Subject: Re: %r regex matching is ignoring my leading zeros

First of all, thanks guys for trying to help.

I changed my model validation to remove the brackets from around the \d. 
Still no dice.

When I tried it irb as Gabriele did it worked fine though.  Just doesn't 
want to work on the actual form I'm using.

I'm afraid I dno't know how to test rails as you have here:
>

> $cat app\models\foo.rb
> class Foo < ActiveRecord::Base
>   validates_format_of :bar, :with=>%r{^\d{4}$}
> end
> 
>  >> f=Foo.new
> => #<Foo:0x39658e8 @new_record=true, @attributes={"bar"=>""}>
>  >> f.bar ="0123"
> => "0123"
>  >> f.save
> => true
>  >> f.bar ="012"
> => "012"
>  >> f.save
> => false

I'm hosted on Dreamhost so they're on version 1.8.2 of ruby.

Maybe it does have something to do with conversion to a string.  Maybe 
I'll try and manipulate it in my controller before saving.

Any other suggestions?
