text: Lean schema-enforcing objects
  Project Description
  Travis:
  CircleCI:
  Base library for defining lean “contract” models for Python.
  Abstract
  This is an implementation of “models” similar to those you see in most ORMs / forms definition systems, but with the main goal of keeping things as simple as possible.
  No metaclasses or descriptors are involved; no hackish code messing up with standard Python objects functionality either.
  The idea is to have a “layered” library, providing the bare bones needed to define your own schemas, along with some nice helpers for common cases.
  Use cases
  - API clients
  - ORMs
  - Forms
  Example model definition
  from contracts.core import Contract, BaseField # Use BaseField to define your field types, eg. StringField and # IntegerField. class MyModel(BaseObject): first_name = StringField() last_name = StringField() age = IntegerField()
  Then, create some library to make use of the schema somehow 😊.
