Hashed_Pasword?

jung · February 21, 2009, 9:25pm

I am having a problem with my hashed_password.
I am following the lessons in the apress beginning rails book.
Here is my issue:

def password_required?
hashed_password.blank? || !password.blank?
end

Ruby is calling this method out as a problem.

Error message from the web server:
undefined local variable or method `hashed_password’ for #<User id: nil,
login: “”, email: “”, hashed_passwd: nil>

I am stuck!

Is the variable named hashed_password or hashed_passwd?

Here is the entire section of code :
def self.authenticate(login, password)
user = find_by_login(login)
return user if user && user.authenticated?(password)
end

def authenticated?(password)
hashed_password == encrypt(password)
end

protected
def encrypt_new_password
return if password.blank?
self.hashed_password = encrypt(password)
end

def password_required?
hashed_password.blank? || !password.blank?
end

def encrypt(string)
Digest::SHA1.hexdigest(string)
end

It appears your model has a field called ‘hashed_passwd’, which is
not the same as ‘hashed_password’. So change one of 'em

end

def password_required?
hashed_password.blank? || !password.blank?
end

def encrypt(string)
Digest::SHA1.hexdigest(string)
end

The web server is calling out line 47 which is hashed_password.blank? ||
!password.blank?

I think the hashed_password.blank? is my problem but I do not know why.

the variable is hashed_password.

Um, shouldn’t you be storing the result of the hash into
hashed_password?
Also, if this is part of a User class (as suggested by the output
earlier) then you probably want to use @ -scoped variables, not
method-local.
def Klass
some_variable = value
end

is NOT the same as:
def Klass
def initialize
@some_variable = value
end
end

That seems the most likely problem to me. If this doesn’t solve your
problem, could you post the point at which you initialise/declare your
variables?

Cheers,
Michael

No, you should be aware that this is pretty obviously an ActiveRecord
model
object in a Rails app. The accessor methods for database fields are
generated automagically from the database schema.

It’s also probably using either the restful_authentication plugin, or
it’s
older brother acts_as_authenticated, both of which normally use
crypted_password, instead of hashed_password for the field name,
although I
beleive that this can be overridden when the authentication code is
generated.

I’m pretty sure that Hassan S. has the right diagnosis.
undefined local variable or method `hashed_password’ for #<User id: nil,
login: “”, email: “”, hashed_passwd: nil>

This indicates that the database column is named hashed_passwd NOT
hashed_password, so ActiveRecord isn’t providing a method with the name
hashed_password.

This is the kind of question which would probably be answered much more
quickly, and with less confusion on the rails mailing list.

Rick,
Thanks for the resources. I will use the mailing list next time.
You were right - I figured out before seeing your post. I submitted the
new user request and was able to look at the error messages from the
web server which led me to take a second look at the database.

Sure enough there was a field spelling error as you pointed out.
Thanks again!
