RecursionError: maximum recursion depth exceeded while calling a Python object

[Nagaraj4896]

I am getting RecursionError: maximum recursion depth exceeded while calling a Python object error for following code, Is there any other way to selecting the schema based on a value

import marshmallow
from marshmallow import fields, post_load

class FoodSchema(marshmallow.Schema):
    food_type = fields.String()

    @post_load
    def make_food(self, data, **kwargs):
        food_type = data.get('food_type', '').lower()
        if food_type == 'fruit':
            return FruitSchema().load(data)
        elif food_type == 'vegetable':
            return VegetableSchema().load(data)
        elif food_type == 'meat':
            return MeatSchema().load(data)
        else:
            raise ValueError("Invalid food type")

class FruitSchema(FoodSchema):
    # Add fields specific to the Fruit class here

class VegetableSchema(FoodSchema):
    # Add fields specific to the Vegetable class here

class MeatSchema(FoodSchema):
    # Add fields specific to the Meat class here

print(FoodSchema().load({'food_type':'fruit'}))

You may want to have a look at marshmallow-onfofschema, although I'm not sure it works at schema top-level. It might be limited to polymorphic fields.
