Portlet Management
每個目錄或頁面，都可以設定資訊方框，在網址後面加上 /@@manage-portlets 就能進入設定介面。
調整資訊方框設定值
調整網站根目錄的 portlet 設定值，取消右邊方框的顯示。
系統預設是在網頁右邊顯示 news portlet 和 event portlet，目前移到左邊。

<img src="" alt=""
tal:define="item_object obj/getObject;"
tal:condition="exists:item_object/image_thumb"
tal:replace="strcture python: path('nocall:item_object/tag')(scale='thumb', css_class='tileImage')" />

模組開發
資訊方框的元件通常包括 Schema Interface、Assignment Class、Add Form、Edit Form、Portlet Renderer。
>>> import zope.component >>> site = app.site # or your plone site >>> manager = zope.component.queryUtility(IPortletManager, name='plone.leftcolumn', context=site)
>>> list(manager.keys()) [u'content_type', u'group', u'user'] >>> list(manager['content_type'].keys()) [u'ExampleContent', u'ExampleDocument', ...] >>> del manager['content_type'][u'ExampleContent'] >>> import transaction >>> transaction.commit()
If you have specific portlets you need to remove, you have to reinstall the product that contains your broken portlets, as you will get an error if you try to do this:
>>> list(manager['content_type'][u'ExampleDocument'].items() [(u'example_portlet', ), ... >>> del manager['content_type'][u'ExampleContent'][u'example_portlet'] Traceback (most recent call last): ... AttributeError: __parent__
Portlet 是 plone.portlets.interfaces.IPortletType 註冊為 local utility 形式，下列範例可以檢查註冊狀況：
p = app.unrestrictedTraverse("path to your site object")
from plone.portlets.interfaces import IPortletType
from zope.app.component.hooks import setSite
setSite(p)
cr = p.getSiteManager()
portlet_types = [r.name for r in cr.registeredUtilityes() if r.provided==IPortletType]
print portlet_types
新增 CSS 欄位範例: collective.portlet.embed
Ordering
調整顯示順序的方法 Programmatically Replacing
Extend Navigation Portlet ftw.treeview (2014-03-05 tried, with no screen appearing)
在 configure.zcml 裡，除了註冊 Extension Profile 之外，還有一個 Retriever 註冊動作：
<adapter factory=".portlets.PortletPageRetriever" />
Portlet Refresh Passing the URL of the Context
Programmatically Remove Broken Portlets
Expand / Collapse for Navigation Portlet
plone.app.portlets 2.4.5 版本在執行 export 時，並不會完整處理子目錄的設定值。

portlets/analyticsportlet.py
def getJavascript(self):
"""
Returns a list of AnalyticsReportResults objects for the selected reports.
"""
return self.async_loader.getJavascript(self.data.reports, self.data.profile)
Conditional Display
例子之一，在點選 Share 頁籤 (執行 @@sharing) 不想顯示 Portlet 的話，至少有兩種方法，一是 CSS display: none 方式，二是修改 Main Template 的 sl 和 sr 條件。
tal:define="sl python:plone_view.have_portlets('plone.leftcolumn', view);
sr python:plone_view.have_portlets('plone.rightcolumn', view);"
Plone 5 Compatibility
使用 z3c.form 取代 formlib，不改程式碼的話，可能會遇到 NotImplementedError: The class deriving from AutoExtensibleForm must have a 'schema' property 錯誤，由於 Plone 5 的 AddForm EditForm 需要 schema 屬性值，在 Plone 4 是使用 form_fields，最簡單的方式是增加 schema 設定值，內容就是 Interface：
class AddForm(base.AddForm):
+ schema = IExamplePortlet
form_fields = form.Fields(IExamplePortlet)
def create(self, data):
return Assignment(**data)

plone.app.portlets now contains the fix that allows you to delete broken portlet assignment
