Inclusion of Related Resources (include params) on POST/PATCH requests

[thibaudgg]

At the end of Inclusion of Related Resources JSONAPI spec section it's mentioned:

Note: This section applies to any endpoint that responds with primary data, regardless of the request type. For instance, a server could support the inclusion of related resources along with a POST request to create a resource or relationship.

In the current JR implementation, I think that only FindOperation and ShowOperation support the include params. Correct?

Would it make sense to add support on other endpoints?

If have the case where we want to create an object and get related resources in the response. Something like: POST /articles?include=author.articles (create an article and get all existing articles from the same author).

Am I getting the spec wrong?

Actually, the case is that JR already supports using include in POST/PATCH requests, too. I am able to confirm that from the current (ce94ced) master version, and on v0.7.0, too. https://github.com/venuu/jsonapi-authorization even authorizes such includes properly. master version of JR has a bug, I think, in where it doesn't pass the params[:include_directives] properly downstream to processors. See venuu/jsonapi-authorization#24 (comment) for more details if you're interested — I'm gonna open up a new issue here for this particular case, though, and try to fix it.
