Hello! I'm pleased to announce version 3.11.0, the first stable release of branch 3.11 of SQLObject. What's new in SQLObject ======================= Features -------- * Continue working on ``SQLRelatedJoin`` aliasing introduced in 3.10.2. When a table joins with itself calling ``relJoinCol.filter(thisClass.q.column)`` raises ``ValueError`` hinting that an alias is required for filtering. * Test that ``idType`` is either ``int`` or ``str``. * Added ``sqlmeta.idSize``. This sets the size of integer column ``id`` for MySQL and PostgreSQL. Allowed values are ``'TINY'``, ``'SMALL'``, ``'MEDIUM'``, ``'BIG'``, ``None``; default is ``None``. For Postgres mapped to ``smallserial``/``serial``/``bigserial``. For other backends it's currently ignored. Feature request by Meet Gujrathi at https://stackoverflow.com/q/77360075/7976758 For a more complete list, please see the news: http://sqlobject.org/News.html What is SQLObject ================= SQLObject is a free and open-source (LGPL) Python object-relational mapper. Your database tables are described as classes, and rows are instances of those classes. SQLObject is meant to be easy to use and quick to get started with. SQLObject supports a number of backends: MySQL/MariaDB (with a number of DB API drivers: ``MySQLdb``, ``mysqlclient``, ``mysql-connector``, ``PyMySQL``, ``mariadb``), PostgreSQL (``psycopg2``, ``PyGreSQL``, partially ``pg8000`` and ``py-postgresql``), SQLite (builtin ``sqlite``, ``pysqlite``); connections to other backends - Firebird, Sybase, MSSQL and MaxDB (also known as SAPDB) - are less debugged). Python 2.7 or 3.4+ is required.

from sqlobject import *
sqlhub.processConnection = connectionForURI('sqlite:/:memory:')
class Person(SQLObject): ... fname = StringCol() ... mi = StringCol(length=1, default=None) ... lname = StringCol() ... Person.createTable()
Use the object::
p = Person(fname="John", lname="Doe") p <Person 1 fname='John' mi=None lname='Doe'> p.fname 'John' p.mi = 'Q' p2 = Person.get(1) p2 <Person 1 fname='John' mi='Q' lname='Doe'> p is p2 True
Queries::
p3 = Person.selectBy(lname="Doe")[0] p3 <Person 1 fname='John' mi='Q' lname='Doe'> pc = Person.select(Person.q.lname=="Doe").count() pc 1
