Perhaps I misunderstand your question, but AFAIK vocabulary support this
scenario. In my application, I also have a country drop-down that is in my
case filled from a relational database. The vocabulary looks like this:
def landVocabulary(obj):
"""Get ktoids and ktonrs from session"""
session = zalchemy.getSession()
laender = session.query(Land)
laender_terms = []
for n, land in enumerate(laender):
laender_terms.append(vocabulary.SimpleVocabulary.\
createTerm(land.landid,
n,
land.name))
return vocabulary.SimpleVocabulary(laender_terms)
# Make function a vocabulary factory
alsoProvides(landVocabulary, IVocabularyFactory)
and in my configuration:
<utility
component=".utils.landVocabulary"
name="landVocabulary"
/>
Now I can use this vocabulary from any interface.
Best regards,
Hermann
