attendance_count is not an attribute of organization, it is an attribute of attendee so would need something like Training.organizations.first.attendees.first.attendance_count An organization has many attendees so for each organization there are many values of attendance_count. Which makes me realise that the table example you posted does not make sense, as each organization must have multiple rows. If that is not the case then I do not understand your associations. Perhaps you had better tell us exactly what associations you have setup, in terms of has_many, belongs_to has_many_many through etc. Tell us what you have declared for each model.
