Rails 5 api-only ignoring rabl files

[willc0de4food]

I wrote an API app in Rails 4.2 and used rabl to render output. I've recently update the app to use Rails 5 (generated a new app and copied the code over), and since then - all of my API calls get an empty response. I've put a debugger in the controller code to ensure that there is data to render. Does rabl work with Rails 5?

Rails - 5.0.2
Rabl - 0.13.1

Getting an empty response. Works fine when we manually render the JSON using .to_json method like:

render json: @post.to_json

Someone commented this here and then deleted it. Adding it here as reference since it solved this issue.

Adding gem 'jbuilder', '~> 2.5' to the Gemfile solves this. No idea how jbuilder and rabl are related.

Example app that hits this bug: https://github.com/droberts-ada/rabl-test-app

The problem appears to be that in API mode all of the view functionality is stripped out, including all the code that glues together controllers and views. The reason that including the jbuilder gem works is they have a railtie to add a bunch of that back in:

rails/jbuilder@29c0014

Might be this is a pretty straightforward fix.
