django how to authenticate user until verify email - django

Question

How to authenticate user until he verify the email?
In my sign up process, I create the User, which means he can login even without verify email. Is there a build-in method to set a un-verified status on a User?

Answer 1

models.py
email_active = models.BooleanField(default=False,
verbose_name=u'Email active ')
views.py
username = request.POST.get("username")
password = request.POST.get("password")
user = authenticate(username=username, password=password)
if user is not None:
if user.email_active:
login(self.request, user)
return HttpResponse("login success")
else:
return HttpResponse("user email is not active")
else:
return HttpResponse("username or password error")
you can active email by send email with verify_code,user can use verify_code to active their email.
Demo:
models.py:
class EmailVerify(models.Model):
owner = models.ForeignKey(User,
on_delete=models.CASCADE,
verbose_name='owner')
verify_code = models.CharField(max_length=254,
null=True,
verbose_name='verify_code ')
def update(self):
self.verify_code = self.generate_key()
self.save()
return self.verify_code
def get_active_email_url(self, request):
from django.urls import reverse
url = '{}?active_code={}'.format(request.build_absolute_uri(reverse('user_login', args=())), self.verify_code)
return url
#staticmethod
def generate_key():
return binascii.hexlify(os.urandom(20)).decode()

verbose_name = 'EmailVerify'

verify = EmailVerify.objects.filter(owner=user).first()
else:
verify = EmailVerify.objects.create(owner=user)
verify.update()
title = u"{} active email".format(site_name)
message = "".join([
u"click this link can active your email:\n\n",
"{}\n\n".format(verify.get_active_email_url(request=request)),
])
try:
send_mail(title, message, settings.DEFAULT_FROM_EMAIL, [user.email])
