Rails introduced smart integer columns in 2.1 which more or less translates to the number of bytes needed for storage. Here’s a little map taken from the adapter code. Do be careful, however, as some versions of Rails (2.1) break foreign keys. [...] [...] :limit determines the numeric type.

I hadn't realized that the fix could be implemented in my app's code, rather than rails itself ! Thanks once again, Nigel Thanks for your kind help, I will give that a go. I hadn’t realized that the fix could be implemented in my app’s code, rather than rails itself !
Thanks once again,

It seems to be the cleanest and most modular. Furthermore, when the app is upgraded to 2.2, I simply need to remove that file. The patch directly to the source that I included at the end requires the least amount of code, but it would probably require you to fork that version of rails and maintain it (because you'll need that version of rails on any box that will be used to develop/test/run in production), which seems like overkill. -John Hey Nigel,

Unfortuneately I'm stuck with Rails 2.1. When I specify foreign keys as :integer, they're ending up as BIGINT(11) in MySQL, resulting in failure to save my models. Thanks for any help you can give ! Cheers, Nigel Hi John,
