Comment (by wolever):
As a warning: the “obvious” work around for this is to have custom ID
fields “pretend” to be auto fields by doing something like this:
{{{
def contribute_to_class(...): # XXX BAD XXX
cls._meta.has_auto_field = True
ls._meta.auto_field = self
}}}
However, this doesn't quite work either, because line 525 of
`/Users/wolever/Verso/Repos/web/env/massuni-web/lib/python2.6/site-
packages/django/db/models/base.py` in `save_base`(`update_pk =
bool(meta.has_auto_field and not pk_set)`), sets the `update_pk` flag,
which essentially causes:
{{{
if update_pk:
instance.id = get_last_inserted_id()
}}}
And, at least with the SQLite backend, the result of
`get_last_inserted_id` is the row number (or similar), *not* the value of
the `id` field.
So, in short, this issue can't be hacked around by setting
`has_auto_field`.
