from .models import Product


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

from rest_framework import serializers

from .models import Product


class ProductSerializer(serializers.ModelSerializer):
    class Meta:

        fields = '__all__'
