...hat relation does this foreign key belong to" etc... So what I am about to go and write myself is a database introspector that will look at a database and create all the Models for every table for me, including all the set_primary_key, all the has_many belong_tos, and many, if not all, of the validates_blah based on the database constraints. This is going to be quite an undertaking, so before I go and do it, does anyone know of something that already does this that has been previously written?
