✅

You have catelogue_products in the fields, it is by default required. But you are not posting any catelogue_products. You need to post data based on the fields of the serializer. validated data will not contain any other data, but valid data that was set in serializer.

To make it optional you may try to add required=False in the serialzier like this:

class CatalogSerializer(serializers.ModelSerializer):
    catalog_products = CatalogProductsSerializer(source = 'catalogproducts_set',many=True, required=False)
    
    
    class Meta:
        model = Catalog
        fields = ['created_by','client','catalog_products','created_datetime','is_active']
