Imports
Lastest release
version 1.0.0 on Mar 15th, 2011

This package implements adapters for adapting any object to ITitle interface.

Let's do some imports we will use later.

>>> import zope.interface
>>> import zope.component
>>> from zope.annotation.interfaces import IAttributeAnnotatable
>>> from zope.dublincore.interfaces import IZopeDublinCore
>>> from zope.container.interfaces import IContained
>>> from cykooz.title.interfaces import ITitle
>>> from cykooz.title import adapters

Let's register the adapters, this is normally done in configure.zcml:

>>> zope.component.provideAdapter(adapters.ClassName2TitleAdapter)
>>> zope.component.provideAdapter(adapters.Contained2TitleAdapter)
>>> zope.component.provideAdapter(adapters.ZDC2TitleAdapter)

Implement test object:

>>> class SomeClass(object):
...     zope.interface.implements(zope.interface.Interface)
>>> some_object = SomeClass()

Get title from class name:

>>> ITitle(some_object).title
u'SomeClass'

Now change the test object so that it provide IContained:

>>> zope.interface.directlyProvides(some_object, IContained)
>>> some_object.__name__ = u'NameInContainer'
>>> ITitle(some_object).title
u'NameInContainer'

Change the test object so that is provide only IAttributeAnnotatable:

>>> zope.interface.directlyProvides(some_object, IAttributeAnnotatable)
>>> IZopeDublinCore(some_object).title
u''

If object do not provide IContained and field 'title' of IZopeDublinCore is empty then ITitle adapter return class name of object:

>>> ITitle(some_object).title
u'SomeClass'

Now change the test object so that it also provide IContained:

>>> zope.interface.alsoProvides(some_object, IContained)
>>> ITitle(some_object).title
u'NameInContainer'

Set field 'title' of IZopeDublinCore:

>>> IZopeDublinCore(some_object).title = u'ZopeDublinCore Title'
>>> IZopeDublinCore(some_object).title
u'ZopeDublinCore Title'

Test adapter:

>>> ITitle(some_object).title
u'ZopeDublinCore Title'
