ruby on rails 4 - custom instance variable name in cancan's load_and_authorize

users_controller.rb

class userscontroller < applicationcontroller     def index     @objects = user.filter(params: params)   end end

q.1 > if 'load_and_authorize_resource' called instance variable load ?
q.2 > if loads @user or @users how make load on @object ?

i think i'm lacking sufficient knowledge understanding cancan (i'm rails newbie) , using since last 4 days, hoping question makes sense.

a resource not loaded if instance variable set. makes easy override behavior through before_filter on actions - cancan https://github.com/ryanb/cancan/blob/master/lib/cancan/controller_additions.rb line 34 , 35, can in controller --

before_filter :set_instance_variable   load_and_authorize_resource   private     def set_instance_variable     @object = "blah blah blah"     end

load_and_authorize_resource should called after setting instance variable i.e. after 'before_filter :set_instance_variable'
