[Zope] submitting multi-checkbox

[Norman Lorrain]

I'm trying to submit multi-checkbox (Formulator widget) values to a
database using ZSQL.

My  database schema defines the fields as boolean; Formulator converts
the values to a list of checked items, e.g. ['checked_item_one',
'checked_item_two'].  Only checked items are added to the list.

How can I map the formulator output to proper SQL? (a list of booleans)
I have a couple of ideas, but I'm new to Zope and not sure what would be
best, or even possible.


Thanks
