Define relationship resource type in serialization options

For example I have the following blog post with an author, and I want it serialized as a resource of type posts, with an included resource of type users:

{
  id: '12'
  text: 'Check this out!',
  author: {
    id: '42',
    fullname: 'Foo Bar'
  }
}

The only options I’ve found so far is to add a customType: 'users' attribute to my author data and to use typeForAttribute: (attribute, data) => data.customType || attribute option.

But when I already know that all my authors are users, is there a solution to statically tell that to the serializer? Otherwise would it be conceivable to define the relationship type with something like this:

var UserSerializer = new JSONAPISerializer('posts', {
  attributes: ['author', 'text'],
  author: {
    ref: 'id',
    type: 'users'  // <-- new option
  }
});

What do you think ?

@dhautotlf nothing really proper, I used typeForAttribute option to override the type if the relation - found by its name…which won’t work when relations of different types have the same name - had a specific type.

ex (completing my previous example):

// Somehow construct this from your relation structure:
const typesForRelations = {author: 'users'};

// Then, in your serializer options:
typeForAttribute: (attribute, resource) => typesForRelations[attribute] || attribute
