plone.formwidget.contenttree 1.0.4

AJAX selection widget for Plone

Introduction

plone.formwidget.contenttree is a z3c.form widget for use with Plone. It uses the jQuery Autocomplete widget, and has graceful fallback for non- Javascript browsers.

There is a single-select version (AutocompleteSelectionFieldWidget) for Choice fields, and a multi-select one (AutocompleteMultiSelectionFieldWidget) for collection fields (e.g. List, Tuple) with a value_type of Choice.

When using this widget, the vocabulary/source has to provide the IQuerySource interface from z3c.formwidget.query and have a search() method.

Example Usage:

from zope.component import adapts
from zope.interface import Interface, implements
from zope import schema

from plone.z3cform import layout

from z3c.form import form, button, field

from plone.formwidget.contenttree import ContentTreeFieldWidget
from plone.formwidget.contenttree import MultiContentTreeFieldWidget
from plone.formwidget.contenttree import PathSourceBinder


class ITestForm(Interface):

    buddy = schema.Choice(title=u"Buddy object",
                          description=u"Select one, please",
                          source=PathSourceBinder(portal_type='Document'))

    friends = schema.List(
        title=u"Friend objects",
        description=u"Select as many as you want",
        value_type=schema.Choice(
            title=u"Selection",
            source=PathSourceBinder(portal_type='Document')))


class TestAdapter(object):
    implements(ITestForm)
    adapts(Interface)

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

    def _get_buddy(self):
        return None
    def _set_buddy(self, value):
        print "setting", value
    buddy = property(_get_buddy, _set_buddy)

    def _get_friends(self):
        return []
    def _set_friends(self, value):
        print "setting", value
    friends = property(_get_friends, _set_friends)


class TestForm(form.Form):
    fields = field.Fields(ITestForm)
    fields['buddy'].widgetFactory = ContentTreeFieldWidget
    fields['friends'].widgetFactory = MultiContentTreeFieldWidget
    # To check display mode still works, uncomment this and hit refresh.
    #mode = 'display'

    @button.buttonAndHandler(u'Ok')
    def handle_ok(self, action):
        data, errors = self.extractData()
        print data, errors

TestView = layout.wrap_form(TestForm)

Changelog

1.0.4 (2011-10-04)

• fix _getBrainByValue to check if value is traversable first so we can provide the correct token. [vangheem]

1.0.3 (2011-09-24)

• Add zh_CN translation. [jianaijun]

1.0.2 (2011-07-02)

• Fix regression that broke the browsing with JQuery < 1.4. [davisagli]

1.0.1 (2011-05-16)

• Make placeholder terms for hidden / missing items, so that you can still see something in the editing interface and not accidentally remove them. Ideally we should say if a page is invisible or missing, but not today. [lentinj]

• Use javascript function from plone.formwidget.autocomplete to add new input boxes, make javascript as clone-safe (when making new rows in datagridfield) as possible [lentinj]

• Just use full widget name in ++widget++ URL, don’t try and strip form prefix off. If within a subform, this is the wrong thing to do and the traverser now supports stripping the initial ‘form.widgets’ [lentinj]

• Workaround for sources being used without being bound first. [lentinj]

• Check the request for context before falling back to getSite() [lentinj]

• Add a UUIDSource that stores plone.uuid pointers to content. [lentinj]

• Use tokens as full URL of content, move all token<->value operations into the source. Rename methods so that actually-public methods have public names [lentinj]

• Alter terms so that token is the full path to an item, value is the path without portal_url that is stored in the DB. This means all the path parsing can be kept within the source. [lentinj]

• _filter is used outside the source, so not an internal helper function anymore. [lentinj]

1.0 (2011-04-30)

• Made compatible with Plone 4.1 by loading the permissions.zcml from Products.CMFCore (only when plone.app.upgrade is available, to keep compatibility with Plone 3, if we currently have that). [maurits]

• Improved CSS for selected items to make them more evident in the Sunburst theme. [davisagli]

• Add content type CSS class to items in the navtree so that icons are shown in Plone 4. [davisagli]

1.0b3 (2011-02-11)

• Use zope.i18n.translate instead of translation_service, since translation_service was removed in plone4. [jbaumann]

1.0b2 (2010-08-25)

• Fall back to the site to perform content-related operations if the context is not wrapped into an acquisition chain. [dukebody]

• Compute the view name as the request URL left-stripped the content absolute URL. [dukebody]

• Make it possible to restrict the field to objects below a path The constructor of ObjPathSource takes a path keyword argument with a PathIndex catalog query. This argument filters objects outside of this path. If the navigation_tree_query does not have a path argument, the path is also copied into this query. [gaudenzius]

• Update widget in the contenttree-fetch browser view The widget.update() call rebinds to source which previously was only bound during traversal. This avoids problems with sources that only work after security is applied. [gaudenzius]

1.0b1 - 2010-04-19

• Adjusted styles so the widget looks reasonable with Plone 4’s sunburst theme. [davisagli]

• Fix icons in CMF 2.2. This closes http://code.google.com/p/dexterity/issues/detail?id=111 [davisagli]

• Make the widget work properly on Zope 2.12 [optilude]

• Add a template for HIDDEN_MODE. [csenger]

• Convert all strings in a new navtree node into unicode using the site encoding to render non-ascii characters in the widget. [csenger]

• Added message IDs for translations and added locales directory with german translations. [jbaumann]

1.0a5 - 2009-08-02

• Don’t filter children of non-queriable parent types (e.g. Large Plone Folders). [optilude]

1.0a3 - 2009-07-12

• Apply patch from Gerhard Weis to make the lightbox play nicer with CSS z-indexes. [optilude]

1.0a3 - 2009-06-29

• Fix security validator to work properly on add views and other views using namespace traversal (++add++…) [optilude]

1.0a2 - 2009-06-28

• Fix display widgets. [optilude]

• Import SitemapNavtreeStrategy conditionally so it doesn’t break on Plone trunk. [davisagli]

1.0a1 - 2009-04-17

• Initial release
