I am trying to create a UserProfile model in my user app and instead of inheriting from models.Model, I am inheriting from django's own User model so that I would have a custom user model wwith extra fields. But when I run the python manage.py test command it gives me the following error:

 Creating test database for alias 'default'...

Here is what my models.py look like.

class UserProfile(User):
 levels = [
 ('Beginner', 'Beginner'),
 ('Elementary', 'Elementary'),
 ('Pre-Intermediate', 'Pre-Intermediate'),
 ('Intermediate', 'Intermediate'),
 ('Upper-Intermediate', 'Upper-Intermediate'),
 ('Advanced', 'Advanced'),
 ]

 courses = [
 ('English', 'English'),
 ('Russian', 'Russian'),
 ('Mathematics', 'Mathematics'),

 ]

 titles = [
 ('Teacher', 'Teacher'),
 ('Student', 'Student'),
 ]

 icons = [
 ('fa-user', 'User'),
 ('fa-user-graduate', 'Student'),
 ('fa-user-ninja', 'Ninja'),
 ('fa-user-tie', 'Tie'),
 ('fa-user-md', 'Doctor'),
 ('fa-user-astronaut', 'Astronaut'),
 ('fa-user-secret', 'Spy'),
 ('fa-user-injured', 'Injured'),
 ]

 bio = models.TextField(blank=True)
 country = models.CharField(max_length = 100)
 course = models.CharField(
 max_length = 20,
 choices=courses,
 default='English',
 )
 level = models.CharField(
 max_length = 20,
 choices=levels,
 default='Beginner',
 )
 title = models.CharField(
 max_length = 20,
 choices=titles,
 default='Student',
 )
 avatar = models.ImageField(default='avatars/default_avatar.jpg', upload_to='avatars')
 icon = models.CharField(
 max_length = 150,
 choices = icons,
 default = 'fa-user'
 )


 def is_student(self):
 return self.title == 'Student'


 def is_teacher(self):
 return self.title == 'Teacher'

 def get_absolute_url(self):
 return reverse('user-profile', kwargs='slug': self.username)

 def __str__(self):
 return f'self.username Profile'

 def save(self, **kwargs):
 super().save()

 img = Image.open(self.avatar.path)

 if img.height != img.width:
 w = img.width
 h = img.height

 if h > w:
 a = h - w
 box = (a/2, a/2, w, w)
 else:
 a = w - h
 box = (a/2, a/2, h, h)

 img = img.crop(box)

 if img.height > 500 or img.width > 500:
 output_size = (500, 500)
 img.thumbnail(output_size)
 img.save(self.avatar.path)
 else:
 img.save(self.avatar.path)

And I have added it in settings.py

I found what the problem was about!!!

It was because I was using my UserProfile model from user app as a ForeignKey on another model called Post as an author and the problem was there. Importing the model from another app directly and passing it there gives such error as it turns out. So following the documentation here https://docs.djangoproject.com/en/2.1/ref/models/fields/#django.db.models.ForeignKey

I created another model called User in my another app and inherited from my UserProfile and here is how my jollywood/models.py looks:

 from django.db import models
from django.utils import timezone
from user.models import UserProfile


class Post(models.Model):
 title = models.CharField(max_length = 150)
 auth = models.ForeignKey('User', on_delete=models.CASCADE)
 content_shown = models.TextField()
 content_hidden = models.TextField()
 date = models.DateTimeField(default=timezone.now)
 read = models.PositiveIntegerField()
 liked = models.PositiveIntegerField()
 thumbnail = models.ImageField(default='post_thumbs/default_thumb.jpg', upload_to='post_thumbs')


 def __str__(self):
 return self.title

class User(UserProfile):
 pass

and here is what my user/models.py looks like:

from django.db import models
from django.contrib.auth.models import User
from PIL import Image
from django.urls import reverse


class UserProfile(User):
 levels = [
 ('Beginner', 'Beginner'),
 ('Elementary', 'Elementary'),
 ('Pre-Intermediate', 'Pre-Intermediate'),
 ('Intermediate', 'Intermediate'),
 ('Upper-Intermediate', 'Upper-Intermediate'),
 ('Advanced', 'Advanced'),
 ]

 courses = [
 ('English', 'English'),
 ('Russian', 'Russian'),
 ('Mathematics', 'Mathematics'),

 ]

 titles = [
 ('Teacher', 'Teacher'),
 ('Student', 'Student'),
 ]

 icons = [
 ('fa-user', 'User'),
 ('fa-user-graduate', 'Student'),
 ('fa-user-ninja', 'Ninja'),
 ('fa-user-tie', 'Tie'),
 ('fa-user-md', 'Doctor'),
 ('fa-user-astronaut', 'Astronaut'),
 ('fa-user-secret', 'Spy'),
 ('fa-user-injured', 'Injured'),
 ]

 bio = models.TextField(blank=True)
 country = models.CharField(max_length = 100)

 max_length = 20,

 max_length = 20,
 choices=levels,
 default='Beginner',
 )
 title = models.CharField(
 max_length = 20,
 choices=titles,
 default='Student',
 )
 avatar = models.ImageField(default='avatars/default_avatar.jpg', upload_to='avatars')
 icon = models.CharField(
 max_length = 150,
 choices = icons,
 default = 'fa-user'
 )
 instagram = models.CharField(max_length = 100, null=True)
 facebook = models.CharField(max_length = 100, null=True)
 twitter = models.CharField(max_length = 100, null=True)
 telegram = models.CharField(max_length = 100, null=True)

 def is_teacher(self):
 return self.title == 'Teacher'

 def get_absolute_url(self):
 return reverse('user-profile', kwargs='slug': self.username)

 def __str__(self):
 return f'self.username Profile'

 def save(self, **kwargs):
 super().save()

 img = Image.open(self.avatar.path)

 if img.height != img.width:
 w = img.width
 h = img.height

 if h > w:
 a = h - w
 box = (a/2, a/2, w, w)
 else:
 a = w - h
 box = (a/2, a/2, h, h)

 img = img.crop(box)

 if img.height > 500 or img.width > 500:
 output_size = (500, 500)
 img.thumbnail(output_size)
 img.save(self.avatar.path)
 else:
 img.save(self.avatar.path)
