sqlalchemy.exc.InvalidRequestError: Class does not have a mapped column named

[hello-josh]

I am getting the following error on startup while trying to launch via sandmanctl mysql://root@localhost/instanthunt

sqlalchemy.exc.InvalidRequestError: Class <class 'flask_sqlalchemy.user_submission_vote'> does not have a mapped column named 'submitter_idclue_id'

I think it is having trouble handling a composite foreign key? Or is it because the field names do not match on both tables? This table's submitter_id maps to the foreign table's user_id

CREATE TABLE `user_submission_vote` (
  `user_id` int(11) NOT NULL,
  `submitter_id` int(11) NOT NULL COMMENT 'fk to user_submission.user_id',
  `clue_id` int(11) NOT NULL,
  `vote` tinyint(1) NOT NULL,
  `created` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
  `updated` timestamp NULL DEFAULT NULL,
  PRIMARY KEY (`user_id`,`submitter_id`,`clue_id`),
  KEY `fk_user_vote_user_submission_id` (`submitter_id`,`clue_id`),
  CONSTRAINT `fk_user_vote_user_id` FOREIGN KEY (`user_id`) REFERENCES `user` (`id`) ON DELETE CASCADE ON UPDATE CASCADE,
  CONSTRAINT `fk_user_vote_user_submission_id` FOREIGN KEY (`submitter_id`, `clue_id`) REFERENCES `user_submission` (`user_id`, `clue_id`) ON DELETE CASCADE ON UPDATE CASCADE
) ENGINE=InnoDB DEFAULT CHARSET=utf8

Here is the other table for completeness

CREATE TABLE `user_submission` (
  `user_id` int(11) NOT NULL,
  `clue_id` int(11) NOT NULL,
  `storage_uri` varchar(255) NOT NULL COMMENT 'Public URI to find the jpeg image in storage',
  `lat` decimal(10,6) DEFAULT NULL,
  `lng` decimal(10,6) DEFAULT NULL,
  `created` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
  `updated` timestamp NULL DEFAULT NULL,
  PRIMARY KEY (`user_id`,`clue_id`),
  KEY `fk_user_submission_clue_id` (`clue_id`),
  CONSTRAINT `fk_user_submission_clue_id` FOREIGN KEY (`clue_id`) REFERENCES `clue` (`id`) ON DELETE CASCADE ON UPDATE CASCADE,
  CONSTRAINT `fk_user_submission_user_id` FOREIGN KEY (`user_id`) REFERENCES `user` (`id`) ON DELETE CASCADE ON UPDATE CASCADE
) ENGINE=InnoDB DEFAULT CHARSET=utf8

I have a Spring+Hibernate app using these relations right now so I'm pretty sure the table definitions aren't an issue.

Could you past the full error traceback? Not sure where it's even getting the name submitter_idclue_id from...
