The right approach (if it's really a convention for rails code) would be
to call
(add-hook 'write-file-hooks 'untabify-before-write nil t)
inside the `rails-mode' function. The last parameter to `add-hook'
makes this hook buffer-local, so the untabify function would only be run
when saving a file that is in rails-mode.

I think you (or F. Unglaub) should send a bug report to the rails-mode
devs. Modes must not change global settings.

Yes, that's a workaround.
