SQLObject 3.10.2

I'm pleased to announce version 3.10.2, a minor feature release
and the second bugfix release of branch 3.10 of SQLObject.

What's new in SQLObject

The contributor for this release is Igor Yudytskiy. Thanks!

Minor features

* Class ``Alias`` grows a method ``.select()`` to match ````.

Bug fixes

* Fixed a bug in ``SQLRelatedJoin`` in the case where the table joins with
itself; in the resulting SQL two instances of the table must use different
aliases. Thanks to Igor Yudytskiy for providing an elaborated bug report.

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``, partially ``supersqlite``); connections to other backends
- Firebird, Sybase, MSSQL and MaxDB (also known as SAPDB) - are less

Python 2.7 or 3.4+ is required.

Developer Guide:



$ pip install sqlobject

Create a simple class that wraps a table::

>>> 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
>>> p.mi = 'Q'
>>> p2 = Person.get(1)
>>> p2
<Person 1 fname='John' mi='Q' lname='Doe'>
>>> p is p2


>>> p3 = Person.selectBy(lname="Doe")[0]
>>> p3
<Person 1 fname='John' mi='Q' lname='Doe'>
>>> pc ="Doe").count()
>>> pc
