Hi! Hi have a similar problem using table reflection a la sqlsoup. My DB Backend ist postgresql 8.3.
I have a many to many relation: orms5=# \d project_programming_language Table "public.project_programming_language" Column | Type | Modifiers -------------------------+---------+----------- project_id | integer | not null programming_language_id | integer | not null Indexes: "projprogpkconstraint" PRIMARY KEY, btree (project_id, programming_language_id) Foreign-key constraints: "programmierspracheconstraint" FOREIGN KEY (programming_language_id) REFERENCES programming_language(programming_language_id) ON DELETE CASCADE "projektconstraint" FOREIGN KEY (project_id) REFERENCES project(project_id) ON DELETE CASCADE I got the same message, when delete an object of the table programming_language: Dependency rule tried to blank-out primary key column As you can see, the foreign key constraints in the db work fine: I can drop the row via a DELETE statement in sql.
