problems logging in with Django custom backend - python

I have been trying to get my Django custom backend to work and it refuses to accept my credentials, which are correct in the database (I have verified this). It just keeps saying email and password are incorrect.
I am lost and don't know where to go from here with this. I really need help at this point.

incorrect username and password error in web application made in Django

for my web-application which is made in Django and I made a custom users app for users (so I am not using the Django's user). I managed to get the users app working and I created a superuser using this command:
python manage.py createsuperuser
and got this message:
Superuser created successfully.
but when I tried to log in as the superuser in the browser, it did not work and got this error message on the browser (I tried different browsers as well):
Please enter the correct username and password for a staff account. Note that both fields may be case-sensitive.
I paid attention to case-sensitive letters. do you know what the problem could be?
here is the models.py for the users app:

Any help is appreciated.
Getting this error in the browser
According to error, looks like CompanyProfile is not a model class but something else. Is there a chance that you redefine it in views.py? Probably you also define a view with this name?
you don't need to use the form because you can create an account directly to any model like this function
def company_register(request):
if request.method == 'POST':
user = request.POST['user']
image = request.FILES['image']
about = request.POST['about']
location = request.POST['location']
start_date = request.POST['start_date']
website = request.POST['website']
logo = request.FILES['logo']
profile = CompanyProfile.objects.create(user=user, image=image, about=about, location=location, start_date=start_date, website=website, logo=logo)
profile.save()
return Response('Done')
else:
return Response('POST method only accepted')

Dynamic Choices (Those that get updated for new values entered.)

In this project, I got three types of users: ChalkSlateAdmin (this is not a superuser, administrator or staff, etc.), Student and Teacher. All of these can be considered ChalkSlateUser as each have a OneToOne Relationship with the model. ChalkSlateAdmin can be considered an institute and any time someone registers as a ChalkSlateAdmin, there is a new institute as ChalkSlateAdmin has that attribute.
Teachers and Students can join institutes (ChalkSlateAdmin attribute) that are already registered. So, I need to create a form that has choices of institutes that are currently registered.
My question is, how can I define choices that change depending on what institutes (ChalkSlateAdmin attribute) are registered? Before this, I used constant string values for choices like male & female.

For choices option, you can set a method that returns a list with what you want in it.
For instance, for a BankCard model I implemented in one of my projects, I did something similar to what you want to achieve, for the expiration_year. See below :
class BankCard(models.Model):
def _years(year):
return [(year, str(year)) for year in range(year, year + 10)]
expiration_year = models.IntegerField(choices=_years(datetime.datetime.now().year))
Maybe you could do something similar.

Unexpected outcome from model inheritance in Django

I've built a custom user model called "Administrator" for superuser purpose, and the other model called "Customer" for normal user purpose.
I intended to separate them into two different tables, it partly worked but not perfectly. The problem is that when I created an instance for Customer, the instance will be automatically added into the Administrators table, this isn't what I want.
Administrator model on Django admin site
Customer model on Django admin site
Administrator model shown below:
class Administrator(PermissionsMixin, 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)
join_date = models.DateField(auto_now_add=True, editable=False)
objects = AdministratorManager()
USERNAME_FIELD = 'email'
REQUIRED_FIELDS = []
def __str__(self):
return self.email
def get_full_name(self):
return self.email
def get_short_name(self):
return self.get_full_name()
#property
def is_staff(self):
return self.is_admin
def has_perm(self, perm, obj=None):
return True
def has_module_perms(self, app_label):
return True
Customer model shown below:
class Customer(Administrator):
first_name = models.CharField(max_length=255, default='', blank=False)
last_name = models.CharField(max_length=255, default='', blank=False)
DOB = models.DateField()
security_question1 = models.CharField(max_length=500, default='', blank=False)
security_question2 = models.CharField(max_length=500, default='', blank=False)
security_question_answer1 = models.CharField(max_length=500, default='', blank=False)
security_question_answer2 = models.CharField(max_length=500, default='', blank=False)
# REQUIRED_FIELDS = ['email', 'first_name', 'last_name', 'DOB', 'security_question1', 'security_question2']
is_active = True
is_admin = False
You are wrongly inherited the Customer model. It should be inherited from AbstractBaseUser as
class Customer(AbstractBaseUser):
#Your code
UPDATE-1
You can use Abstract class for inheriting.
Define a base class as Abstract and inherit from that class might help you
class BaseClass(PermissionsMixin, 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)
