Displaying inline relational fields in admin

When we have a foreign key relation between tables, we can display related fields by making some changes to the admin.py file inside our app. We'll continue working with the model structure laid out in Creating a foreign key link in Django

# admin.py

from django.contrib import admin
from .models import Book, Review


class ReviewInline(admin.TabularInline):
	model = Review
	
	
class BookAdmin(admin.ModelAdmin):
	inlines = [
		ReviewInline,
	]
	list_display = ("title", "author", "price",)
	

admin.site.register(Book, BookAdmin)

We create a TabularInline class for our Review model, and then tell the BookAdmin class to display ReviewInline.
