Validate JSON

Hi

I have this json:

data = {
    "company": "Google",
    "members": [
        {
            "type": 2,
            "name": "James",
            "age": 25
        },
        {
            "type": 1,
            "name": "Maria",
            "age": 22
        },
        {
            "type": 2,
            "name": "George",
            "age": 44
        }
    ]
}

I just don’t know how to validate the members age, because the number of members is not fixed, it could be 1, 2 or more and it needs to be validated by the type field.

For example: George’s age must return an error because his type (2) needs to be between 18 and 30

Validating a relationship between two fields can also be accomplished using schema level validation. With schema validation, you end up writing the polymorphism discriminator in the validator and writing the validation procedurally. If you have more than one field that needs to customize validation based on the type, it is more practical to use a library like marshmallow-polyfield to avoid duplicating the discriminator and allow using the declarative validators marshmallow provides.

I managed to make using Marshmallow Schema. Thank you
