Vocabulary

在 plone.app.vocabulary 利用 zope.schema.vocabulary 實作了基本辭彙當作延伸開發的範例。

Country ISO3166 collective.address

原理與建立方式

選項式欄位的建立方式有兩大類。單選欄位 Selection Field 使用 Choice 欄位型別，範例是 myChoice = schema.Choice(...)。多選欄位 MultiSelection Field 可以使用 List、Tuple、Set、Frozenset 欄位型別，再搭配 value_type 參數，範例是 myList = schema.List(..., value_type=schema.Choice(...))。

Choice 型別需要指定一種選項來源：

• values can be used to give a list of static values;
• source can be used to refer to an IContextSourceBinder or ISource instance;
• vocabulary can be used to refer to an IVocabulary instance or (more commonly) a string giving the name of an IVocabularyFactory named utility.

    enabled_content_types = schema.List(
        title=_(u'Enabled Content Types'),
        description=_(u'Only objects of these content types will display glossary terms.'),
        required=False,
        default=DEFAULT_ENABLED_CONTENT_TYPES,
        # we are going to list only the main content types in the widget
        value_type=schema.Choice(
            vocabulary=u'collective.glossary.PortalTypes'),
)
