I have a table with 5 columns: handle, fname, lname, password_hash, password_salt, email

#Controller
@user = User.new
@user.handle = params[:user][:handle]
@user.fname = params[:user][:fname]
@user.lname = params[:user][:lname]
@user.email = params[:user][:email]
@user.password = params[:user][:password_hash]

if @user.save
 ...
end

#Model
def password=(pass)
  salt = [Array.new(6){rand(256).chr}.join].pack("m").chomp
  self.password_salt, self.password_hash = salt, Digest::SHA512.hexdigest(pass + salt)
end


#Error Message
 ArgumentError in UserController#create

wrong number of arguments (0 for 5)
