Django Admin

Introduction

Django Admin provides an automatic admin interface for managing models.

Admin Registration

# app/admin.py
from django.contrib import admin
from .models import Author, Book

@admin.register(Author)
class AuthorAdmin(admin.ModelAdmin):
    list_display = ["name", "email", "created_at"]
    search_fields = ["name", "email"]
    list_filter = ["created_at"]
    ordering = ["name"]

@admin.register(Book)
class BookAdmin(admin.ModelAdmin):
    list_display = ["title", "author", "price"]
    list_select_related = ["author"]
    date_hierarchy = "published_date"

Admin Customization

# Inline models
class BookInline(admin.TabularInline):
    model = Book
    extra = 1

class AuthorAdmin(admin.ModelAdmin):
    inlines = [BookInline]

Actions

class BookAdmin(admin.ModelAdmin):
    actions = ["mark_published", "mark_draft"]
    
    @admin.action(description="Mark as published")
    def mark_published(self, request, queryset):
        queryset.update(status="published")

Practice Problems

1. Register models in admin
2. Customize list display
3. Add search and filters
4. Use inlines for related objects
5. Create custom admin actions
