Re: save() prohibited to prevent data loss due to unsaved related object 'committee'
The Committee.save() is: def save(self, *args, **kwargs): if not self.slug: self.slug = 'committee-%s' % self.id And yes, after removing that save function everything works fine.

Re: save() prohibited to prevent data loss due to unsaved related object 'committee'
I've found out that this error is happening because I also have a def save() function on the committee model. So I am not sure if this is a bug or I am not suppose to have it like that.

save() prohibited to prevent data loss due to unsaved related object 'committee'
Hi, I am getting this error when running model post save signal. The error traceback is for gr.save() it seems like the committee model is not saving before it need to be assigned to GroupRole model as a FK. this is the post_save signal code. @receiver(post_save, sender=Community) def set_default_reasons(sender, instance, created, dispatch_uid='set_default_reasons', **kwargs): if created: committee = Committee(community=instance, name='Board', slug='main') committee.save() for group_role in settings.DEFAULT_GROUP_ROLES: gr = GroupRole(committee=committee, role=instance.roles.get(title=group_role), group=instance.groups.get(title=group_role)) gr.save() Thanks. -- You received this message because you are subscribed to the Google Groups "Django users" group.
