I'm trying to modify Django's built-in authetnication system by adding a custom user model. The customized model is defined inside an app named accounts:
from django.db import models
from django.contrib.auth.models import AbstractUser
from django.conf import settings
# Create your models here.
COUNTRIES = settings.COUNTRY_CHOICES
class CustomUser(AbstractUser):
zip_code = models.PositiveSmallIntegerField(blank=True, null=True)
city = models.CharField(blank=True, null=True, max_length=64)
address_street = models.CharField(blank=True, null=True, max_length=64)
address_number = models.CharField(blank=True, null=True, max_length=32)
country = models.CharField(blank=True, null=True, choices=COUNTRIES, max_length=8)
I updated the settings.py file this way:
AUTH_USER_MODEL = accounts.CustomUser
I added accounts as an installed app:
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'accounts',
'store',
'cart',
]
When I try to run the python manage.py makemigrations command in terminal to apply changes made to the user model Django's throwing this error:

AUTH_USER_MODEL = accounts.CustomUser
NameError: name 'accounts' is not defined
The error is not only confined to the accounts app, no matter inside which app I try to define the CustomUser model I'm still getting it.
If anyone knows what's causing the problem please help me to resolve it.
The AUTH_USER_MODEL setting [Django-doc] should be a string, not a (qualified) name, so:
# settings.py
# …
# string literal 🖟 🖟
AUTH_USER_MODEL = 'accounts.CustomUser'
As Willem mentioned, you need to update your AUTH_USER_MODEL setting inside settings.py to accounts.CustomerUser model. In addition, you will have to update your schema manually as when you first run migrations, Django will use the default auth.User for multiple foreign keys etc. See the docs here for changing a user mid project.

I've been trying to fix this Django issue. I've just started this project and I'm fairly new to this language so I don't know where exactly is the issue.

Any help I would really appreciate it.
In settings.py, the Installed apps should be written as 'app_name.apps.appconfig'.
The 'appconfig' is the same as the class name in app/apps.py
In you case it might be something like learning_logs.apps.LearningLogsConfig

There is an error in your code for the Product models.
I have corrected it.
from django.db import models
class Product(models.Model):
title = models.CharField(max_length=120) # max_length = required
description = models.TextField(blank=True, null=True)
price = models.DecimalField(decimal_places=2, max_digits=10000)
summary = models.TextField()
featured = models.BooleanField() #only new added line
the default value for a boolean field is always false.

I'm confused what's wrong with my code...
dynamic_scraper section in INSTALLED_APPS should go without .models. e.g.
INSTALLED_APPS = [

'dynamic_scraper',
]
Also, since you're using 1.10, it worth to add an AppConfig for your application: docs
I'm currently trying to build a blog using Django. I've been facing this error for a few hours now. I'm not quite sure if this has anything to do with the directories but the error occurs when I try to register my model in the admin.py file.
from django.contrib import admin
from .models import Post
# Register models
admin.site.register(Post)
The directories look as follows:
blog
models
Post
Category
admin.py
settings
static
templates

Whenever I comment the register line everything works fine.
Instead of writing "from .models import Post" you should write "from .models.Post import Post".
First "Post" is a modulename (file name), second one is a class name.

This means that line #80 of your settings.py file uses a name (base - obviously expected to be a function) that is not defined. Your settings file is missing either an import or a function definition. What base is supposed to do etc is beyond our knowledge (it's definitly not a builtin, and nothing standard in a django settings file) but you should now since it's your project.
