Rails Admin's use of cancan(can) is incorrect and is erroring with v2

[hlascelles]

When loading the main dashboard, the cancan(can) adapter tries to authorise(:dashboard, nil).

Not passing in any model (the nil) is incorrect use of cancancan, according to a maintainer.

Can we change the authorise to pass in :rails_admin as the "model"? I understand this is a breaking change. Perhaps do it if cancancan is seen to be v2 or higher?

Bump.

We're working around this for now by using a separate ability class for the rails_admin gem.

I don't understand how using a separate ability class would solve this problem. This new adapter class does tho: CanCanCommunity/cancancan#413 (comment)

I'm trying to figure out how to install this new adapter/extension for cancancan. Where do I place it in the project?
