How to change the type of a field?
...now how you'd convert a string (think currency like '1.23') to the integer 123? I assume you'd have to parse it as a float or decimal, multiply it by 100, then save it as an integer, but I can't find the right docs to do this. Thanks!

\Z allows to have \n at the end of the string, so "123\n" will pass validation, regardless that it's not fully numeric. But if you use \z then it will be more correct regexp: /\A\d+\z/
