Custom Validators

Build your own validation logic on top of the validate function.

Extend the built-in validate() with custom rules.

from gdtest_sec_index_hero import validate

def validate_positive(record):
    base_ok = validate({'value': int}, record)
    return base_ok and record['value'] > 0

assert validate_positive({'value': 42})
assert not validate_positive({'value': -1})
