So, the following command is checking whether there is a library exist with the nam of ‘django-extensions’ :
(env) C:\django\myproject>pip_search django-extensions 🐍 https://pypi.org/search/?q=django-extensions 🐍 ┌─────────────────────────────┬──────────┬──────────────┬────────────────────────────────────────────────────────────────────────────────────────────────┐ Package Version Released Description ├─────────────────────────────┼──────────┼──────────────┼────────────────────────────────────────────────────────────────────────────────────────────────┤ 📂 django-extensions 3.2.1 == 09-09-2022 Extensions for Django 📂 extensions 0.4 17-05-2010 Simple plugin system 📂 django-extensions-shell 1.7.4.1 16-09-2016 Isolated shell_plus command from django-extensions 📂 django-rest-extensions 0.2.0 17-07-2022 create normal api for all your models 📂 django-lookup-extensions 0.2.1 09-08-2018 Django lookup extensions use NOT query. 📂 django-orm-extensions 3.0b3 14-05-2012 Advanced improvement of django-orm with a lot of third-party plugins for use different parts of databases are not covered by the standard orm.As in the above output exist, there is a library with the name of ‘django-extensions’.

After ensuring that the ‘django-extensions’ exist, just install it as follows :
(env) C:\django\myproject\myapp>python -m pip install django-extensions Collecting django-extensions Using cached django_extensions-3.2.1-py3-none-any.whl (229 kB) Requirement already satisfied: Django>=3.2 in c:\django\env\lib\site-packages (from django-extensions) (4.1.2) Requirement already satisfied: asgiref<4,>=3.5.2 in c:\django\env\lib\site-packages (from Django>=3.2->django-extensions) (3.5.2) Requirement already satisfied: tzdata in c:\django\env\lib\site-packages (from Django>=3.2->django-extensions) (2022.5) Requirement already satisfied: sqlparse>=0.2.2 in c:\django\env\lib\site-packages (from Django>=3.2->django-extensions) (0.4.3) Installing collected packages: django-extensions Successfully installed django-extensions-3.2.1 (env) C:\django\myproject\myapp>
-
Soon after successfully install ‘django-extensions’ library, just register it in the Django project’s configuration. It exist in a file with the name of ‘settings.py’ inside the Django project’s folder. Add the ‘django-extensions’ library as follows :
INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'django_extensions', ]
