---------------
! SQLObject requires that you use an integer primary key, usually
! defined in a specific way (``INT PRIMARY KEY AUTO_INCREMENT`` for
! MySQL, for instance, or ``SERIAL PRIMARY KEY`` for PostgreSQL). You
! cannot use strings or other kinds of values.
! This restriction will probably be removed soon.

---------------
! Yes, you can use non-integer IDs, but only in CVS_ now.
! .. _CVS: http://sqlobject.org/#anonymous-cvs
!
! If you use non-integer IDs, you will not be able to use automatic
! ``CREATE TABLE`` generation (i.e., ``createTable``). You also will
! have to give your own ID values when creating an object, like::
!
! color = Something.new(id="blue", r=0, b=100, g=0)
!
! IDs are, and always will in future versions, be considered immutable.
! Right now that is not enforced; you can assign to the ``id``
! attribute. But if you do you'll just mess everything up. This will
! probably be taken away sometime to avoid possibly confusing bugs
! (actually, assigning to ``id`` is almost certain to cause confusing
! bugs).
!
! If you are concerned about enforcing the type of IDs (which can be a
! problem even with integer IDs) you may want to do this::
!
! def Color(SQLObject):
! def _init(self, id, connection=None):
! id = str(id)
! SQLObject._init(self, id, connection)
!
! Instead of ``str()`` you may use ``int()`` or whatever else you want.
! This will be resolved in a future version when ID column types can be
! declared like other columns.
