Is it possible to connect CanCanCan with Trestle?

[rcholody]

I have used CanCanCan to limit specific action on admin dashboard based on role. I would like to limit some specific CRUD operations on specific model. Is it possible to also render different content on specific role? I have specified ability.rb with for example:

user can :read, Company, id: user.companies.pluck(:id)

and connect load_and_authorized_resource in controller.rb. When I have used command Company.accessible_by(ability) in IRB it give me correct feedback. But how can I connect this functionality to Trestle?

Might help you:

No real support at the moment, but it's planned.

Is not the correct way, but in development works.

# app/admin/users_admin.rb

Trestle.resource(:users) do
  menu do
    item 'Users', icon: 'fa fa-user', group: :agenda
  end

  scope :all, default: true
  
  controller do
    def show
      @user = User.find(params[:id])
      authorize! :read, @user
    end
  end

# app/models/ability.rb
class Ability
  include CanCan::Ability

  def initialize(user)
    user ||= User.new # guest user (not logged in)

    can :create, User
    can %i[read update destroy], User, id: user.id
    can :create, Annotation
    can %i[read update show destroy], Annotation, user_id: user.id
  end
end
