load_and_authorize_resource not loading the index collection in CanCan 2.0

[lserman]

I am trying out CanCan 2.0 for the first time, in order to use ollym's fork for strong parameters.

My controller is namespaced Builder::ContactsController. So in my Ability:

can [:index, :show], :"builder/contacts"

This allows me to bypass the ensure_authorization check and get into my index method. I have included load_and_authorize_resource in the controller, but the @contacts variable is not loaded by CanCan.

Is there something else I need to be doing in CanCan 2.0 to load this resource? I have tried using the class option but that doesn't work either. Also, no calls to load_resource or anything CanCan-related are found in my trace. No SQL for contacts is generated (according to the log) either.

This all works in CanCan 1 using this:

can :read, Contact

I've tried adding the above line to my ability.rb when using CanCan 2, and it still doesn't work.

I can't reproduce this.

Please include the cancan line from your Gemfile.

Does CanCan::ControllerResource#load_collection run? You can open the cancan source (find it with bundle show) and use pry or a puts to find out.

Can you write a failing spec? Or, can you reproduce this starting from rails new and publish the failing app?

I had the same error the problem was that I had defined both a block and a normal ability and expected it to ignore the block. As far as I can think this should not compromise security as long as no cannot blocks are used.

Thanks for your submission! The ryanb/cancan repository has been inactive since Sep 06, 2013.
Since only Ryan himself has commit permissions, the CanCan project is on a standstill.

CanCan has many open issues, including missing support for Rails 4. To keep CanCan alive, an active fork exists at cancancommunity/cancancan. The new gem is cancancan. More info is available at #994.

If your pull request or issue is still applicable, it would be really appreciated if you resubmit it to CanCanCan.

We hope to see you on the other side!
