I'm trying to make a game (or at least something, so I can learn) with
Ruby CGI. I'm having a really hard time with sessions. I have some
variables that I want to save, but they are not strings. They are
classes that I have defined. Is there any way to save them with a
session without them just being converted to strings and then being read
back in as strings when I load the session up? Here's what I have:
#! /usr/bin/env ruby
require "cgi"
require "cgi/session"
require "setdeck"
require "set"
require "setcollection"
require "setboard"
cgi = CGI.new("html4")
sess = CGI::Session.new( cgi, "session_key" => "crappyset",
"session_id" => "1234", #cgi.remote_addr,
"prefix" => "setgame.",
"tmpdir" => "/tmp")
if sess["deck"].nil?
deck = SetDeck.new
sets = SetCollection.new
board = SetBoard.new(12)
deck.shuffle!
else
deck = sess["deck"]
sets = sess["sets"]
board = sess["board"]
end
board.place(deck.dealn(board.holes.size))
if cgi.has_key?('selections')
tomark = cgi['selections'][0].split(',').collect { |x| x.to_i }
tomark.each do |marked|
board.select(marked)
end
end
sess["deck"] = deck
sess["sets"] = sets
sess["board"] = board
sess.update
cgi.out{
cgi.html {
cgi.head {"\n" + cgi.title {"What a crappy implementation of set!"}}
+
cgi.body {"\n" + cgi.pre{board.to_s} +
cgi.br +
cgi.form {
cgi.textarea("selections") +
cgi.br +
cgi.submit("Check them!")
}
}
}
}
I am just getting started with this, but I'm trying to learn how
sessions work and having a hell of a time. I need to make sure that
when deck, sets, and board are loaded up, they are loaded as a SetDeck,
a SetCollection, and a SetBoard, respectively. Is there any way to do
this without using Marshal? And if I need to use Marshal, how would I
do that with sessions?
