Question

Right now I have some functionality working but its really ugly and I know there’s a better way to do it.

Here’s what I have right now in my User model:

def attending
dayseventsusers=self.days_events_users
daysevents=Array.new
events=Array.new

dayseventsusers.each do |deu| 
  daysevents<<DaysEvent.find(deu['days_events_id'])
end

daysevents.each do |de|
  events<<Event.find(de['event_id'])
end

return events
end

I’m trying to get a list of events for a certain group of dayseventsusers records but I have to move through several relationships to accomplish this. What I’d really like to do is something like self.days_events_users.days_event.event, but I don’t know if it can be this simple assuming my relationships are setup correctly.

User model
has_many :days_events_users

DaysEventsUsers model
belongs_to :user
belongs_to :days_event

DaysEvent
has_many :days_events_users
belongs_to :event

The days_events_users object belong to a single days_event, which belongs to a single event. Any suggestions are welcome!

Without having tested this, does the following work:

dayseventusers.collect(&:daysevent).collect(&:event)
