Hello everyone,
I am just starting a project for school in RoR and I am a complete
n00b ^^
Here''s my problem :
I need to get the user''s login stored in the session but for some
reason I cannot.
Here''s my login method code :
def login
if request.post?
@user = User.find_by_username(params[:login])
if @user and @user.password_is? params[:password]
session[:user] = @user.id
redirect_to :controller => ''games''
else
@auth_error = ''Wrong username or password''
end
end
end
And here''s the code of my GamesController. User needs to be logged in
to access the games webpage (using check_auth method) and on that
page the user can create a new game (adding a record in the game
table,
with a few fields from the form filled by the user and a field with
the user''s
username, that''s why I need to get it from session[:user]).
before_filter :check_auth
def check_auth
unless session[:user]
flash[:error] = ''You need to be logged in to access this
panel''
redirect_to :controller => ''users'', :action =>
''login''
end
end
def create
@game = Game.new(params[:game])
@user = User.find(session[:user])
@game.host = @user.username
respond_to do |format|
if @game.save
format.html { redirect_to(@game) }
format.xml { render :xml => @game, :status
=> :created, :location => @game }
else
format.html { render :action => "new" }
format.xml { render :xml => @game.errors, :status
=> :unprocessable_entity }
end
end
end
Thank you very much in advance for any help you could give,
I really need to get this working to finish my project ^^

To understand how to require an user to log in to complete certain tasks, I would recomment you to read this excellent tutorial: http://www.railsforum.com/viewtopic.php?id=14216 Regards, Rey9999 On 30 Mag, 14:17, Blaede <n.naya...-AgBVmzD5pcezQB+pC5nmwQ@public.gmane.org> wrote:> Hello everyone, > > I am just starting a project for school in RoR and I am a complete > n00b ^^ > Here''s my problem : > > I need to get the user''s login stored in the session but for some > reason I cannot. > Here''s my login method code : > > def login > if request.post? > @user = User.find_by_username(params[:login]) > if @user and @user.password_is? params[:password] > session[:user] = @user.id > > redirect_to :controller => ''games'' > else > @auth_error = ''Wrong username or password'' > end > end > end > > And here''s the code of my GamesController.

Thank you very much for your answer Rey. I took a look at the tutorial and it seems very interesting indeed. However, my application is very simple, all pages are accessible by all, except one (the games page) accessible by logged users only. This feature works as it is on my website, my problem comes from the fact I have troubles extracting information from the session[:user]. I need to access the fields of the logged @user. My project must be finished by the 5th of June so if someone could help me solve this problem without re-designing my entire application, I''d be really gratefull.

Hi Blaede, Blaede wrote:> On one hand I have : session[:user] = @user.id > and on the other hand (in another controller) > I have : @user = User.find(session[:user]) > which if I am not mistaken should put in > @user the session''s user.It will put the object retrieved in your User.find into @user. Problem is the User.find is returning nil. So you need to figure out why that is. A three things come to mind right off the bat. 1) It could be that session[:user] is nil because @user.id is nil when you set session[:user]. Do a puts right before you set session[:user] to check the value of @user.id in the console, and do likewise afterwards to see the value of session[:user] 2) It could be that session[:user] is not an int, which is what User.find() expects. You can check that with session[:user].is_kind_of?(int) (check the syntax) or you can just force it with User.find(session[:user].to_int) 3) It could be that you''re invoking the controller/method that uses session[:user] before the one that sets it. Use puts to display the values as your app executes and you''ll figure out which it is, or what else it is if it''s not one of these.
