Therefore it does not have an id. If you check subjekt.osoba_id, you will see it does not exist. It is subjekt.osoba_id that is stored in the table and it not existing it what leads to the error on save. (The value will not be pulled from subjekt.osoba.id on save() of subjekt, it is only set when osoba is assigned to subjekt.) You should save() the osoba instance before creating the related subjekt instance.
