For instance : add_foreign_key(from_table, to_table, options) remove_foreign_key(from_table, options) foreign_keys(table_name) I really like to keep my development computer to run as fast as possible (ie without a database service), so I have even tried to integrate this plugin into OVirt, in a transparent way for exist...

Is there any reason why AR has never supported foreign-key constraints? I can understand the lack of support for triggers and stored procedures since they are highly dependent on the database to create a wrap API around them. But this is not the case for foreign keys. This is specially important for open-source projects like Redmine/Chiliproject and Gitorious where you shouldn''t be
