Subject: Re: accessing session with session.each

well, I've finally solved the thing

I tried in the controller the following

class Session
  def sayHello
    "hello"
  end
end

and then, I saw the error saying something about
CGI::Session

In the C:\ruby\lib\ruby\1.8\cgi\session.rb file, the Session declaration 
wa inside the CGI class, so I had to

class CGI::Session
  def sayHello
    "hello"
  end
end

and it just worked

so I went on and defined

class CGI::Session
  def data
    unless @data
      @data = @dbman.restore
    end
    @data
  end
  def each(&block)
    data.each &block
  end
  def each_pair(&block)
    data.each_pair &block
  end
end

BTW, is there some way to redirect a bunch of methods (each, each_key, 
each_pair, each_value, empty?, to_a, etc... I guess you know what I 
mean) from self to self.data?

and then, to give it a try, in a view I added the following

<table border="1">
  <tr><th colspan="2">params</th></tr>
  <tr><th>key</th><th>value</th></tr>
<% session.each_pair { |key, value| %>
  <tr><th><%= h key %></th><th><%= h value %></th></tr>
<% } %>
</table>

Well, that's all

Saludos

Sas

PS: I'm pretty impressed with how easy is to extend ruby. Just imagine 
doing such a thing in asp...
