No documented method to render with relationship linkage but no included items

[quickdudley]

I am developing a rails application using jsonapi-rb 0.5.0 (jsonapi-serializable 0.3.0).

In the relevant serializer I have:

belongs_to :programme

For the index method in the controller: this gives the desired behavior. For the get method I need to include the programme relationship linkage, but without populating the included array in the jsonapi response.

I've only been able to discover these two options: none of which are currently acceptable:

1. Using linkage always: true in the serializer: this is the only way to get the required response from my controller's get method, but this approach is unacceptable because it does the same thing in the index method

2. Using the include hash parameter to the call to render in my controller. This approach is unacceptable because it populates the included array with a large, safely cacheable object.

I am running into the same issue.

Same issue, this seems like a big miss. Any workaround you guys have found @thomascchen @quickdudley ?
