Option :case_sensitive for validates_exclusion_of

#1511

Wherever you look, the example for uses of validates_exclusion_of is to reserve usernames. I recently found out that validates_exclusion_of is case sensitive: Why, however, would I want to exclude "admin" if users can still sign up as "Admin"?

I've developed on a patch that introduces a :case_sensitive option to validates_exclusion_of -- so that I am not forced to using validates_each just because I want to prevent users to sign up as "admin" in upper or lower case.

I will also push the patch to github.com/awendt/rails

    Please bear with me, I noticed I've attached the reverse patch. Here is the correct one.

    You should just use validates_format_of and a regular expression.

    Thanks.

    I think that a case sensitive option make sense also.

    But it should be also included in validate_inclusion_of. Maybe post this in the Rails group and try to get a couple more +1.
