ruby on rails 3 - How to set up multiple aliased joins between two models? -


in rails 3.2 app need set 2 associations between same 2 models.

for example

class user   has_many :events   has_many :attendances   has_many :attended_events, through: :attendances end  class event   belongs_to :event_organizer, class_name: "user"   has_many :attendances   has_many :attendees, through: :attendances, class_name: "user" end  class attendance   belongs_to :attended_event, class_name: "event"   belongs_to :attendee, class_name: "user" end 

this first time i've experimented aliasing class names, , i'm having trouble getting work. i'm not sure if issue lies how i've defined associations, or elsewhere.

do associations ok? have overlooked needed work?

the problem i'm having no user ids being set in attendance model. may stupid question, given associations above, should field name :user_id or :event_organizer_id?

really appreciate suggestions on this. thanks!

foreign_key specified in user , event

class user   has_many :events    has_many :attendances, foreign_key: :attendee_id   has_many :attended_events, through: :attendances end  class event   belongs_to :event_organizer, class_name: "user"    # here should event_organizer_id    has_many :attendances, foreign_key: :attended_event_id   has_many :attendees, through: :attendances end  class attendance   belongs_to :attended_event, class_name: "event"    # should have attended_event_id    belongs_to :attendee, class_name: "user"           # should have attendee_id because of 1st param belongs_to here "attendee"   # , same should added foreign_key in user model   # same follows event end
