Automatically save only changed model data.

Project description

https://img.shields.io/pypi/v/django-save-the-change.svg https://travis-ci.org/karanlyons/django-save-the-change.svg?branch=master https://codecov.io/github/karanlyons/django-save-the-change/coverage.svg?branch=master

Save The Change takes this:

>>> lancelot = Knight.objects.get(name="Sir Lancelot")
>>> lancelot.favorite_color = "Blue"
>>> lancelot.save()

And does this:

UPDATE "roundtable_knight"
SET "favorite_color" = 'Blue'

Instead of this:

UPDATE "roundtable_knight"
SET "name" = 'Sir Lancelot',
    "from" = 'Camelot',
    "quest" = 'To seek the Holy Grail.',
    "favorite_color" = 'Blue',
    "epithet" = 'The brave',
    "actor" = 'John Cleese',
    "full_name" = 'John Marwood Cleese',
    "height" = '6''11"',
    "birth_date" = '1939-10-27',
    "birth_union" = 'UK',
    "birth_country" = 'England',
    "birth_county" = 'Somerset',
    "birth_town" = 'Weston-Super-Mare',
    "facial_hair" = 'mustache',
    "graduated" = true,
    "university" = 'Cambridge University',
    "degree" = 'LL.B.',
