Question

Given the following example:

class AnonymousSession << Struct.new(:location, :preferences)
  def valid?
    ...
  end
  def new_record?
    ...
  end
end

While this interface is sufficient to create resourceful form and so on, it fails as soon as I want to save my form data to the session:

if session[:user] = AnonymousSession.create(params[:anonymous_session])
  #--> fails with "unknown key(s): location..."
  ...
end

The error message is about "unknown keys". Any clue how to make it work? I just need anonymous sessions without database backend. They are completely disposable due to their short live nature.

Maybe my approach is wrong anyway and there s already an elegant solution to using anonymous sessions? I had a look at AuthLogic but any example I found always comes with an ActiveRecord model (and thus bound to a database).

Answer 1

I have used this solution, where my model derives from Tableless. I think it will work in your case as well.

Answer 2

Ryan Bates has a couple Railscast episodes that might help you out: Session Based Model and Super Simple Authentication.

Answer 3

You d have to explain more as to what you re trying to accomplish. Why couldn t you just create an AnonymousSession class in /app/models?

class AnonymousSession

  attr_accessor :location, :preferences

  def new_record?
   # ...
  end

  def valid?
   # ...
  end

end
