when i try to login and sed password and email id.It gets both field data but authenticate method return None. For this i write AUTH_USER_MODEL = 'register.Consultants' in my setting file, then another error showing AttributeError: type object 'Consultants' has no attribute 'REQUIRED_FIELDS'
How can i get logged in by authenticate method.Why it is not working Please help me in this
you have your custom user model named MyUser however in your configuration you reference totally different register.Consultants - use MyUser model.
From what can I see, every user will be a Consultant, so why not to simplify all of your code and create one model class Consultants which will handle user and profile information:
class Consultant(AbstractBaseUser):
email = models.EmailField(
verbose_name='email address',
max_length=255,
unique=True,
)
first_name = models.CharField(max_length=255, blank=True, null=True)
last_name = models.CharField(max_length=255, blank=True, null=True)
username = models.CharField(max_length=255, blank=True, null=True)
consul_pic = models.ImageField(upload_to="/homeDocuments/pro//Registration/consul_pic", blank=True, null=True)
mobile_no = models.CharField(max_length=255, blank=True, null=True)
country = models.IntegerField(validators=[MaxLengthValidator(11)], blank=True, null=True)
state = models.IntegerField(validators=[MaxLengthValidator(11)], blank=True, null=True)
city = models.IntegerField(validators=[MaxLengthValidator(11)], blank=True, null=True)
experience = models.IntegerField(default=0, blank=True, null=True)
skills = models.CharField(max_length=255, blank=True, null=True)
education = models.CharField(max_length=255, blank=True, null=True)
linkedin_id = models.CharField(max_length=255, blank=True, null=True)
created_on = models.DateTimeField(auto_now_add=True, blank=True, null=True)
last_updated_on = models.DateTimeField(auto_now=True, blank=True, null=True)
last_login = models.DateTimeField(auto_now_add=True, blank=True, null=True)
is_active = models.BooleanField(default=True)
is_admin = models.BooleanField(default=False)
objects = MyUserManager()
USERNAME_FIELD = 'email'
# REQUIRED_FIELDS = ['date_of_birth']
def get_full_name(self):
# The user is identified by their email address
return self.email
def get_short_name(self):
# The user is identified by their email address
return self.email
def __unicode__(self): # __unicode__ on Python 2
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
few, off-topic comments:
user_name = models.OneToOneField(MyUser) should be user = models.OneToOneField(MyUser) , so then it will be clear when you will access consultant_x.user.name auto_now_add and auto_now flags - much better than default 下一篇: 身份验证方法在django中返回无
