error message after upgrading to Gusty Gibbon Ubuntu

I have started to get the error message "wrong number of arguments (1
for 0)" since I upgraded to Gusty Gibbon.

I am new to ROR so I have no clue.

This is the code that was running
  def create
    @user = User.new(params[:user])
    if @user.save
      flash[:notice] = 'User was successfully created.'
      redirect_to :action => 'list'
    else
      render :action => 'new'
    end
  end

andf this is the stack trace any help would be appreciated

I have started to get the error message "wrong number of arguments (1
for 0)" since I upgraded to Gusty Gibbon.

I am new to ROR so I have no clue.

This is the code that was running
  def create
    @user = User.new(params[:user])
    if @user.save
      flash[:notice] = 'User was successfully created.'
      redirect_to :action => 'list'
    else
      render :action => 'new'
    end
  end

andf this is the stack trace any help would be appreciated

Well there'a clearly something interesting happening here

app/models/user.rb:17:in `initialize'
app/models/user.rb:17:in `new'
app/models/user.rb:17:in `hashed'
app/models/user.rb:35:in `update_password'

but you haven't shown us what's in that file so it's hard to guess what might be wrong

Fred

Here is the model users.rb

class User < ActiveRecord::Base

  has_and_belongs_to_many :groups

  attr_accessor :password
  attr_protected :hashed_password

  validates_uniqueness_of :username

  validates_confirmation_of :password,
    :if => lambda{|user| user.new_record? or not user.password.blank?}

  validates_length_of :password, :within => 6..20,
    :if => lambda{|user| user.new_record? or not user.password.blank?}

  def self.hashed(str)
    Digest::SHA1.new(str).to_s
  end

  # If user matching the credentials is found, return User object
  # if no matching user is found, return nil
  def self.authenticate(user_info)
    user = find_by_username(user_info[:username])
    if user && user.hashed_password == hashed(user_info[:password])
      return user
    end
  end

  private
  before_save :update_password

  # Updates the hashed_password if a plain password was provided
  def update_password
    if not password.blank?
      self.hashed_password = self.class.hashed(password)
    end
  end

end

Hope this helps.
