.where-query on "grandparent" in nested models in Rails -

is possible follwing query, without 2 models having direct association:

event.where(community_id: 1) 

these 3 models:

class community < activerecord::base   has_many :organizers end  class organizer < activerecord::base   belongs_to :community   has_many  :events end  class event < activerecord::base   belongs_to :organizer end 

the closest i've come use "delegate" following, works event.communities not query:

delegate :community, :to => :organizer, :allow_nil => true 

you can this:

event.joins(organizer: :community).where("communities.id = ?", 1) 

or:

event.joins(:organizer).where("organizers.community_id = ?", 1)
