How to run the Django development server

Imagine you are running an e-commerce website like Amazon or Flipkart.

As the store owner, you need a secure backend dashboard where you can:

  • Update product prices

  • Upload product images

  • Manage customer accounts

  • Add new products

  • Remove out-of-stock items

  • Search products

Instead, you use a control panel that allows you to manage everything easily and securely.

Similarly, Django provides a built-in Admin interface that allows developers to manage application data without building a separate management system.

Manually editing the database every time is not convenient.

Introduction to Django Admin

Provides automatic interface for registered models.

Django Admin is a built-in administrative interface.

Used for managing Django models.

Introduction to Django Admin

If Django Admin is already built into Django, how do we activate and start using it in our project?

It enables seamless CRUD operations.

Setting Up Django Admin

Enable Admin App
Add django.contrib.admin in INSTALLED_APPS inside settings.py.

Configure URL

Import admin in urls.py.

Access Admin

Admin becomes accessible after configuration

path('admin/', admin.site.urls)

urlpattern+=[static(settings.MEDIA_URL,
document_root=settings.MEDIA_ROOT)]

Now that the admin interface is available, who is allowed to log in and manage the system?

Creating a Superuser

Required to access the admin panel.

  • Superuser account created.

  • Enables login to admin dashboard.

Steps

After logging in, will our application models automatically appear in the admin panel?

Enter password

Enter email

Enter username

Run command:

python manage.py createsuperuser

Registering Models in Admin

Models must be registered to appear in admin panel.

  • Registered models become visible in admin.

  • CRUD operations become available.

What if our model contains an image field — how does Django Admin handle image uploads?

Steps:

Import admin

Import model

admin.site.register(YourModel)

Use:

Image Upload in Django Admin Panel

1. Define Model with ImageField

upload_to specifies folder inside media directory.

models.CharField(max_length=100)
models.ImageField(upload_to='Images/')
MEDIA_URL = '/media/'
MEDIA_ROOT = BASE_DIR / 'media'

2. Configure Media Settings

Image Upload in Django Admin Panel

4. Upload Process

5. Output

  • Image saved in /media/Images/

  • Path stored in database.

By default, all model fields are displayed in admin. Can we control how the data appears in the list view?

3. Register Model

admin.site.register(Gallery)

Customizing Model Display in Admin

1. Create Custom Admin Class

  • Inherit from admin.ModelAdmin

2. list_display

  • Defines which fields appear in list view.
list_display = ('field1', 'field2', 'field3')

Customizing Model Display in Admin

4. Register with Custom Admin

admin.site.register(YourModel, YourModelAdmin)

3. search_fields

  • Defines searchable fields.

search_fields = ('field1', 'field2')

Control how data is displayed and searched.

Besides customization, what built-in features does Django Admin already provide?

Admin Interface Features

1. Add, Edit, Delete

  • Perform full CRUD operations.

2. Search and Filter

  • Quickly locate specific records.

3. Inline Editing

  • Edit related models from parent model page.

4. Bulk Actions

  • Perform actions on multiple records at once.

If admin allows managing users, how can we update or reset a user's password?

Changing Passwords in Admin

Steps

Reset or update passwords directly from admin panel.

Since admin has full control over application data, how do we keep it secure?

Navigate to Users section.

Select the user.

Click "Change password".

Securing Django Admin

1. Use Strong Passwords

  • Ensure complex and unique admin passwords.

4. Stay Up-to-Date

  • Regularly update Django and dependencies.

3. Limit Access

  • Restrict admin access to authorized IP addresses.

2. Enable HTTPS

  • Encrypt admin traffic.

Summary

4

Admin provides CRUD, search, filtering, inline editing, and bulk actions.

3

Image uploads require ImageField and media configuration.

2

Superuser is necessary for login.
