Introduction

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.

Writing additional views

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>

Extending portlet schema

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
    }
