Autocomplete values (vocabulary?) for TokenInputFieldWidget

[jperals]

TokenInputFieldWidget is supposed to provide an autocomplete functionality that suggest values to the user as (s)he types, but where are these values fetched from?

In Dexterity, only fields of type Choice can have a vocabulary[1], but your readme[2] seems to say that the TokenInputFieldWidget can only be used with (a List of) TextLine fields.

I tried using Choice fields with the TokenInputFieldWidget instead of TextLine fields, and confirmed that it doesn't work.

@flecox could you please check this?

@jperals Currently it's hardcoded in token_input_widget.py:

values = self.context.portal_catalog.uniqueValuesFor('Subject')
old_values = self.context.Subject()

I've done something similar in this package:

• https://github.com/abstract-open-solutions/abstract.z3cform.usertokeninput

Unfortunately it's not completed and well documented but it could be useful for you.
If you are interested in I can integrate this widget in c.z3cform.widgets package

@gborelli Thank you
But unfortunately I'm looking for a different behavior.
I have a vocabulary as source.
I'm trying to tweak the collective.z3cform.widgets, currently it's just a prove of concept. So I'm not sure, that we need the tokeninput widget.
And I do not use it for DX type, it's just a notification z3c form.

@frapell any comments?

Adding more info here:

1. The widget only supports the Subject (Tags) field. There isn't a way to use it with fields with vocabularies
2. All keywords are loaded into the page. For instance, if you have a site with 5000 keywords, all of them will be listed inline in the edit view for the content item

@maethu did you succeed on your proof-of-concept?

[maethu]

@hvelarde Unfortunately not.
I found select2 jQuery widget really useful and made a test implementation hier
I wrote my own small template
As source I defined a new vocabulary
It's well tested, but not production ready (some performance issues if the user source is a ldap user folder and other small issues)

It's possible to search groups/users and add new entries if you wand.

I wasn't able to implement it as a proper widget with vocabulary source.

@maethu see #35

I think the JSON bowser view could be the key to support this.
