Are relations supposed to work with inheritance?

[thokari]

Hi again,

say I have a model that extends another model, like StaffUser and User for example.
Now when I set it up like the examples suggest, but also have StaffUser extends User, then, besides still having the problem, that the foreign keys for the relationships do not get set properly (#48), my 'Address' instance (when assigning a 'StaffUser' instance to its 'user' property) now has two fields, user_id and staff_user_id (both 'null' as of issue mentioned before).

I realise this is a complex issue, and coming from an object oriented background I might be expecting too much.
However your software looks very promising, and even without this feature it would save a lot of boilerplate code.

Thanks for your help!

Hi Thomas,

I believe we have only been testing the mapping of one model to one table up until now.

Let's leave this issue open and we will write tests for this scenario and try to get them working consistently across database variants.

For now, you should be able to manually merge the schema using something like (I haven't tested this code):

_ = require 'underscore'

class User extends (require 'backbone').Model
  schema: 
    field_1: []

class StaffUser extends User
  schema: _.extend {
    field_2: []
  }, (new User).schema().raw
  sync: (require 'backbone-mongo').sync(StaffUser)

We'll let you know when we've made this a little simpler....
