I have several tables where there should only be one possible combination of
two uuid-fields per table (mostly many to many links).
I have created 'unique' constraints for those fields in Postgresql so the
database would not accept any inserts or edits which violates that
constraint.
I use that in combination with 'try:.. except:' to insert data.
Can DAL be used in a way for this? As far as I understand the IS_NOT_IN_DB
validators that it is working on form-level and not on database level and I
am not sure whether it can be used for a combination of fields (unless I do
it with a computed field - which will use up a lot of extra resources).
