I have the following validator: @sa_orm.validates('variant_names', include_removes=True) def validate_unique_identifying(self, key, name_dict, is_remove): if is_remove: raise ValueError("DOn't") else: if name_dict.is_primary_identifying_flag is None: name_dict.is_primary_identifying_flag = False return name_dict
When deleting, I get the raised ValueError, but the deletion occured anyway. Is this the expected behaviour? Or there is some other settings that can prevent the deletion? -- SQLAlchemy - The Python SQL Toolkit and Object Relational Mapper http://www.sqlalchemy.org/ To post example code, please provide an MCVE: Minimal, Complete, and Verifiable Example.
