Behaviors

手動啟用或停用的方式,是到 @@dexterity-types 選擇型別,再由 Behaviors 頁籤裡勾選,儲存後就生效。以 Versioning 為例,啟用後會出現在表單最下方。

利用 updateFields 技巧,可以針對特定型別啟用功能。

RichText

內容格式轉換

from plone.app.textfield.interfaces import ITransformer

transformer = ITransformer(context)
transformedValue = transformer(context.body, 'text/plain')

plone.app.contenttypes RichText 檢查是否安裝的判斷範例

import pkg_resources
try:
    pkg_resources.get_distribution('plone.app.textfield')
    from plone.app.textfield.interfaces import IRichTextValue
except (pkg_resources.DistributionNotFound, ImportError):
    HAS_PLONE_APP_TEXTFIELD = False
else:
    HAS_PLONE_APP_TEXTFIELD = True

Could not adapt plone.dexterity.content.Container to interfaces.IPrimaryFieldInfo: Name from File Name

Schema 資料的儲存方式有 Annotation 和 Attribute 兩種。

應用情境 建立和註冊: collective.gtags 範例

IEventRecurrence 欄位是 recurrence

IEventLocation 欄位是 location

IEventAttendees 欄位是 attendees

IEventContact 欄位是 contact_name, contact_email, contact_phone, event_url

Navigation

Navigation Root: Microsites example: telesur.specialreport

Exclude From Navigation 預設值由 ContextAware Default Factory 取得

<adapter
  for="*"
  factory=".exclfromnav.default_exclude_false" />

Behavior 不能被套用在 Archetypes 裡,但可以自行撰寫 Adapter 納入功能: collective.workspace

讓 News Item 變成目錄式 Folderish collective.folderishtypes PLIP 20144: Folderish Types

Versioning

表單下方通常會看到 Change Note 欄位,預設是由 Versioning 控制,底層程式是由 CMFEditions 負責。

Name Chooser

plone.app.contentrules/namechooser.py

WARNING plone.behavior Specifying 'for' in behavior 'Multilingual Support' if no 'factory' is given has no effect and is superfluous.

plone.app.contenttypes/behaviors/thumb_icon.py

collective.geolocationbehavior

Specific Interface Registry 卻沒有限制的效果

WARNING plone.behavior Specifing 'for' in behavior 'xxx' if no 'factory' is given has no effect and is superfluous. 把 for="plone.dexterity.interfaces.IDexterityContent" 移除就能解決
