!!! THIS IS AN EXPERIMENTAL FORK - DO NOT USE FOR PRODUCTION !!!
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.
Pictures say more than words do - so first a screenshot of current work:
This fork tries to handle several issues we discovered (and still discovering) while building a huge multilingual site on plone.app.contenttypes and plone.app.multilingual and Plone 4.3.
You'll have multiple content objects providing INavigationRoot when using plone.app.multilingual because of it's shared folder.
Idea is to implement a library like selection to switch between Language folders and Shared folders. You can register your own library folders by adapting ILibraryProvider interface and register in zcml as an adapter.:
@adapter(IContentTreeWidget)
@implementer(ILibraryProvider)
def shared_libs(widget):
"""TODO: Refactor to allow binding on special fields"""
catalog = getToolByName(widget.context, 'portal_catalog')
return [{'label': item.Title, 'query': item.getPath()}
for item in catalog(object_provides=INavigationRoot.__identifier__)]See adapters/libraries.py for more details.
Preview pane was refactored to support registering custom Preview adapters on different types. I really would like to see new multiadapters for File and Images displaying contenttype and size information.:
class DefaultPreviewAdapter(object):
implements(IContentTreeWidgetPreview)
template = ViewPageTemplateFile('default.pt')
def __init__(self, context, widget):
self.context = context
self.request = widget.request
self.widget = widget
def title(self):
return self.context.Title()
def description(self):
return self.context.Description()
def __call__(self):
return self.template()See adapters/preview.py for more details.
- Run egg-contained buildout
- Start up your instance
- Create new plone site
- Setup up some languages in
plone.app.multilingualcontrolpanel - Create some Demo content
- Open browser and go to http://localhost:8080/Plone/en/@@test-tree-widget
