Can't store object in session

Rails
1

Hello,

I got a session problem that I can’t solve.

session[:test] = “test session” works fine and can be printed from the
view.

session[:test] = User.find(1) returns true but the session is empty in
the view!
@data={:test=>#}, …

Session config:
config.action_controller.session = {
:session_key => ‘_www_session’,
:secret => ‘key removed…’
}

config.action_controller.session_store = :active_record_store

I found a thread on the RoR wiki that I should put model :user in
application.rb but that gives me an error. (depricated?)

Best regards.

You’re better off storing the id in the session, and reloading from
that. I don’t think that session supports saving entire objects
without serializing / deserializing them. I’ve actually never tried to
do this, because it’s a bad practic e (IMHO).

Hey Julian,

Could you show me how I only store the id? That’s actually what I am
trying to do :slight_smile:

This only fech the id, but does not work :confused:
@user_id = find(:first, :select => [“id”], :conditions => [“login = ?
and password = ?”, login, Digest::SHA1.hexdigest(password)])

Checked the log and the query is correct and only return ex. 1

Best regards.

The default to_s for an active record object looks like #<User: … >
which most browsers render as just #. If in your view you put <%= h
session[:test] %> you’d probably see what you were expecting
As Julian said putting whole model objects in the session isn’t a
great idea. If @user was your user you’d just stick @user.id in the
session.

Okay. Thanks. I got that working now :slight_smile:

How do I access an object from the view loaded by an application.rb
before_filter?

class ApplicationController < ActionController::Base

before_filter :user

def user
if session[:user]
@user = User.find(session[:user])
end
end

end

@user is working fine from my controllers but not in my views :confused:

Best regards.

Yeah, that won’t work.

You have no model on your find command. That makes no sense to rails
(active record, here).

Say I have a users table, and a User model.

@user_id = User.find(:first).id

or

user = User.find(:first)
@user_id = user.id

Either of those will find you the id.

ActiveRecord::Base.find will find a row, and create an object out of
it, so you need to ask the object what it’s ID is by sending it the id
message, as above.
