Django admin application

• Allows creating, viewing, updating, and deleting records using models.
• Simplifies testing models and data during development.
• Useful for managing data in production environments.
• Recommended only for internal data management.
• Dependencies needed: Django Admin Documentation.
• Register models to add them to the admin interface.
• Configure the admin area for better display.
• Create a new "superuser."

Registering models

Register models in /django-locallibrary-tutorial/catalog/admin.py. This is the simplest way of registering models with the site.

Creating a superuser

A superuser account has full access to the site and all needed permissions using manage.py.

• Log into the admin site with a user account that has Staff status enabled.
• View and create records with permissions to manage all objects.

In the same directory as manage.py run:

python3 manage.py createsuperuser

Restart the development server to test the login:

python3 manage.py runserver

Logging in and using the site

Open the /admin URL and enter the superuser credentials. The GUI allows you to view models and edit field values.

Advanced configuration

List views and detail views provide greater customization

Find a reference of the admin site in the docs: https://docs.djangoproject.com/en/5.0/ref/contrib/admin/

Register a ModelAdmin class

Comment out the original registrations. Then Define a ModelAdmin class and register it with the model. See: https://docs.djangoproject.com/en/5.0/ref/contrib/admin/#modeladmin-objects

Configure list views

Use list_display to add additional fields to the view. See more at https://docs.djangoproject.com/en/5.0/ref/contrib/admin/#django.contrib.admin.ModelAdmin.list_display

Add list filters

To filter displayed items, list fields in the list_filter attribute.

Sectioning the detail view

To add sections, refer to: https://docs.djangoproject.com/en/5.0/ref/contrib/admin/#django.contrib.admin.ModelAdmin.fieldsets

Inline editing of associated records

For inline editing of associated records, refer to: https://docs.djangoproject.com/en/5.0/ref/contrib/admin/#django.contrib.admin.ModelAdmin.inlines
