Vocabulary

分成 Static Vocabulary, Dynamic Source, Parameterised Source, Named Vocabulary 不同類型,系統透過 plone.app.vocabularies 提供常用的辭典集。

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

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.

程式碼範例 collective.glossary

    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'),
)

Sample Codes: fourdigits.tracker collective.weather

def update(self):
    weather_utility = getUtility(IWeatherUtility)
    factory = getUtility(
        IVocabularyFactory, name='collective.weather.Locations')
    vocab = factory(self.context)
    self.current_city = None
    if self.data.location in vocab:
        location = vocab.by_value[self.data.location]
        self.current_city = {'location_id': location.value, 'name': location.title}

    self.weather_info = None
    if not self.current_city is None:
        weather_utility.update_weather_info(self.current_city['location_id'])
        self.weather_info = weather_utility.get_weather_info(self.current_city)
