Well, I added a couple of print debugs to map\_first\_post ``` def map_first_post(row) puts "Mapping parent #{row['msg_id']} #{row['subject'][0..40]}" mapped = map_post(row) mapped[:category] = category_id_from_imported_category_id(row['category']) mapped[:title] = row['subject'].strip[0...255] mapped puts "Mapped message #{row['msg_id']} #{row['subject'][0..40]}" end def map_reply(row) parent = @lookup.topic_lookup_from_imported_post_id(row['in_reply_to']) if parent.blank? puts "Parent message #{row['in_reply_to']} doesn't exist. Skipping #{row['msg_id']}: #{row['subject'][0..40]}" return nil end mapped = map_post(row) mapped[:topic_id] = parent[:topic_id] mapped end ``` These print ok and suggest the parent is mapped (imported?) 873 / 65936 ( 1.3%) [3895 items/min] Mapping parent 9205270657.AB03850@ben.dciem.dnd.ca A CALL FOR HELP Mapped message 9205270657.AB03850@ben.dciem.dnd.ca A CALL FOR HELP 874 / 65936 ( 1.3%) [3900 items/min] Parent message 9205270657.AB03850@ben.dciem.dnd.ca doesn’t exist. Skipping 9206031720.AA22567@ben.dciem.dnd.ca: A CALL FOR HELP So, don’t see why the parent is blank in map\_reply. The only thing I note is that the numbers (873/874) are one less than rowid above. But I don’t think I can go much further as I don’t know what @lookup.topic\_lookup\_from\_imported\_post\_id is doing and it is very laborious to edit with vi and rerun the import, with each cycle taking around 30 minutes. --- _[View the full topic](https://meta.discourse.org/t/parent-message-doesnt-exist/141746)._
