relationchoice not working ...

[iham]

from plone.app.vocabularies.catalog import CatalogSource
from z3c.relationfield.schema import RelationChoice
from zope import schema
from zope.interface import Interface

from collective.z3cform.datagridfield import DataGridFieldFactory
from collective.z3cform.datagridfield import DictRow
from plone.autoform import directives
from plone.supermodel import model

class IItemRow(Interface):
    note = schema.TextLine(
        title=u'Note',
        required=True,
        default=u'',
    )
    events = RelationChoice(
        title=u'Event',
        source=CatalogSource(portal_type=['Event']),
        required=True,
    )

class IEventsGroup(model.Schema):
    directives.widget(employees=DataGridFieldFactory)
    employees = schema.List(
        title=u'A list of events with notes.',
        required=False,
        value_type=DictRow(
            title=u'Event',
            schema=IEventRow,
        )
    )

IEventsGroup is a globally addable contenttype.

the widget gets displayed, but when clicking in the relationchoice widget i get a spinner and no result. calling the view "getSource" i get {"error": "Vocabulary lookup not allowed."}
this seems to occur as self.context.context has NO_VALUE

any help?

If you want to make use of the related items widget, I'd try not to use a CatalogSource but the following:

# -*- coding: utf-8 -*-
from collective.z3cform.datagridfield import DataGridFieldFactory
from collective.z3cform.datagridfield import DictRow
from plone.app.z3cform.widget import RelatedItemsFieldWidget
from plone.autoform import directives
from plone.supermodel import model
from z3c.relationfield.schema import RelationChoice
from zope import schema
from zope.interface import Interface


class IEventRow(Interface):
    note = schema.TextLine(
        title=u'Note',
        required=True,
        default=u'',
    )

    directives.widget(
        'events',
        RelatedItemsFieldWidget,
        pattern_options={
            'selectableTypes': ['Event'],
        }
    )
    events = RelationChoice(
        title=u'Event',
        vocabulary='plone.app.vocabularies.Catalog',
        required=True,
    )


class IEventsGroup(model.Schema):
    directives.widget(employees=DataGridFieldFactory)
    employees = schema.List(
        title=u'A list of events with notes.',
        required=False,
        value_type=DictRow(
            title=u'Event',
            schema=IEventRow,
        )
    )

@iham did you get this working? I ran into the same problem today using the current master that includes #71).

[iham]

@pbauer sadly: no. even after hours of desperation and agony ;)

i guess this is broken by concept as complex fields using context don't work. there is no context, so no way to get a catalog, a portal_root or anything at all.

i'd say: YAFOWIL as @rnixx and @jensens are working on that and more and more fields/widgets/forms and types start looking good and useable. this will allow all sorts of complex fields (compounds) and sorting works like a charm (better than z3c.form) and no change in how to write behaviors, forms, ...

Fixed by #150 👍
