Error message after upgrading to Gusty Gibbon Ubuntu

Rails
1

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

ArgumentError in Access/userController#create

wrong number of arguments (1 for 0)

Well there’a clearly something interesting happening here

app/models/user.rb:17:in initialize' app/models/user.rb:17:innew’
app/models/user.rb:17:in hashed' app/models/user.rb:35:inupdate_password’

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

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.
