loops - Linked Objects for Organization and Processing Services

($Id$)
>>> from zope import component
>>> from zope.traversing.api import getName
First we set up a loops site with basic and example concepts and resources.
>>> from zope.app.testing.setup import placefulSetUp, placefulTearDown
>>> site = placefulSetUp(True)
>>> from loops.organize.setup import SetupManager
>>> component.provideAdapter(SetupManager, name='organize')
>>> from loops.tests.setup import TestSite
>>> t = TestSite(site)
>>> concepts, resources, views = t.setup()
>>> loopsRoot = site['loops']
Stateful Objects
================
Let's start with registering the states definitions and adapters needed.
The states definition (aka 'workflow') is registered as a utility; for
making an object statful we'll use an adapter.
>>> from cybertools.stateful.interfaces import IStatesDefinition, IStateful
>>> from cybertools.stateful.publishing import simplePublishing
>>> component.provideUtility(simplePublishing, IStatesDefinition,
... name='loops.simple_publishing')
>>> from loops.stateful.base import SimplePublishable
>>> component.provideAdapter(SimplePublishable, name='loops.simple_publishing')
We may now take a document and adapt it to IStateful so that we may
check the document's state and perform transitions to other states.
>>> doc01 = resources['d001.txt']
>>> statefulDoc01 = component.getAdapter(doc01, IStateful,
... name='loops.simple_publishing')
>>> statefulDoc01.state
'draft'
>>> statefulDoc01.doTransition('publish')
>>> statefulDoc01.state
'published'
Let's check if the state is really stored in the underlying object and
not just kept in the adapter.
>>> statefulDoc01_x = component.getAdapter(doc01, IStateful,
... name='loops.simple_publishing')
>>> statefulDoc01.state
'published'
