Multiple relationships to the same model

[chieffancypants]

Have you given much thought as to how to define multiple relationships to the same model? For example:

GET /document/1

{
  id: 10,
  name: 'My Awesome Document',
  created_by: {
    id: 5,
    name: 'John Anderson'
  },
  modified_by: {
    id: 7,
    name: 'Wes Cruver'
  }
}

Both created_by and modified_by may relate to the users model, but as far as I can tell, there's no way to do this with the current way of defining relationships.

A backward-compatible way might be to allow an array:

DS.defineResource({
  name: 'document',
  relations: {
    belongsTo: [
      {
        user: {
          localField: 'created_by',
          localKey: 'userId'
        }
      },
      {
        user: {
          localField: 'modified_by',
          localKey: 'userId'
        }
      }
    ]
  }
}

Thoughts?

Yes, for some reason it never occurred to me that one might have multiple relationships of the same type to the same resource. Obviously, it won't work with the current implementation. Your suggested fix is exactly what would need to be done. Would you care to take a crack at it?

Hacking on angular-data is easy: clone it, npm install; bower install, then in one terminal: grunt go, then in another: grunt karma:dev.

I would maybe be able to get to this in 2 days.

Sure, I'll take a quick looksee
