Rails - Dec 2005 - Adding model attribute without db field

I need to add an attribute to a model but there is no need to add a 
corresponding database field. The model is a child of ActiveRecord and 
it corresponds to a table in my DB but when I add it in the usual Ruby 
way, I get a ''number of redirects exceeded'' error.

Here is my code;

The model;

   class Category < ActiveRecord::Base
     attr :status
   end

The controlller;

    if params[:id] then @category = Category.find(params[:id])
    else @category = Category.find_by_default_category(''1'')
    end
    @category.status = 1

The view (just to access it)

<%  for category in @categories %>
<%= category.status %>
etc...

So, is there a way to add an attribute to an existing table based model?

Posted via http://www.ruby-forum.com/.

class Category < ActiveRecord::Base
  attr_accessor :status
end

should do the trick

or you could do it longhand

def status
  @status
end

def status=(val)
  @status = val
end
