How can I use multiple foreign keys in Django admin?

You can use multiple foreign keys in Django admin by defining them in your models and then customizing the admin interface.

Can you show me an example of a model with multiple foreign keys?

Sure! Here's a simple example:

class Author(models.Model):
    name = models.CharField(max_length=100)

class Book(models.Model):
    title = models.CharField(max_length=100)
    author = models.ForeignKey(Author, on_delete=models.CASCADE)
    publisher = models.ForeignKey(Publisher, on_delete=models.CASCADE)

In this example, the Book model has two foreign keys: one to Author and another to Publisher.

How do I customize the admin interface for these models?

You can customize the admin interface by creating an admin class for your models. For example:

from django.contrib import admin

class BookAdmin(admin.ModelAdmin):
    list_display = ('title', 'author', 'publisher')

admin.site.register(Book, BookAdmin)

What if I want to filter books by author in the admin?

You can add filters in the admin by using the list_filter attribute in your BookAdmin class:

class BookAdmin(admin.ModelAdmin):
    list_display = ('title', 'author', 'publisher')
    list_filter = ('author',)
