The collectionmultiview portlet is a collection portlet which supports multiple view modes. It inherits the built-in plone.portlet.collection and extend it with view adapters support.
Creating an additional view is as simple as writing a class which inherits from BaseRenderer, and register it as a named adapter
Sample code:
from collective.portlet.collectionmultiview import BaseRenderer
from zope.app.pagetemplate.viewpagetemplatefile import ViewPageTemplateFile
class MyCustomRenderer(BaseRenderer):
title = 'My Custom Renderer'
template = ViewPageTemplateFile('path/to/template.pt')ZCML:
<configure
xmlns="http://namespaces.zope.org/zope">
<adapter name="mycustomrenderer"
factory=".package.MyCustomRenderer"/>
</configure>You can also extend the portlet schema with additional fields by setting the 'schema' attribute in the renderer class.
Sample code:
from collective.portlet.collectionmultiview import BaseRenderer
from zope.app.pagetemplate.viewpagetemplatefile import ViewPageTemplateFile
from zope import schema
from zope.interface import Interface
from plone.app.form.widgets.wysiwygwidget import WYSIWYGWidget
class IExtraFields(Interface):
my_extra_field = schema.Text(title=u'Extra field')
class MyCustomRenderer(BaseRenderer):
title = 'My Custom Renderer'
schema = IExtraFields
template = ViewPageTemplateFile('path/to/template.pt')
#optional
custom_widgets = {
'my_extra_field': WYSIWYGWidget
}
