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

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.
