Are you sure this is syntactically correct. > db.table1.registry_id.requires = > IS_NULL_OR(IS_IN_DB(db,'ref_registry.registry_id',db.ref_registry._format))
In my table definitions I have: db.company.branch.requires=IS_NULL_OR(IS_IN_DB(db,db.branch.id,'% (name)s',zero=None)) ... which works. The syntax you're using doesn't look familiar to me. Kind regards, Annet.
