如何将 Stock Portlet（来自 plone.app.portlets）添加到我的自定义 Portlet 管理器？
使用 plone.org 上的文档与论坛中的一些内容一起，我能够在 Plone 4.0.8 中的内容下方获得自定义 portlet 管理器。实际上，目标是在内容下方有 4 个自定义管理器，如仪表板一样排列。
不管怎样，我的经理只允许我添加静态和集合 portlet。查看代码后，我发现当系统填充“添加新 portlet”下拉列表时，它会循环遍历所有 portlet。然后，它循环检查每个 portlet 的“for_”属性，以查看接口是否由我的 portlet 管理器自己提供。
def getAddablePortletTypes(self):
addable = []
for p in getUtilitiesFor(IPortletType):
# BBB - first condition, because starting with Plone 3.1
#every p[1].for_ should be a list
if not isinstance(p[1].for_, list):
logger.warning("Deprecation Warning ..." % p[1].addview)
if p[1].for_ is None or p[1].for_.providedBy(self):
addable.append(p[1])
elif [i for i in p[1].for_ if i.providedBy(self)]:
addable.append(p[1])
return addable
如何将经理的接口添加到每个 portlet 的“for_”接口列表中？
Using the documentation on plone.org along with some in the forum, I was able to get a custom portlet manager below my content in Plone 4.0.8. The goal, actually, is to have 4 custom managers below the content arranged like the dashboard.
Anyway, my manager only allows me to add static and collection portlets. After looking around in the code, I found that when the system goes to populate that 'Add new portlet' dropdown, it loops through all of the portlets. Then, it loops through each portlet's 'for_' attribute checking to see if the interfaces are provided by self--my portlet manager.
def getAddablePortletTypes(self):
addable = []
for p in getUtilitiesFor(IPortletType):
# BBB - first condition, because starting with Plone 3.1
#every p[1].for_ should be a list
if not isinstance(p[1].for_, list):
logger.warning("Deprecation Warning ..." % p[1].addview)
if p[1].for_ is None or p[1].for_.providedBy(self):
addable.append(p[1])
elif [i for i in p[1].for_ if i.providedBy(self)]:
addable.append(p[1])
return addable
How do I add my manager's interface to each portlet's 'for_' list of interfaces?

您的 评论可能是最好的方法。这里的关键是 portlet 本身注册到 portlet 管理器接口，以及上下文、层等的其他接口。例如，另一种方法是在 profile/default/portlets.xml 中添加额外的注册。将每个您想要添加的 portlet 文件添加到您的 portlet 管理器界面：
不过，您的方式可能是最好的，因为听起来您正在创建一个柱状 portlet 管理器。但是，您可以从基类中删除 IPortletManager，因为 IColumn 已经对其进行了子类化。
Your comment is probably the best way to do this. The crux here is that portlets themselves are registered to a portlet manager interface, among other interfaces for contexts, layers, etc.. Another way to do this, for example, would be to add additional registrations in your profiles/default/portlets.xml file to your portlet manager interface for each of the portlets you want addable:
Your way is probably best, however, since it sounds like you are creating a columnar portlet manager. You could remove IPortletManager from the base classes, however, since IColumn already subclasses it.
