AuditLog error when cloning objects

[raayu83]

I'm trying to clone objects including their m2m fields using a solution I found on StackOverflow.

Unfortunately I get the following error:
null value in column "object_pk" of relation "auditlog_logentry" violates not-null constraint

I assume this is because the cloned objects pk field has to be set to None in order for it to be assigned with a new ID automatically.

Is there any way to work around this?

You can get around this by manually assigning an id to the copied object but be very careful it's not an ID already in use, or you'll overwrite something else. You could also probably temporarily unregister the model with AuditLog, which disables the signals.

Since these seemed more like hacks than an actual solution I switched to django-simple-history which suits my usecase better

Not yet! Unfortunately, I don't have time to work on it. It would be great if you can work on the issue and prepare a fix

Hello again, i finally did fix the problem, you will find bellow an example how I handled it in my project :

baseobj = ObjectModel.objects.get(pk=12)
obj = baseobj
obj.pk = None 
obj.save()

instead of following the previous method, i do it otherwise now :

baseobj = ObjectModel.objects.get(pk=12)
obj = ObjectModel()
for field in baseobj._meta.fields:
                                if field.name != 'id':  
                                    setattr(obj, field.name, getattr(baseobj, field.name))

Hope it helps
