Registering Models in the Admin Panel

To make your models available in the Django Admin interface, you need to register them in the admin.py file of your app.

1. Basic Model Registration: Example: Registering the Book model.

   from django.contrib import admin
   from .models import Book
   
   admin.site.register(Book)
   

   After registration, the Book model will be available in the admin interface.

2. Customizing Model Registration: To customize the admin interface for a model, you need to create a custom admin class. Example:

   from django.contrib import admin
   from .models import Book
   
   class BookAdmin(admin.ModelAdmin):
       list_display = ('title', 'author', 'published_date')
       search_fields = ('title', 'author')
   
   admin.site.register(Book, BookAdmin)
