Adds a behavior that tracks down the last user that modified an object

Project description


Adds a behavior that tracks down the last user that modified an object.

The plone.last_modifier behavior that can be added to any dexterity content.

Objects with that behavior will update the last_modifier attribute of the object with the currently authenticated user id:

  • when an object is created

  • every time an ObjectModifiedEvent is fired.

There is a tracking_disabled context manager that can be used to disable tracking. This might come handy, for example during migrations:

from collective.behavior.lastmodifier.behavior import tracking_disabled

with tracking_disabled():


Install collective.behavior.lastmodifier by adding it to your buildout:



eggs =

and then running bin/buildout
