grails - Bidirectional One-To-One -

i have 2 domain classes:

class contract { string refno } class attachment { byte[] info string mimetype string filename }

how can set relationships have both contractinstance.attachment , attachmentinstance.contract? think bidirectional one-to-one i'm not sure (one contract has have 1 attachment)...

class contract { attachment attachment } class attachment { static belongsto = [contract: contract] }

this define 1-to-1 relationship between two, contract beingness owner of relationship. means if save/delete contract save/delete cascade attachment, inverse not true.

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
