SessionsController＃create中的NoMethodError

Question

Ok, I'm learning R on R from the Pragmatic Bookshelf text Agile Webdevelopment with Rails 4th ed.

I'm at page 212 and I'm getting this error.... NoMethodError in SessionsController#create and app/controllers/sessions_controller.rb:7:in 'create'

I'm pulling my beard out over here, I've spent days trying to track this down. Here is the create code this is pointing to...

def create
  if user = User.authenticate(params[:name], params[:password])
    session[:user_id] = user.id
    redirect_to admin_url
  else
    redirect_to login_url, :alert => "Invalid user/password combination"
  end
end

Can any Guru out there assist?

Sounds like you need the following in your user model (page 203 on my book.) If that is not the issue, please provide your user model too.

def User.authenticate(name, password)
  if user = find_by_name(name)
    if user.hashed_password == encrypt_password(password, user.salt)
      user
    end
  end
end
