FindHasMany calls buildURL using the parent type/id

[igorT]

It's a bug that we do that here
https://github.com/emberjs/data/blob/master/packages/ember-data/lib/adapters/rest_adapter.js#L410

@igorT The url in description is broken. Any update on how to proceed with this?

@karanjthakkar I believe this is an updated link:

data/packages/ember-data/lib/adapters/rest-adapter.js

Line 493 in 56196f6

url = this.urlPrefix(url, this.buildURL(type, id, null, 'findHasMany'));

I might have time to dig into this. Is it still without contributor?

[Serabe]

Digging into this issue, I see that the constructed URLs for hasMany and belongsTo relationship are indistinguishable from the one to get the parent type.

In build-url-mixin, urlForFindHasMany and urlForFindBelongsTo only receive an id and a modelName; there is no relationship information available. As of JSONAPI specification, the suggested relationship URL with the related data looks like /parentType/id/relationshipName: there are at least one

On the other hand, the adapter.buildURL = function() {...} in some test leaks to the rest of the tests.

@wecc this should be combined with whatever other issues we have around fixing hasMany relationships to always hit findHasMany and urlForHasMany

Yeah, I'm closing this in favor of #2162.
