Hello guys, I can't detect any pattern, maybe 1 in each 1000 thousands edit of a certain model returns an IntegrityError on a m2m field. Most of the times this field wasn't even modified. When a model is saved I believe django always wipes the m2m field and then readds the items, right? I saw django calls clear() and then add()s the items. My code then fails with:
IntegrityError: duplicate key value violates unique constraint "app_model_m2m_field_key" It seems like the add of items is performed before the items are cleared, which is very weird. I've tried to reproduce it but it's very hard, only happens occasionally. Any idea what could cause it? Could maybe setting auto commit solve this problem? Thanks in advance Cheers, Bernardo -- You received this message because you are subscribed to the Google Groups "Django users" group.
