Newbie problem => sessions

Rails

hi!!

i have a little problem, that i cant resolve.

how can i put in a session as an object? i mean, for example i know only
to give a value to a session so:

@session[‘something’] = “hello world”

but i want to give to the @session[‘something’] a name, an age, etc
so i can call the name of the session like:

@session[‘something’].name
or
@session[‘something’].age

i dont know which one the right syntax is.

thanks!! bye!

hey sabin,

@session[‘key’][‘value’] = 3
@session[‘key’][‘value2’] = 3.5
@session[‘key2’][‘someother-value’] = 4

this would result in the data you just entered like this:
(two seperate hashes)

‘key’ hash would look like this: {“value” => 3, “value2” => 3.5 }
and the
‘key2’ hash would look like this: {“someother-value” => 4 }

…if this isn’t helpful enough, i personally like rubycentral.com; it’s
a great site. either way, i hope on of the two provides a good enough
solution to the problem.
good luck,

i’m not exactly sure of what you are trying to do in the big picture, so
i may be leading you to places you don’t need to go to (?) , but here’s
a shot in the dark, i hope it somewhat helps.

if you want to assign values to a @session[x][y] variable, (creating a
hash) you will first need to define that the @session[x] is of a Hash
type.
so, to assign, say, 100 to @session[‘something’][‘vaue1’] you will first
need to define

@session[‘something’] = Hash.new

and then

@session[‘something’][‘value1’] = 100

…if you check the contents of the session
((@session[‘something’].inspect)) you will see that it will give you:

{‘value1’ => 100}

(btw, if you are using the acl system from wiki.rubyonrails.com, and you
don’t want to erase the @session[‘user’] - - you just want to add more
data, make sure you put the Hash.new BEFORE you the session is created.
(i.e, the user logs in)
so that Hash.new doesn’t overwrite the current session.
i hope this helps. i know there are great reading materials in
rubycentral.com if i’m leading you round round and astray.

Hi Sabin,

There’s no magic here. The session will hold an object if you assign an
object to it.

@session[‘something’] = “hello world”

But if you keep using ‘@session’ you’re going to have problems. The
instance variable syntax has been depracated since 1.2. Use ‘session[]’
instead (drop the ‘@’)

but i want to give to the @session[‘something’]
a name, an age, etc

You need to create a model for your ‘something’ object that includes
those
attributes. Then assign that object to the session. The syntax you
wanted
to use should work, but I haven’t tested it…
