Subject: Re: Defining an ActiveRecord class within a method of another class

Sorry , I pasted the same thing twice

 irb(main):042:0> class Res
 irb(main):043:1>   def self.get(cls)
 irb(main):044:2>     eval("class #{cls};end")
 irb(main):045:2>     return eval("#{cls}.new")
 irb(main):046:2>   end
 irb(main):047:1> end
 => nil
 irb(main):048:0> x = Res.get("G")
 => #<Res::G:0xb7c05d5c>
 irb(main):049:0> x.class
 => Res::G
