Rails - Jun 2006 - how can i redirect a person after a login

i built my own login system, but unfortunately, i am having problems 
(ie, can''t really figure out how) to redirect a person back to the page
he was requesting before logging in...say, as the admin i want to edit a 
certain message/logo, whatever, so i click on it, and i get redirected 
to my login page. after the admin logs in, he gets redirected to the 
homepage - i couldn''t figure out how to redirect to the page he 
requested...
my loggin system is this:


APPLICATION CONTROLLER:

def secure
redirect_to :controller => ''login''  unless @session[:admin]
== 1
end
-------------------
in my LOGIN CONTROLLER:

def authenticate
 pswd  = [ ''shai'', ''octava'']
 @input = [  "#{params[:user][:name]}",
"#{params[:user][:password]}"  ]
       if pswd == @input
           @session[:admin] = 1
      	   flash[:notice] = ''successful entry.''
	   redirect_to :controller => ''messages''  ####THIS IS WHAT
I NEED TO
FIX
        else
	   @session[:admin] = 0
      	   flash[:notice] = ''?????? ??????, ??? ??? ????.''
	   redirect_to :action => ''login''
        end
end
-------------------

(i put the secure method in any action i wish to protect, and walla!, 
everythings good)(except the redirecting issue)
i know the answer should be something like @session[:url_path] = xyz, 
and then redirect in the authenticate action to @session[:url_path], but 
the problem is, i''m not really sure what the xyz part is (that stores 
the current url the person is on) and i aint really sure what the 
correct syntax for doing this is...

if anyone has an answer, clue, or just plain sympathy, i''ll be ready; 
thanks.
hola,

redirect_back_or_default is probably what you want. check 
acts_as_authenticated for a use case. it only seems to actualy redirect 
back when your access to a page was ''interrupted'' for needing
login, say
youre on a page that normal users can only view, and special users can 
additioanlly delete or add items, if you click on a link to 
/account/login youll never come back to that page after logging in, 
unless im missing something..

-========detailed=========-

this is the way the admin is redirected:

---------
def secure
redirect_to :controller => ''login''  unless @session[:admin]
== 1
end
---------

and then i implement the secure method in any one of the actions i want 
to protect, such as ''edit'':

def edit
secure
...
end

and then, when a person who is on the page 
http://localhost:3000/messages wants to edit a message, say 
http://localhost:3000/edit/3, he will automaticly be redirected to 
http://localhost:3000/login/login, where in this action there will be a 
user, and pswd field, and if he enters them correctly (which you can see 
in the authenticate action, is ''shai'' and
''octava'') he will be
redirected to :controller => ''messages'' (above where i
wrote ''#WHERE I
NEED TO FIX''). this is the place i need to somehow, (if possible??), 
insert some kind of a parameter/variable that will give me the 
path/url/action-conroller/whatever of the last page visited before the 
''redirection'' to the login page = = = i.e, after entering the
user+pswd,
get redirected back to (examply obviously) http://localhost:3000/edit/3.

is there any way to do this??
(ps thanks for the reply)

I think a better to do is with before_filter call back function.

for example

def secure
   redirect_to :controller => ''login''  unless
@session[:admin] == 1
end

Then in your edit controller

class EditController < ApplicationController
  before_filter :secure, :except => :login  #except is a method that 
doesn''t require login (you can put more in the except)
  ........

Hope this helps  :)
