Earlier this year, I had a discussion with Rails Core and they
suggested I make a pull request. I did:
https://rails.lighthouseapp.com/projects/8994/tickets/4347-add-foreign-key-support-to-migrations-and-schemarb-dump
I did not receive any feedback on my original request, so I went on
maintaining github.com/matthuhiggins/foreigner. I would happy to make
an update to the patch, if it will be considered by the Core team.
While it is fruitless to debate the value of foreign keys to opponents
and proponents, it should be noted that the update I offered has zero
effect on those not using foreign keys. It's also worth suggesting
that the initial version can start with no cascading options, so that
all application logic is kept in the application, and the foreign keys
act as a neutral constraint similar to NOT NULL.
I don't think this is right. A foreign key could be null. If you don't
want it to be null you should be explicit about it.
By the way, thanks for the foreigner gem.
