changes.add_change(someobj, who=request.user)

from changes.models import ChangesMixin
# ...
class SomeModel(ChangesMixin, models.Model)

This mixin will give you some helpful methods:

somemodelinstance.add_change(why='Time for change')

You can also add a change when saving:, who=someuser, why='Changing')

The default behaviour is to not save a change:

The mixin also omits a signal, change_added when a change is added for the object.
