使用 UserCreationForm Django 从上一页处理过的电子邮件创建用户

Question

我正在尝试创建一个使用电子邮件作为用户名的用户，并且首先筛选该电子邮件，即该电子邮件未注册，然后创建一个用户。我如何传递或设置 forms.py 中的电子邮件，因为它已在上一页中处理过？

Models.py

from django.contrib.auth.models import AbstractBaseUser
from django.db import models

class CUserManager(models.Manager):
    def _create_user(self, email, password, **extra_fields):

        now = timezone.now();

        if not email:
            raise ValueError(_('Email is required'))

        user = self.model(
            email = email,
            date_joined = now, **extra_fields
        )

        user.set_password(password)  
        user.save(using = self._db)

        return account

    def create_user(self, email, password=None, **extra_fields):
        return self._create_user(email, password, **extra_fields)

    def get_by_natural_key(self, email):
        return self.get(email=email)

    def create_superuser(self, email, password, **extra_fields):
        return self._create_user(email, password,**extra_fields)

class CUser(AbstractBaseUser):

    email = models.EmailField(_('email address'), unique=True)
    first_name = models.CharField(_('first name'), max_length=255)
    last_name = models.CharField(_('last name'), max_length=255)
    date_joined = models.DateTimeField(_('date created'), auto_now_add=True)
    is_active = models.BooleanField(default=True)    

    objects = CUserManager()

    USERNAME_FIELD = 'email'
...

Forms.py

from django.contrib.auth.forms import UserCreationForm

class RegistrationForm(UserCreationForm):

    class Meta: 
        model = CUser
        fields = ('first_name', 'last_name', 'password1', 'password2')

在HTML

 <form action=""  method="post" role="form">
    {% csrf_token %}
  {{ form.as_p }}
  <input type="submit" value="Submit" />
</form>

邮件来自上一页保存的会话['email']。

我如何才能将此会话['email']传递给forms.py？

你可以这样试试：

 # Form

 class RegistrationForm(UserCreationForm):

    class Meta: 
        model = CUser
        fields = ('first_name', 'last_name', 'password1', 'password2')

    def save(self, **kwargs):
       email = kwargs.pop('email')
       user = super(RegistrationForm, self).save(commit=False)
       user.set_password(self.cleaned_data['password1'])
       user.email = email
       user.save()
       return user

# View

# your form codes...

if form.is_valid():
    form.save(email=request.session.get('email'))
    # rest of the codes

我在这里做的是，首先我重写了保存方法以从关键字参数中捕获电子邮件值。然后我将电子邮件值传递给 ModelForm 的保存方法。希望对你有帮助！！
