A Plone Portlet which displays custom recent types

Project description

Overview

A Plone Portlet which does an adapter lookup to fetch the portal type to use in the query for recently changed portlets.

Rationale

This is scratching an itch of a customer, which wants to display only recent “news” on a news page etc. Instead of hard-coding the portal type, we do a adapter lookup.

Usage

Users then can register adapters like:

<adapter
    for=".interfaces.INewsArea
         zope.publisher.interfaces.browser.IBrowserRequest
         zope.publisher.interfaces.browser.IBrowserView
         "
    provides="inquant.portlet.contextualrecentitems.interfaces.ITypeNameProvider"
    factory=".adapters.FeedItemTypeProvider"
    />

<five:implements
    class="Products.feedfeeder.content.folder.FeedfeederFolder"
    interface=".interfaces.INewsArea"
    />

And have the actual adapter look like:

class FeedItemTypeProvider(object):
    def __init__(self, context, request, view):
        pass
    type = "FeedFeederItem"

The portlet renderer does a queryMultiAdapter on the context, the request and the view. Thus, it’s possible to have a different portlet for each view of your content. This is useful for search pages registered on the site root:

<adapter
    for="zope.interface.Interface
         zope.publisher.interfaces.browser.IBrowserRequest
         Products.BabpnProducts.browser.search.BabpnBOSearchView"
    provides="inquant.portlet.contextualrecentitems.interfaces.ITypeNameProvider"
    factory=".adapters.BizOpTypeProvider"
    />

class BizOpTypeProvider(object):
    def __init__(self, context, request, view):
        pass
    type = "BusinessOpportunity"

That way, the recent changes portlet only shows items which match your search page.

Of course, if no adapter is found, the portlet falls back to its normal behavior like the standard plone recently changed portlet.
