DbClass module for automatic serialization and deserialization

DbClass module is ment to be used in conjunction with databases or json which require serialization to save data to and deserialization to get data from.

Installation

You can install the db_class package using pip:

pip install db_class

Example

Here's an example of how to use the simulate_game function:

import json
import sys
from dataclasses import dataclass
from datetime import datetime
from decimal import Decimal

from src import DbClass
from src import DbClassLiteral


def test_serialize_literal():
    @dataclass
    class Bar(DbClassLiteral):
        dictionary: dict
        date: datetime
        decimal: Decimal

    @dataclass
    class Foo(DbClass):
        dictionary: dict
        date: datetime
        decimal: Decimal
        bar: Bar

    foo = Foo({}, datetime.now(), Decimal(1), Bar({}, datetime.now(), Decimal(1)))
    serialized = foo.get_db_representation()
    try:
        json.dump(serialized, sys.stdout)
    except:
        assert False
    deserialized = Foo.from_dict(serialized)
    assert deserialized == foo


def test_serialize():
    @dataclass
    class Bar(DbClass):
        dictionary: dict
        date: datetime
        decimal: Decimal

    @dataclass
    class Foo(DbClass):
        dictionary: dict
        date: datetime
        decimal: Decimal
        bar: Bar

    foo = Foo({}, datetime.now(), Decimal(1), Bar({}, datetime.now(), Decimal(1)))
    serialized = foo.get_db_representation()
    foo.bar = foo.bar._id
    try:
        json.dump(serialized, sys.stdout)
    except:
        assert False
    deserialized = Foo.from_dict(serialized)
    assert deserialized == foo
