Hi all, I am trying to model the following situation:
I have an entity (a committee), which is stored in a single table. Mapping Committee object to this is trivial. Defined in this table is a foreign key (type) which references the pk of a table committee_type. I wish to map Committee obj to the join between tbl_committee and tbl_committee_type, something possible using join I think. However, I also want to enforce the constraint that any type added to a new committee object must be present in tbl_committee_type. I do not wish to be able to add a type and have that added to the table by sqlalchemy. For example, if type "audit" already exists as the pk in tbl_committee_type and I try to set type to "remun" on a new Committee object and flush, I want it to fail. I imagine this isn't too difficult, but at this stage, I cannot figure out how to do it. Any help would be gratefully appreciated.
