Introduction
|
|
************
|
|
|
|
TinyDB is a lightweight document oriented database optimized for your happiness :)
|
|
It's written in pure Python and has no external dependencies. The target are
|
|
small apps that would be blown away by a SQL-DB or an external database server.
|
|
|
|
TinyDB is:
|
|
|
|
- **tiny:** The current source code has 1800 lines of code (with about 40%
|
|
documentation) and 1600 lines tests.
|
|
|
|
- **document oriented:** Like MongoDB_, you can store any document
|
|
(represented as ``dict``) in TinyDB.
|
|
|
|
- **optimized for your happiness:** TinyDB is designed to be simple and
|
|
fun to use by providing a simple and clean API.
|
|
|
|
- **written in pure Python:** TinyDB neither needs an external server (as
|
|
e.g. `PyMongo <https://api.mongodb.org/python/current/>`_) nor any dependencies
|
|
from PyPI.
|
|
|
|
- **works on Python 3.7+ and PyPy3:** TinyDB works on all modern versions of Python
|
|
and PyPy.
|
|
|
|
- **powerfully extensible:** You can easily extend TinyDB by writing new
|
|
storages or modify the behaviour of storages with Middlewares.
|
|
|
|
- **100% test coverage:** No explanation needed.
|
|
|
|
To dive straight into all the details, head over to the `TinyDB docs
|
|
<https://tinydb.readthedocs.io/>`_. You can also discuss everything related
|
|
to TinyDB like general development, extensions or showcase your TinyDB-based
|
|
projects on the `discussion forum <http://forum.m-siemens.de/.>`_.

Supported Python Versions
|
|
*************************
|
|
|
|
TinyDB has been tested with Python 3.7 - 3.11 and PyPy3.
|
|
|
|
Example Code
|
|
************
|
|
|
|
.. code-block:: python
|
|
|
|
>>> from tinydb import TinyDB, Query
|
|
>>> db = TinyDB('/path/to/db.json')
|
|
>>> db.insert({'int': 1, 'char': 'a'})
|
|
>>> db.insert({'int': 1, 'char': 'b'})
|
|
|
|
Query Language
|
|
==============
|
|
|
|
.. code-block:: python
|
|
|
|
>>> User = Query()
|
|
>>> # Search for a field value
|
|
>>> db.search(User.name == 'John')
|
|
[{'name': 'John', 'age': 22}, {'name': 'John', 'age': 37}]
|
|
|
|
>>> # Combine two queries with logical and
|
|
>>> db.search((User.name == 'John') & (User.age <= 30))
|
|
[{'name': 'John', 'age': 22}]
|
|
|
|
>>> # Combine two queries with logical or
|
|
>>> db.search((User.name == 'John') | (User.name == 'Bob'))
|
|
[{'name': 'John', 'age': 22}, {'name': 'John', 'age': 37}, {'name': 'Bob', 'age': 42}]
|
|
|
|
>>> # Apply transformation to field with `map`
|
|
>>> db.search((User.age.map(lambda x: x + x) == 44))
|
|
>>> [{'name': 'John', 'age': 22}]
|
|
|
|
>>> # More possible comparisons: != < > <= >=
|
|
>>> # More possible checks: where(...).matches(regex), where(...).test(your_test_func)
|
|
|
|
Tables
|
|
======
|
|
|
|
.. code-block:: python
|
|
|
|
>>> table = db.table('name')
|
|
>>> table.insert({'value': True})
|
|
>>> table.all()
|
|
[{'value': True}]
|
|
|
|
Using Middlewares
|
|
=================
|
|
|
|
.. code-block:: python
|
|
|
|
>>> from tinydb.storages import JSONStorage
|
|
>>> from tinydb.middlewares import CachingMiddleware
|
|
>>> db = TinyDB('/path/to/db.json', storage=CachingMiddleware(JSONStorage))
