I’m getting some weird behavior in one of my models. I have a model  
defined something like this

class User \< ActiveRecord::Base  
attr\_accessor :password

validates\_presence\_of :password  
end

If I validate the model without specifying a password, I get [“can’t be  
blank”, “can’t be blank”] for :password instead of just one “cant’t be  
blank”. If I comment out the validates\_presence\_of statement, then no  
errors. So it doesn’t seem like it’s being defined elsewhere(though a  
plugin or some such). Any idea what might be going on here?

Thanks,  
Steve

When you call the page, do you use a request.post?

This can happen if the model file gets loaded twice. Do you have

require ‘user’

somewhere in your code?

Yes, I had a “load” statement in there that was causing this to happen.  
Thanks.
