Are you saving the string representation of the model instance? I would cast the model instance as a str in that case, i.e. str(instance).
-----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Henrik Baran Sent: Sunday, November 12, 2017 6:54 AM To: [email protected] Subject: [1.11] deviation between .create() and .update() Hi Django users, I observed something weird while trying to update an existing database record. I create new records by passing a dictionary as **kwargs to .create(). This dictionary includes strings, integers and model instances matching with my model fields. However, one model field is a CharField that can be populated passing a model instance. This works fine for create. But if I try to update this record passing the exactly same dictionary as **kwargs to .update(), Django raises a TypeError telling me that I cannot update that field because it is a CharField and I cannot pass model instances. ... so is this a bug, because it works in .create() or must I adapt my approach? Thanks a lot for reply. BR, Henrik -- You received this message because you are subscribed to the Google Groups "Django users" group.
