Пакет python3-module-shiftschema: Информация

Filtering and validation library for Python3. Can filter and validate
data in model objects and simple dictionaries with flexible schemas.

Main idea: decouple filtering and validation rules from web forms into
flexible schemas, then reuse those schemas in forms as well as apis and
cli. Model validation and filtering rules should be part of the model
and your domain logic, not your views or forms logic.
