Adding data to created sqlite database in Django

I have created two classes in models.py in my application.

models.py

 from django.db import models

 # Create your models here.
 class User(models.Model):
 first_name = models.CharField(max_length=264, unique=True)
 last_name = models.CharField(max_length=264, unique=True)
 email = models.CharField(max_length=264,unique=True)

 def __str__(self):
    return self.first_name

 class NewUser(models.Model):
 categorie = models.ForeignKey('User',on_delete=models.DO_NOTHING)
 area = models.CharField(max_length=264)

def __str__(self):
    return self.name

enter image description here

Most likely you haven't migrated properly. Try:

python manage.py makemigrations
python manage.py migrate

The models show up in the admin because they are present in the apps models.py. This is not related to the database!

Since you don't have any custom fields in your User model, you dont need to create a seperate User class, only you have to import the built in User class.

from django.contrib.auth.models import User

class NewUser(models.Model):
   categorie = models.ForeignKey('User',on_delete=models.DO_NOTHING)
   area = models.CharField(max_length=264)

   def __str__(self):
      return self.categorie.user.username

You can still get username, first_name, last_name, email etc from the default user class. Refer: https://docs.djangoproject.com/en/3.0/ref/contrib/auth/#django.contrib.auth.models.User
