This is what I have done in the past, but it may not be the best solution.
In your user model....

class User < ActiveRecord::Base

  def beautifunction
    {  :pizza => ''salame'' }
  end

  def self.human_attribute_name(s)
    beautifunction[s.to_sym] || super(s)
  end

end

Best regards.

Re: How to alias the columns names to change the name on error_messages_for ?

one correction to my solution:

use self.beautifunction (should be a class method not an instance method)

Re: How to alias the columns names to change the name on error_messages_for ?

That''s a good question.  As far as I can tell, there is no Rails way to
do
this as of Rails 2.0.2.  I spent some time reviewing how error_messages_for
works and then came up with this solution.  I would love to know if 2.1
addresses the problem, or if we''re really looking at a documentation
problem.

Anna Lissa

I use the Human Attribute Override plugin (http://
agilewebdevelopment.com/plugins/human_attribute_override) with Rails
2.0 which essentially does the same thing as your earlier example.

Just committed this month is a patch (http://rails.lighthouseapp.com/
projects/8994/tickets/535-humanize-inflections) that allows you to
specify particular results for the humanize string method. I think
it''s a flawed approach because it is not unreasonable to have the same
attribute name on different models but to want different display names
and I as far as I can see it will not allow that.

Best regards,
Andrew
