horae.lifecycle 1.0a1

Handles the lifecycle of objects for the Horae resource planning system

Introduction

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.

Usage

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
    """

Latest

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()
