Question

I’m working on an application that allows users to generate university schedules and then edit them side-by-side with a friend.

The following 3 models exist in the app:

User
 - has_many schedules
 - has_many sidebysides

Schedule
 - belongs_to user
 - has_many sidebysides

SideBySide
 - belongs_to user1
 - belongs_to user2
 - belongs_to schedule1
 - belongs_to schedule2

The parent-child relationships look as follows:

User IS PARENT OF schedules, sidebysides
Schedule IS PARENT OF sidebysides AND IS CHILD OF user
SideBySide IS CHILD OF user1, user2, schedule1, schedule2

I have a feeling I’m approaching this wrong. How might I create the relationships explained above?

Answer 1

Something like:

belongs_to :user1, :class_name => "User"
belongs_to :user2, :class_name => "User"

You can’t do belongs_to user1 since user1 is an instance of User. Same applies to Schedules
