Description:
readycheck 1.0.1
readycheck
Python package providing utilities to check classes attributes when accessing it.
Installation
Use the package manager pip to install readycheck:
pip install readycheck
Dependencies
Python ≥ 3.5
Goal
The goal of this module is to allow to add custom checks when accessing class
attributes.
It is designed to build classes that store objects not available at import time
(e.g. later fetched from a distant service). It avoid us the pain to check if
the connection has been established each time we need these objects: trying to
access them will automagically raise an exception if they are not ready.
Usage
This package's main external API in the ReadyCheck class.
This class is not meant to be instantiated (see documentation for details),
but to be subclassed using a custom check function:
from readycheck import ReadyCheck
class User(ReadyCheck, check_type=dict, check=lambda val: "name" in val):
john = {"id": "<john_id>", "area": 2}
jane = {"id": "<jane_id>", "area": 5}
Usage:
>>> User.john
Traceback (most recent call last):
...
readycheck.NotReadyError: 'john' is not ready yet!
>>> john_data = User.get_raw("john")
>>> User.john = some_lib.load_user(john_data)
>>> User.john
{'id': '<john id>', 'area': 2, 'name': 'John Doe', 'subscribed': False}
