I am trying to login using email instead of username in django, but it is not working. I am not getting any error also.
I also looked up solution for solutions in stackoverflow and other blogs/post also but not getting the output.
Can you please review my code where I am wrong/ modification needed. Any suggestions or changes are welcome.
Here is my code:
models.py
from django.db import models
from django.contrib.auth.models import (BaseUserManager,AbstractBaseUser)
# Create your models here.
class UserManager(BaseUserManager):
def create_user(self, email,password=None):
"""
Creates and saves a User with the given email, date of
birth and password.
"""
if not email:
raise ValueError('Users must have an email address')
user = self.model(
email=self.normalize_email(email),
)
user.set_password(password)
user.save(using=self._db)
return user
def create_superuser(self, email, date_of_birth, password):
"""
Creates and saves a superuser with the given email, date of
birth and password.
"""
user = self.create_user(
email,
password=password,
)
user.is_admin = True
user.save(using=self._db)
return user
class MyUser(AbstractBaseUser):
email = models.EmailField(verbose_name='email address',
max_length=255,
unique=True,
)
is_active = models.BooleanField(default=True)
is_admin = models.BooleanField(default=False)
objects = UserManager()
USERNAME_FIELD = 'email'
REQUIRED_FIELDS = []
def __str__(self):
return self.email
def has_perm(self, perm, obj=None):
"Does the user have a specific permission?"
# Simplest possible answer: Yes, always
return True
def has_module_perms(self, app_label):
"Does the user have permissions to view the app `app_label`?"
# Simplest possible answer: Yes, always
return True
@property
def is_staff(self):
"Is the user a member of staff?"
# Simplest possible answer: All admins are staff
return self.is_admin

This line in your login_view
can't be right:
username = form.cleaned_data.get("username")
Your form doesn't have a username
field, it only has an email
field.
