Welcome to ``dataclasses_sqlitedict`` Documentation
==============================================================================
Sqlite backed dataclasses. It is a light weight persistent storage for dataclasses.
If you are looking for a full featured ORM, please check out SQLAlchemy.


Features
------------------------------------------------------------------------------


Single Row Data Model
------------------------------------------------------------------------------
Each instance of class is a row in the table. And all the instances of the same class share the same database table.

.. code-block:: python

    import dataclasses
    from sqlitedict import SqliteDict
    from dataclasses_sqlitedict import SingleRowDataModel

    @dataclasses.dataclass
    class User(SingleRowDataModel):
        username: str
        password: str

        db = SqliteDict("user.sqlite", autocommit=False)

        @property
        def primary_key(self) -> str:
            return self.username

    user = User(username="alice", password="pwd")
    user.write()

    user1 = User.read("alice")
    print(user1)


Single Table Data Model
------------------------------------------------------------------------------
Each instance of class is a table. Each instance of class could be different tables in the same databases, or different table in different databases.

.. code-block:: python

    import dataclasses
    from sqlitedict import SqliteDict
    from dataclasses_sqlitedict import SingleTableDataModel

    @dataclasses.dataclass
    class User(SingleTableDataModel):
        username: str
        password: str

    db = SqliteDict("user.sqlite", autocommit=False)

    user = User(db=db, username="alice", password="pwd")
    user.write()

    user1 = User.read(db)
    print(user1)
