[Question] Is there an option to omit optional members of a resource (links)

[pixelhandler]

In a resource object I'd like to omit the links object, see http://jsonapi.org/format/#document-resource-objects

I have a long list of objects with one attribute and only need the id, type and attributes members of the resource object.

Is there an option to omit optional members of a resource (links)?

[lgebhardt]

There isn't an option for excluding links, though it's a good idea. We should probably add this as a global configuration option, and also allow it per resource.

👍

in the meantime, what's the best way of getting this done in the application layer? subclass the serializer and override #serialize_to_links_hash?

[mecampbellsoup]

@lgebhardt @clumsysnake any ideas on this? Having same issue, i.e. would like to omit links object from the serialized response object produced by an API endpoint.

[lgebhardt]

I haven't worked on this feature yet. I don't have a good work around at this point.

[mecampbellsoup]

@lgebhardt how about just making it an option that can be passed to serialize_to_hash? Or adding it as an include_directive? https://github.com/mecampbellsoup/jsonapi-resources/blob/c358cb7515441ee7a958b37bcc3be44acc05d0ef/lib/jsonapi/resource_serializer.rb#L46

@lgebhardt if you can point me in the right direction I'll take a shot at implementing this, we really need it 😅

I get around this by specifying the fields I want. Not sure if it's supposed to work like this or not, but:

machines?fields[machines]=name

produces:

{
  "data": [
    {
      "id": "1",
      "type": "machines",
      "links": {
        "self": "http://my.api.com/machines/1"
      },
      "attributes": {
        "name": "M1"
      }
    },
    {
      "id": "2",
      "type": "machines",
      "links": {
        "self": "http://my.api.com/machines/2"
      },
      "attributes": {
        "name": "M2"
      }
    },
    {
      "id": "3",
      "type": "machines",
      "links": {
        "self": "http://my.api.com/machines/3"
      },
      "attributes": {
        "name": "M3"
      }
    }
...

If you need any of the related resources, include them as well. It's ugly but does cut down on payload sizes when you don't need related resources.

after PR #893 it will be possible to allow resource to decide if his relationships has links.

For example: add options to relationships like include_self_route and include_related_route, and make jsonapi_relationships, jsonapi_related_resource(s) and jsonapi_link(s) respect these options

default values for include_self_route and include_related_route can be stored in JSONAPI.configuration
