A pseudo NoSQL database

RunDB

RunDb is not exactly a database. It is similar to TinyDB <https://tinydb.readthedocs.io/en/stable/>__ on storing files as json.

The main point of this library is to help the user on storing and loading data.

Philosophy

• NoSql with tools to simulate relational
• Table are all fully loaded when declared
• Query are done using python
• Data are dict, they all have a unique key as a string

Quick Overview

.. code:: python

    import RunDB
    from pathlib import Path
    from RunDB.tools.serialization import call_kwargs

    # Path to DB folder
    db_path = Path("testRunDB")
    # Create the Database instance
    db = RunDB.Database(db_path)

    # Get or Create User table, specifying the key as login (default is "id")
    # The key is used to find, if not explicitly given, the database id
    User = db.table("user", key="login")

    # Same for Group table
    Group = db.table(
        "group",
        key="name",
        one2many={"users": "user"}
    )

    # Create User 1
    u1 = User.append({"login": "paul"})  # With values

    # without values, 
    u2 = User["Matthieu"]
    u3 = User["Thomas"]

    u1.age = 18
    u2.age = 20
    u3.age = 18

    res = User.filter(lambda user: user.age == 20)

    list(User.records())


    test= Group["test"]
    test.users.append(u1)


    adminGroup = Group.append({
        "name": "admin",  # as the table key is "name", name will be poped
    })


    db["test"]["new"] = {"name": "new data"}  # Quick insert

    # Check if record has attribute age
    "age" in u1  # True

    # Get a dict
    data = dict(u1.items())

    db.dump_all()

Nb: Database are simply Group of Table, We can register Tables from
somewhere else or simply use a Table without Database object

Future
------

-  improve relational
