Maybe the core could make a request? Peter
---------- Forwarded message ---------- From: Bob Silva <[EMAIL PROTECTED]> Date: Jan 23, 2006 7:34 PM Subject: RE: [Rails] Re: validates_numericality_of positive integer To: [EMAIL PROTECTED] I hacked together a plugin to add a few parameters to validates_numericality_of based on your needs and my laziness for explicit checks. >From the README: Adds the following parameters: (plus the messages generated as an error) :gt => ## "must be greater than ##" :gte => ## "must be greater than or equal to ##" :eq => ## "must be equal to ##" :lt => ## "must be less than ##" :lte => ## "must be less than or equal to ##" :odd => ## "must be an odd number" :even => ## "must be an even number" :within => ##..## "must be within ## and ##" Usage: (in your case) validates_numericality_of :foo, :integer_only => true, :gt => 0 validates_numericality_of :age, :integer_only => true, :within => 13..100 If RoR team would like to integrate into Rails, have at it. I don't do well with rejection, so I won't offer it as a patch unless requested. Download it at: http://www.umesd.com/better_validates_numericality_of.zip I'll get it downloadable via script/plugin in due time. Gotta write a few unit tests first.
