我想用一些基本信息(姓名，公司...)和电子邮件注册用户。用户提交表单后，我想发送一封电子邮件，其中包含一个链接，该链接将用户带到设置其密码的页面。

我已经尝试了这个问题的解决方案： Django AllAuth - 如何手动发送重置密码电子邮件？电子邮件已发送，电子邮件中的链接正常工作，但我在我的网站上收到断言错误。错误出在setup_user_email(request, user, addresses)函数内部的/allauth/account/utils.py中。行：assert not EmailAddress.objects.filter(user=user).exists()

我在这里做错了什么？

我 models.py：

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

from allauth.account.views import PasswordResetView
from django.conf import settings
from django.dispatch import receiver
from django.http import HttpRequest
from django.middleware.csrf import get_token

class Kompanija(models.Model):
naziv = models.CharField(max_length=50)
adresa = models.CharField(max_length=50, blank=True)
def __str__(self):
return self.naziv
class Meta:
verbose_name = "Kompanija"
verbose_name_plural = "Kompanije"
class CustomUser(AbstractUser):
ime = models.CharField(max_length=30, default='')
prezime = models.CharField(max_length=30, default='')
kompanija = models.ForeignKey(Kompanija, on_delete=models.CASCADE, null=True, blank=True)
is_premium = models.BooleanField('premium status', default=False)
def __str__(self):
return self.ime + " " + self.prezime
@receiver(models.signals.post_save, sender=settings.AUTH_USER_MODEL)
def send_reset_password_email(sender, instance, created, **kwargs):
if created:
request = HttpRequest()
request.method = 'POST'
if settings.DEBUG:
request.META['HTTP_HOST'] = 'www.zahtjevi.com'
else:
request.META['HTTP_HOST'] = 'www.zahtjevi.com'
request.POST = {
'email': instance.email,
'csrfmiddlewaretoken': get_token(HttpRequest())
}
PasswordResetView.as_view()(request)

我 adapter.py：

from allauth.account.adapter import DefaultAccountAdapter
from .models import Kompanija
class UserAccountAdapter(DefaultAccountAdapter):
def save_user(self, request, user, form, commit=True):
user = super(UserAccountAdapter, self).save_user(request, user, form, commit=False)
user.ime = form.cleaned_data.get('ime')
user.prezime = form.cleaned_data.get('prezime')
user.kompanija = Kompanija.objects.get(id=form.cleaned_data.get('kompanija'))
user.is_active = True
user.save()

我 forms.py：

from django import forms
from django.contrib.auth.forms import UserCreationForm, UserChangeForm
from allauth.account.forms import SignupForm
from .models import CustomUser, Kompanija
class CustomUserCreationForm(UserCreationForm):
ime = forms.CharField(max_length=30, label='Ime')
prezime = forms.CharField(max_length=30, label='Prezime')
kompanija = forms.CharField(widget=forms.HiddenInput())
class Meta(UserCreationForm):
model = CustomUser
fields = ('username', 'email', 'ime', 'prezime')
class CustomUserChangeForm(UserChangeForm):
ime = forms.CharField(max_length=30, label='Ime')
prezime = forms.CharField(max_length=30, label='Prezime')
kompanija = forms.CharField(widget=forms.HiddenInput())
class Meta:
model = CustomUser
fields = ('username', 'email', 'ime', 'prezime')

class CustomSignupForm(SignupForm):
ime = forms.CharField(max_length=30, label='Ime')
prezime = forms.CharField(max_length=30, label='Prezime')
kompanija = forms.CharField(widget=forms.HiddenInput())
class Meta:
model = CustomUser
def signup(self, request, user):
user.ime = self.cleaned_data['ime']
user.prezime = self.cleaned_data['prezime']
user.kompanija = Kompanija.objects.get(id=self.cleaned_data['kompanija'])
user.is_active = True
user.save()
return user

class CustomUserAdminForm(forms.ModelForm):
class Meta:
model = CustomUser
fields = ('email', 'ime', 'prezime', 'username', 'kompanija', 'is_premium')

当用户提交注册表单时，将引发此错误。在我的forms.py中，我有一个向用户显示的CustomSignupForm。调用的观点来自 django-allauth(我在我的 urls.pypath('accounts/', include('allauth.urls')),

我试图从我的表单中删除save()，但错误仍然存在，如果我删除settings.py内的ACCOUNT_ADAPTER变量，错误仍然存在......

问题出在 allauthSignupForm的save()方法上：它首先保存用户，然后在最后设置用户的EmailAddress(它有一个单独的用户电子邮件地址模型)。

def save(self, request):
...
adapter.save_user(request, user, self)  # this calls your post-save signal
self.custom_signup(request, user)  # this should call your custom signup method in your custom signup form
setup_user_email(request, user, [])  # this raises the exception
return user

现在，密码重置视图/窗体可确保正确设置用户的EmailAddress(因此它将user.email添加为EmailAddress模型)。由于这是由您的post_save信号完成的，因此它会在调用setup_user_email之前发生。

您应该：

删除post_save信号处理程序，因为它总是会在setup_user_email之前调用。

代码以将重置密码电子邮件发送到表单的save()方法中(首先调用上述super().save()方法，然后发送密码重置电子邮件。

# in your custom form
def save(self, request):
user = super().save(request)
new_request = HttpRequest()
new_request.method = 'POST'
new_request.META['HTTP_HOST'] = 'www.zahtjevi.com'
new_request.POST = {
'email': user.email,
'csrfmiddlewaretoken': get_token(new_request)
}
PasswordResetView.as_view()(new_request)
return user

注意：我感觉您的自定义表单根本没有被使用，您是否按照此处的规定在ACCOUNT_FORMS中定义了它？

注意2(已编辑)：表单的signup()方法是超凡的，它与自定义适配器的save_user()方法执行相同的操作。删除两者之一，可能是窗体的signup()方法，这样您就不会点击 db 两次来保存user对象。

如何在 django-allauth 中使用电子邮件完成用户(设置密码)注册?
