Re: Bug: Manually changing "_meta.db_table" for model causes "missing FROM-clause entry for table" error

I don't think that sould be possible to change real table name "on the fly". If I'm not mistaken, that kind of attribute is used by model's meta class during class creation process to populate the django model cache, which in turn only occurs during the django configuration step. 2017-07-13 14:08

Re: Use one correspondig database user for each application user
