How to register a model twice in the Django admin?

Note: If you want to read the blog series on Django Admin customization, then click here.

Suppose you have a Book model as given below.

# app_name/models.py

class Book(models.Model):
    ...
    title = models.CharField(max_length=150)
    is_active = models.BooleanField(default=True)

You might have tried registering a model twice by writing the same code twice, but it gave an error, there is a workaround to register a model twice, you just have to create a proxy model of the same model that you want to register, in this example we are going to create a proxy model of Book and then re-registered it.

# app_name/admin.py

from django.contrib import admin
from django.db import models
from app_name.models import Book

class BookProxy(Book):
    class Meta:
        proxy = True

@admin.register(Book) # First registration of a Book model in Django admin
class BookAdmin(admin.ModelAdmin):
    verbose_name = "Books"

@admin.register(BookProxy) # Second registration of a Book model in Django admin
class BookProxyAdmin(admin.ModelAdmin):
    verbose_name = "New Books"
