Can't dynamically create an Acitve::Record object

I’m not sure what’s wrong with the code you listed, but here’s a module I use to create dynamic active record objects.

module Stone module Dynamic class << self def klass(table_name)

    tname = class_name_from_table(table_name)
    #see if it has already been defined
    const_missing(tname)
  rescue NameError
    define_klass(table_name)
  end

  def objeck(table_name)

    klass(table_name).new
  end

  private
    def class_name_from_table(table_name)
      Inflector.camelize(table_name)
    end

    def define_klass(table_name)

      tname = class_name_from_table(table_name)
      class_def = <<-end_eval
        class #{tname} < ActiveRecord::Base
          set_table_name('#{table_name}')
        end
      end_eval

      eval(class_def, TOPLEVEL_BINDING)
      const_get(tname)
    end
end

end end

Hope this is of some use, andy
