Handles the lifecycle of objects for the Horae resource planning system

Project description


horae.lifecycle handles the lifecycle of objects for the Horae resource planning system. It stores the creator, creation_date, modifier and modification_date of objects implementing horae.lifecycle.interfaces.ILifecycleAware. Additionally it provides a viewlet displaying the collected information in context and a storage for latest objects of a user which tracks what objects were changed by a given user.


The easiest way to activate the functionality provided by horae.lifecycle is to subclass from the provided mix in class horae.lifecycle.lifecycle.LifecycleAwareMixin:

import grok

from horae.lifecycle import lifecycle

class SampleContent(grok.Model, lifecycle.LifecycleAwareMixin):
    """ Sample content aware of his lifecycle


The latest storage is provided as an adapter implementing horae.lifecycle.interfaces.ILatest and adapting a principal. There is a convenience adapter adapting the request available which returns the storage for the current user:

from horae.lifecycle import interfaces

class SampleView(grok.View):

    def latest(self):
        latest = interfaces.ILatest(self.request)
        return latest.objects()
