ruby on rails - Finding all roles for a particular resource instance in Rolify -


how find roles particular resource instance in rolify? documentation suggests following:

forum.find_roles # => [ list of roles binded forum instance or forum class ]

but if want particular forum instance? forum.first.find_roles not work. there way? tried location instead of forum:

2.1.5 :003 > location.first.find_roles   location load (0.3ms)  select  "locations".* "locations"  order "locations"."id" asc limit 1 nomethoderror: undefined method `find_roles' #<location:0x007fbe880d1b48>     /users/scott/.rvm/gems/ruby-2.1.5@rails4/gems/activemodel-4.2.1/lib/active_model/attribute_methods.rb:433:in `method_missing' ... ... ...

location.first.roles should work.
