Setting up a loops Site and Utilities
=====================================
Let's do some basic set up
>>> from zope import component, interface
>>> from zope.traversing.api import getName
>>> from zope.app.testing.setup import placefulSetUp, placefulTearDown
>>> site = placefulSetUp(True)
and build a simple loops site with a concept manager and some concepts
(with a relation registry, a catalog, and all the type machinery - what
in real life is done via standard ZCML setup or via local utility
configuration):
>>> from loops.integrator.testsetup import TestSite
>>> t = TestSite(site)
>>> concepts, resources, views = t.setup()
>>> loopsRoot = concepts.getLoopsRoot()
Options Adapters
================
Global and site options
-----------------------
>>> from cybertools.meta.interfaces import IOptions
>>> opt = IOptions(loopsRoot)
>>> opt
<loops.config.base.LoopsOptions object ...>
>>> str(opt)
''
We now use the loops root object's options field to define
some options.
>>> loopsRoot.options = ['useVersioning', 'organize.tracking:changes, access']
>>> opt = IOptions(loopsRoot)
>>> opt.organize.tracking
['changes', 'access']
>>> opt.useVersioning
True
>>> print(opt)
useVersioning=True
organize(tracking=['changes', 'access'])
If we query an option that is not defined on the site level we get a
dummy element that corresponds to False.
>>> opt.i18n.languages
<AutoElement 'languages'>
>>> bool(opt.i18n.languages)
False
We can use a utility for providing global settings.
>>> from cybertools.meta.interfaces import IOptions
>>> globalOpt = component.getUtility(IOptions)
>>> globalOpt.i18n.languages = ['en', 'de']
>>> globalOpt.i18n.languages
['en', 'de']
If we call the site options with the key we want to query the global
options will be used as a fallback.
>>> opt('i18n.languages')
['en', 'de']
