Problem with User Login from Agile Web Development

Rails
#1

I am trying to use an expanded version of the User Login from the Agile
Web D. with Rails book. It takes the user name and password
but then says “Invalid user/password combination”. Looking at the log
everything seems to be fine until it sends the query to MySQL. The
query shows that the name is ‘’ instead of the name that was passed to
the self.login method.
I checked the code multiple times and even downloaded the files as the
book had an error in another part of the model but can’t find the
problem.

The code in the model is:
def self.login(user_name, password)
hashed_password = hash_password(password || “”)
find(:first,
:conditions => [“user_name = ? and hashed_password = ?”,
user_name, hashed_password])
end

Log in if the name and password (after hashing) match the database,

or if the name matches an entry in the database with no password

def try_to_login
User.login(self.user_name, self.password)
end

And what’s in the form itself?

Do you mean what data is associated with the user_name and password
variables? user_name is set to the administrator login and the password
is their password.
The following shows the log for a failed entry (names changed):
