Step 1: Create the serializers.py file in app folder.

Step 2: Create a serializer.

In DRF, when you create a serializer for a model, you use the Meta class to provide additional information on how the serializer should work.

from rest_framework import serializers
from .models import Product


class ProductSerializer(serializers.ModelSerializer):
    class Meta:
        model = Product
        fields = '__all__'

• model = Product: This line tells the serializer to use the Product model for serialization. It means the serializer will work with objects of type Product.

• fields = '__all__': This instructs the serializer to include all fields of the Product model in the serialization. If you wanted to specify particular fields, you could list them in an array instead of using '__all__' (like the example below).

fields = ['name', 'description', 'price']

The entire Meta class defines which model to use and which fields of that model to include in the serialization. This allows the Django REST framework to automatically generate a serializer for the model with minimal effort on your part.
