Extensions to Django for use with MySQL/MariaDB

The dolphin-pony - proof that cute + cute = double cute.

Django-MySQL is a non-inventively named package that helps you use some MySQL/MariaDB-specific features in the world of Django.

What kind of features?

Here’s a short list of what’s inside:

  • QuerySet extensions - ‘smart’ iteration, approx_count for quick estimates of count(), quick pt-visual-explain of the underlying query
  • Handler - quicker reads using MySQL’s built-in NoSQL API
  • Status variable inspection and utility methods
  • User locks - use MySQL as a locking server between your servers

To see them all, check out the exposition at .


Tested with:

  • Python: 2.7, 3.3, 3.4
  • Django: 1.7, 1.8 RC
  • MySQL: 5.5, 5.6 / MariaDB: 5.5, 10.0, 10.1
  • mysqlclient: 1.3.5 (Python 3 compatible version of MySQL-python)

Any combination of these should be good, and also MySQL-python should work since it’s just an older version of mysqlclient.


0.1.9 (2015-04-20)

  • pt_visual_explain no longer executes the given query before fetching its EXPLAIN
  • New pt_fingerprint function that wraps the pt-fingerprint tool efficiently
  • For List fields, the new ListF class allows you to do atomic append or pop operations from either end of the list in a single query
  • For Set fields, the new SetF class allows you to do atomic add or remove operatiosn from the set in a single query
  • The @override_mysql_variables decorator has been introduced which makes testing code with different MySQL configurations easy
  • The is_mariadb property gets added onto Django’s MySQL connection class automatically
  • A race condition in determining the minimum and maximum primary key values for smart iteration was fixed.

0.1.8 (2015-03-31)

  • Add Set and List fields which can store comma-separated sets and lists of a base field with MySQL-specific lookups
  • Support MySQL’s GROUP_CONCAT as an aggregate!
  • Add a functions module with many MySQL-specific functions for the new Django 1.8 database functions feature
  • Allow access of the global and session status for the default connection from a lazy singleton, similar to Django’s connection object
  • Fix a different recursion error on count_tries_approx

0.1.7 (2015-03-25)

  • Renamed connection_name argument to using on Lock, GlobalStatus, and SessionStatus classes, for more consistency with Django.
  • Fix recursion error on QuerySetMixin when using count_tries_approx

0.1.6 (2015-03-21)

  • Added support for HANDLER statements as a QuerySet extension
  • Now tested on Django 1.8
  • Add pk_range argument for ‘smart iteration’ code

0.1.5 (2015-03-11)

  • Added command dbparams for outputting database paramters in formats useful for shell scripts

0.1.4 (2015-03-10)

  • Fix release process

0.1.3 (2015-03-08)

  • Added pt_visual_explain integration on QuerySet
  • Added soundex-based field lookups for the ORM

0.1.2 (2015-03-01)

  • Added get_many to GlobalStatus
  • Added wait_until_load_low to GlobalStatus which allows you to wait for any high load on your database server to dissipate.
  • Added smart iteration classes and methods for QuerySets that allow efficient iteration over very large sets of objects slice-by-slice.

0.1.1 (2015-02-23)

  • Added Model and QuerySet subclasses which add the approx_count method

0.1.0 (2015-02-12)

  • First release on PyPI
  • Locks
  • GlobalStatus and SessionStatus
