Collections and Vocabulary Values

[Khairil Yusof-4]

Using ATVocabularyManager for my vocabulary fields.

By indexing fields in catalog and adding metadata to portal_atct the
fields are showing correctly as options in Collection types.

The problem is that they're displaying the Keys and not Values of my
vocabularies.

What's the best way to make Collections automatically return a more
friendly and useful value, instead of keys?

Dear Khairil Yusof,

I've not implemented this myself but I did look briefly at what would be
required, to be able to show more user friendly values in the Collection
criteria screen, for a previous project.

Implementing and using a custom criteria type based on
ATSelectionCriterion.  Potentially just overriding the getCurrentValues
and getCriteriaItems methods.

See source code for more info:

For the definition of ATSelectionCriterion:
ATContentTypes/criteria/selection.py

For example of overriding ATSelectionCriterion:
ATContentTypes/criteria/portal_type.py

Good luck with this,

Tessa

Thanks for the pointer, I also got how AT gets values from it's default
views from looking at code examples.

Thinking about it more, it looks like creating custom list views based
on the existing code would probably be best.
