Request

Parameters: {“name”=\>“paco”, “commit”=\>“Login”, “password”=\>“12345”}

Show session dump

* * *

:user\_id:  
flash: !map:ActionController::Flash::FlashHash {}

# Response Headers: {“cookie”=\>[], “Cache-Control”=\>“no-cache”}

very strange. attached is my model/user.rb file. I did another test,  
to try to use a wrong username, i got a response saying “Invalid user/  
password combination”

So, looks like the

def self.encrypted\_password(password, salt)  
string\_to\_hash = password + “wibble” + salt  
Digest::SHA1.hexdigest(string\_to\_hash)  
end

string\_to\_hash gives me error !

Please help or point me to the right direction to solve this  
issue…otherwise, i can not proceed with the rest of the  
chapters…

I am using Window XP and InstantRails to develop this application,  
using MYSQL.

your help is greatly appreciated !
