Hi All... Apologies in advance if this isn't the right
group (but I
couldn't find a rails specific one) anyway -
I think I am having a problem passing data around in my
MVC.
I have a view that looks has this in the middle:
<code>
<%= form_tag :controller =>
"login", :action =>
"login" %>
<tr>
<td>DOMAIN\Username:</td>
<td><%=
text_field(:login, :username)
%></td>
</tr>
<tr>
<td>Password:</td>
<td><%=
password_field(:login, :password)
%></td>
</tr>
<tr align = "left">
<td /><td><input
type="submit"
value="Submit"></td>
</tr>
<%= end_form_tag %>
</code>
and here is my login_controller.rb
<code>
class LoginController < ApplicationController
before_filter :authorize, :except => [:login, :logout]
def login
if request.get?
session[:username] = nil
else
#get the username and password from the array
username = params[:login][:username]
password = params[:login][:password]
# Split username on domain and alias
split_username = params[:user][:name].split('\\',2)
if split_username.length != 2
flash[:notice] = "You did not enter a properly
formatted domain
and username"
redirect_to :action => 'login'
else
# Authenticate username and password
domain = split_username[0]
username = split_username[1]
password = params[:user][:password]
if authenticate domain, username, password
# User has been authenticated
session[:username] = username
else
flash[:notice] = "Incorrect username or
password"
redirect_to :action => 'login'
end
end
end
end
def logout
session[:username] = nil
end
require 'dl/win32'
LOGON32_LOGON_NETWORK = 3
LOGON32_PROVIDER_DEFAULT = 0
BOOL_SUCCESS = 1
AdvApi32 = DL.dlopen("advapi32")
Kernel32 = DL.dlopen("kernel32")
def authorize
redirect_to( :controller => 'login', :action =>
'login' ) unless
logged_in?
end
def logged_in?
session[:username] != nil
end
def authenticate(domain, username, password)
# Load the DLL functions
logon_user = AdvApi32['LogonUser', 'ISSSIIp']
close_handle = Kernel32['CloseHandle', 'IL']
# Normalize username and domain
username = username.strip.downcase
domain = domain.strip.downcase
# Authenticate user
ptoken = "\0" * 4
r,rs = logon_user.call(username, domain, password,
LOGON32_LOGON_NETWORK, LOGON32_PROVIDER_DEFAULT, ptoken)
success = (r == BOOL_SUCCESS)
# Close impersonation token
token = ptoken.unpack('L')[0]
close_handle.call(token)
session[:username] = username
return success
end
end
</code>
At the top of my application.rb I have:
<code>
class ApplicationController < ActionController::Base
protected
def authorize
#changed from cookie to session
unless session[:username]
 session[:return_to] = request.request_uri
redirect_to :controller => "login"
return false
end
end
end
</code>
So the filtering works fine, when I try to access a
protected page, it
goes to my login.rhtml.
but when I login, It craps out on me with this:
<code>
NoMethodError in LoginController#login
You have a nil object when you didn't expect it!
You might have expected an instance of Array.
The error occured while evaluating nil.[]

I swear I think everything is correct, but it isn't
working. I don't
have any rails guru's around, so I thought that I'd risk
getting
roasted and post it here.
