tinydb-serialization 1.0.0

Serialization for objects that TinyDB otherwise couldn't handle

tinydb-serialization provides serialization for objects that TinyDB otherwise couldn’t handle.

Usage

Creating a Serializer

In this example we implement a serializer for datetime objects:

from datetime import datetime
from tinydb_serialization import Serializer

class DateTimeSerializer(Serializer):
    OBJ_CLASS = datetime  # The class this serializer handles

    def encode(self, obj):
        return obj.strftime('%Y-%m-%dT%H:%M:%S')

    def decode(self, s):
        return datetime.strptime(s, '%Y-%m-%dT%H:%M:%S')

Using a Serializer

You can use your serializer like this:

>>> from tinydb.storages import JSONStorage
>>> from tinydb_serialization import SerializationMiddleware
>>>
>>> serialization = SerializationMiddleware()
>>> serialization.register_serializer(DateTimeSerializer(), 'TinyDate')
>>>
>>> db = TinyDB('db.json', storage=serialization)
>>> db.insert({'date': datetime(2000, 1, 1, 12, 0, 0)})
>>> db.all()
[{'date': datetime.datetime(2000, 1, 1, 12, 0)}]
