Merc,

You could add a method to Channel that looks like:
class Channel
  def self.standard_create(params, controller)
    ret = Channel.new params
    if ret.save
     controller.flash[:notice] = 'Channel was saved'
     controller.redirect_to :action => 'index'
    else
      controller.render :action => 'new'
    end
    return ret
  end
end

No need for metaprogramming in this case, just a simple method.

Thanks,

David
