乱。

定义类

时设置管理器

class CustomUser(AbstractBaseUser):
    ...
    objects = UserManager()

然后在您看来，请致电CustomUser.objects.create_user()。

        CustomUser.objects.create_user(
            email,
            username,
            password,
        )

在视图中实例化管理器无效，如下所示。

        manager = UserManager()
        manager.create_user(
            email,
            username,
            password,
        )

有关详细信息，请参阅Django docs on Managers。
