Description of the bug
After upgrading Django to version 4.2.1, an import error occurs when running the server. The error message states:
File "Multi-Authors-advanced-Django-Blog/src/urls.py", line 4, in <module> from django.conf.urls import url ImportError: cannot import name 'url' from 'django.conf.urls' (/home/username/blog/.env/lib/python3.11/site-packages/django/conf/urls/__init__.py)

To Reproduce
Steps to reproduce the behavior:

1. Upgrade Django to the latest version (django==4.2.1).
2. Run the server.
3. Observe the import error.

Expected behavior
The server should run successfully without any import errors after upgrading Django to version 4.2.1.

solution
In Django 4.0 and above, the url function has been deprecated and replaced with the path function. To resolve the import error, you need to update the code in the Multi-Authors-advanced-Django-Blog/src/urls.py file.

Replace the line from django.conf.urls import url with the following line:

from django.urls import path

since the above line is already imported all you need is to remove this line
from django.conf.urls import url

Make sure to update any URLs defined using the old url function to use path instead. This change is necessary due to the deprecation of the url function in Django 4.0 and above.

Warning description
When running the project, the following warning messages are displayed:

WARNINGS: blog.Blog: (models.W042) Auto-created primary key used when not defining a primary key type, by default 'django.db.models.AutoField'. HINT: Configure the DEFAULT_AUTO_FIELD setting or the BlogConfig.default_auto_field attribute to point to a subclass of AutoField, e.g. 'django.db.models.BigAutoField'. blog.Category: (models.W042) Auto-created primary key used when not defining a primary key type, by default 'django.db.models.AutoField'. HINT: Configure the DEFAULT_AUTO_FIELD setting or the BlogConfig.default_auto_field attribute to point to a subclass of AutoField, e.g. 'django.db.models.BigAutoField'. blog.Comment: (models.W042) Auto-created primary key used when not defining a primary key type, by default 'django.db.models.AutoField'. HINT: Configure the DEFAULT_AUTO_FIELD setting or the BlogConfig.default_auto_field attribute to point to a subclass of AutoField, e.g. 'django.db.models.BigAutoField'. ...

To Reproduce
Steps to reproduce the behavior:

1. Run the project.
2. Observe the warning messages mentioned above.

Expected behavior
The project should not display any warning messages regarding the auto-created primary key.

Solution
To address these warnings, you can add the following line to your settings.py file:

DEFAULT_AUTO_FIELD = 'django.db.models.BigAutoField'

This configuration specifies the default auto field type as BigAutoField, which is a subclass of AutoField. By setting this value, you indicate that you want to use BigAutoField as the primary key type for the affected models (e.g., Blog, Category, Comment, etc.).

Adding this line to your settings.py file should resolve the warnings related to the auto-created primary key.
