django <=> rails mapping?

[braver]

I'd like to use the same database with django and rails, and perl's
Class::DBI, for that matter, to compare what they can do for me.
Naming conventions are different, so you'd have to supply explicit
table names in either one or another.  For now I generate SQL from a
django model and then issue set_table_name statements in rails, or use
names prefixed with model_ in rails.  Other ideas?
