Rails 3 using devise and best_in_place gem, will not update subscriber model
===

I have a rails 3 application using devise with the subscribers model.  I would like the subscribers to update their account information in place using best_in_place gem, but I can't seem to get it to update the database.  It will update on the screen, but not the database.

The error sees to suggest the subscriber existing is a bad thing, but it isn't since it would be impossible to update that subscriber if it didn't exist.  

All I want to do is be able to allow the users to update their information in place from a the subscriber/accounts#show page that shows them their details.

my subscriber/accounts controller has this:

        def update
          @subscriber = Subscriber.find(current_subscriber.id)
          @subscriber.update_without_password(params[:subscriber])
        end


I always get these results in the server log:


    Processing by Subscribers::AccountsController#update as JSON
    Parameters: {"subscriber"=>{"firstname"=>"Aarof"}, "authenticity_token"=>"Sx6kEQy4NC56ovikMs/D9nVPGJt1q5jNCoFnNjFhDu8=", "id"=>"2"}

    CACHE (0.0ms)  SELECT `subscribers`.* FROM `subscribers` WHERE `subscribers`.`id` = 2 LIMIT 1
    (0.2ms)  BEGIN
    Subscriber Exists (0.4ms)  SELECT 1 AS one FROM `subscribers` WHERE (`subscribers`.`email` = BINARY 'frostsquid@yahoo.com' AND `subscribers`.`id` != 2) LIMIT 1
    (0.1ms)  ROLLBACK
    Redirected to http://localhost:3000/subscribers/accounts/2
    Completed 302 Found in 12ms (ActiveRecord: 2.6ms)


my show page looks like this: 

    %p.subscriber-account-info
      =best_in_place @subscriber, :firstname, :path => subscribers_account_path(@subscriber)

My routes for subscribers looks like:  


           subscribers_accounts GET    /subscribers/accounts(.:format)                  subscribers/accounts#index
                                POST   /subscribers/accounts(.:format)                  subscribers/accounts#create
        new_subscribers_account GET    /subscribers/accounts/new(.:format)              subscribers/accounts#new
       edit_subscribers_account GET    /subscribers/accounts/:id/edit(.:format)         subscribers/accounts#edit
            subscribers_account GET    /subscribers/accounts/:id(.:format)              subscribers/accounts#show
                                PUT    /subscribers/accounts/:id(.:format)              subscribers/accounts#update
