Re: Can't manage user model from rails_admin with CanCanCan

[Bryan Rite]

Hi Ludovic,

I don’t use RailsAdmin myself so I’m not 100% sure whats going on, but we don’t specifically check for a User::Permission model in CanCanCan. Your ability file does look fine so I would hazard a guess that the `User::Permission` class is being called from somewhere else.
