Authlogic with Mongoid (in spirit of http://pastie.org/503478)

user.rb

  include Mongoid::Timestamps

  include Authenticable

  acts_as_authentic do |config|
    # Change this to your preferred login field
    config.login_field = 'username'
    config.merge_validates_uniqueness_of_login_field_options :scope => '_id', :case_sensitive => true

user_session.rb

class UserSession < Authlogic::Session::Base
  def to_key
    new_record? ? nil : [self.send(self.class.primary_key)]
  end
end

It's nice~

Love it.

no luck for me. Is this using rails3? Can someone set up a skeleton app?

primary_key returns nil for me ( overridden somewhere else ) ?

I'm sorry, haven't used/changed this since I pasted it. I've switched to MongoMapper and use this snippet to make it work with that. :)

I'm not even sure if you need the ProtectedAttributes module, as Mongoid might support that by itself by now. You could try not including that.

Thanks for the quick response. I've fiddled with it long enough and I think I will just switch to Devise sine I'm using that successfully for another mongoid project. What was the reason you switched to MM instead?

I did try commenting it out, and still got the same issue btw.

primary_key can't override, in Rails 3

On the user model do:

def self.primary_key
  if caller.first.to_s =~ /(persist|session)/
    :_id
  else
    @@primary_key
  end
end

Fixes the errors I had with recent mongoid/authlogic.

Is this still working for people? I'm getting this error:

Authlogic is calling the "where" method with two arguments, which I guess isn't how mongoid works:

where("last_request_at > ?", logged_in_timeout.seconds.ago)

interesting, I'm trying to make the original pastie work with sinatra, but so far no luck, thinking it's almost 2 years old I believe some stuff have evolved
yet something stroke me : your code looks much more modular and doesn't have the part where some methods (callbacks) are generated) is it because of mongoid or just the way you wrote the thing ?

I gave up and switched to Devise :)

Having the same problem like cmelbye, I found out that it is enough to comment out the line
include Authlogic::ActsAsAuthentic::LoggedInStatus
as this sub-module causes the where problem.

Understand where a problem :(

It's new syntax for creating indexes
