Hello!

I'm pleased to announce version 3.7.0, the first stable release of branch
3.7 of SQLObject.


What's new in SQLObject
=======================

Contributors for this release are Scott Stahl and Christophe Popov.

Features
--------

* Add signals on commit and rollback; pull request by Scott Stahl.

Bug fixes
---------

* Fix SSL-related parameters for MySQL-connector (connector uses
  a different param style). Bug reported by Christophe Popov.

Drivers
-------

* Remove psycopg1. Driver ``psycopg`` is now just an alias for ``psycopg2``.

Tests
-----

* Install psycopg2 from `psycopg2-binary`_ package.

.. _`psycopg2-binary`: https://pypi.org/project/psycopg2-binary/

For a more complete list, please see the news:
http://sqlobject.org/News.html


What is SQLObject
=================

SQLObject is an 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, PostgreSQL, SQLite,
Firebird, Sybase, MSSQL and MaxDB (also known as SAPDB).

Python 2.7 or 3.4+ is required.

Example
=======

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
  '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

Oleg.
