ember.js - Ember 2 simple polymorphic relations -

i have notes model want attach 1 of 2 other models, customers , suppliers.

in database have foreigntype , foreignid field holds type , corresponding id customer or supplier,

notes: { {id: 1, body:'bar',foreigntype:'customer',foreignid:100},          {id: 2, body:'foo',foreigntype:'supplier',foreignid:100}        } 

that is, note can attached customer or supplier.

the convention seems field called notetype? have seen tutorial related type nested in json, rather being @ root.

my ember models this:

//pods/note/model.js   export default ds.model.extend({     //...     body: ds.attr('string'),     foreign: ds.belongsto('noteable',{polymorphic:true})   });  //pods/noteable/model.js (is there better/conventional place put file?)   export default ds.model.extend({     notes: ds.hasmany('note')   });  //pods/customer/model.js   import noteable '../noteable/model';     export default noteable.extend({ //derived noteable class      name: ds.attr('string'),      //...    });  //pods/supplier/model.js   // similar customer    // sample incoming json // {"customer":{"id":2,"name":"foobar inc",...},  "contacts":       [{"id":1757,"foreigntype": "customer","foreignid":2,...},      {"id":1753,"foreigntype": "customer","foreignid":2,...},      ...],    ...   "todos":      [{"id":1,"foreigntype":"customer","foreignid":2,"description":"test todo"}],   "notes":      [{"id":1,"foreigntype":"customer","foreignid":2,"body":"some customer note "}] } 

how set correctly, i.e. ember expect?

my notes aren't attaching correctly customer model. show in data tab of ember inspector, notes list of customer empty.

i can see several possibilities:

• extend customer/supplier ds.model , have property notes: belongsto('noteable'), mean belongsto in notes isn't polymorphic, there wouldn't derived classes, noteable itself. not sure if ember (data) can deal nesting correctly.

• extend noteable. if want have other things addresses or contacts, can related customer or supplier?

• create duplicate models customernote/suppliernote, customercontact/ suppliercontact, customer/supplier/employee address. , have backend return filtered table/model name depending on endpoint. don't repeat myself though ....
