Extend/modify pattern (relateditems) options site-wide [solved]

Plone Support Add-on Development

Is there a way to modify patterns options for the complete site - for all "relateditems" fields?
I want to extend the Favorites-Dropdown...

What I already tried:
1- Resource-Registry - pattern options
Write options to body-Attributes, does not work. Settings in Widgets are used

2- Adapt IPatternsSettings (from CMFPlone) does not work, writes to body-Attributes. Settings in Widgets are used

Ok, its working now :wink:

Not working actually:

  • translation of dropdown items
  • Add items without "copying" default items
  • Update/Change default items

This is my working code:

configure.zcml

<adapter
    for="* * *"
    factory=".adapters.PatternsAttributes"
    provides="Products.CMFPlone.interfaces.IPatternsSettings"
    name="patternslib" />

adapters .py

# -*- coding: utf-8 -*-
# Standard Library
import json

# Plone
from plone import api
from Products.CMFPlone.utils import get_portal

# Package
from . import message_factory as _


class PatternsAttributes(object):

    def __init__(self, context, request, field):
        self.request = request
        self.context = context
        self.field = field

    def __call__(self):

        portal = get_portal()
        portal_url = portal.absolute_url()
        root = '/'.join(
            api.portal.get_navigation_root(self.context).getPhysicalPath())
        current_path = self.context.absolute_url()[len(portal_url):]

        current = dict({
            'path': current_path,
            'title': _(u'Current Content')
        })

        nav_root = dict({
            'path': root,
            'title': _(u'Frontpage')
        })
        mediacenter = dict({
            'path': '{}/mediathek'.format(root),
            'title': _(u'Media Center')
        })

        options = list()
        options.append(current)
        options.append(nav_root)
        options.append(mediacenter)

        favorites = dict({'favorites': options})

        return {'data-pat-relateditems': json.dumps(favorites)}
