cykooz.title 1.0.0

此软件包实现了将任何对象适配到ITitle接口的适配器。

让我们导入我们稍后会用到的模块。

>>> 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

让我们注册适配器，这通常在configure.zcml中完成

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

实现测试对象

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

从类名获取标题

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

现在更改测试对象，使其提供IContained

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

更改测试对象，使其仅提供IAttributeAnnotatable

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

如果对象不提供IContained且IZopeDublinCore的‘title’字段为空，则ITitle适配器返回对象的类名

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

现在更改测试对象，使其也提供IContained

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

设置IZopeDublinCore的‘title’字段

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

测试适配器

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