python manage.py startapp myapp

from django.db import models

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

    def __str__(self):
        return self.name

class Product(models.Model):
    name = models.CharField(max_length=100)
    category = models.ForeignKey(Category, on_delete=models.CASCADE)

    def __str__(self):
        return self.name

from django.contrib import admin
from .models import Category, Product

class ProductInline(admin.TabularInline):
    model = Product

@admin.register(Category)
class CategoryAdmin(admin.ModelAdmin):
    inlines = [ProductInline]

@admin.register(Product)
class ProductAdmin(admin.ModelAdmin):
    list_display = ('name', 'category')

python manage.py runserver
