Track changes to your storm model objects with stormchaser.
Create a history table to store changes in:
>>> from storm.locals import *
>>> database = create_database('sqlite:')
>>> store = Store(database)
>>> store.execute("""
CREATE table history (
id INTEGER PRIMARY KEY AUTOINCREMENT,
ref_class VARCHAR(200),
ref_pk VARCHAR(200),
ref_attr VARCHAR(200),
new_value VARCHAR(200),
ctime DATETIME,
user VARCHAR(200)
)""")Now configure a Changelog class that uses the history table:
>>> changelog_cls = Changelog.configure(table='history')And add it to your model class columns as a validator:
>>> class Article(object):
... __storm_table__ = 'articles'
... content = Unicode(validator=ChangelogTracker(changelog_cls))
...
