Hi JP,
I've been using your multiple-db-support for sometime now and i wondered if
you are still actively developing it? I have a couple of suggestions/queries
to do with a few of my specific needs and I would guess those of others...
There are a couple of tickets about this on trac, but I might try and do
some bits independently so I wanted to ask for your feedback...
- I'd really like if I could define a FK relationship that spans
databases, at present that will work but the backwards relationship is
broken and it throws a validation error.
- I'd like this 'spanning foreignkey' to not break the django ORM... so
that Model.objects.filter(fk_class__column='whatever') would still work.
I'm guessing that this would be quite a lot of work... Probably consisting
of:
- A new type (or types) of Field, perhaps OtherDBForeignKey or something
- A new type of descriptor for each of these new field types
- Some new logic in django.db.models.query to catch the case of a db
spanning relationship and split the queries up
- Finally some way to build the sql so that it looks like SELECT
[columns,] from first_table where pk in (list_of_pk_values); the list will
be generated from a separate query as a result of splitting the queries up
in the last step.
What do you think about the amount of work that would be needed to get all
this working?
As an aside i have a copy of multiple-db-support that I've merged with trunk
as of rev 5371, it might be good to get this checked into django so other
people can work on it, if there's still any interest...
Thanks in advance,
Ben
