id is added automatically to every model by OpenERP.

Every database requires a unique identified and OpenERP manages this via the id field and a related sequence.

The others are created for every model where self._log_access is set to True (which it is by default).

They are required if access rules are to be implemented for the model.

  • the user who created the record (create_uid)
  • the time it was created (create_date)
  • the user who last updated the record (write_uid)
  • the time it was last updated (write_date)

If a value for self._log_access is not specified, then you can prevent them from being created if self._auto is set to False
