Module: Draper::Compatibility::ApiOnly

Extended by:

ActiveSupport::Concern

Defined in:

lib/draper/compatibility/api_only.rb

Overview

Draper expects your ApplicationController to include ActionView::Rendering. The ApplicationController generated by Rails 5 API-only applications (created with rails new --api) don't by default. However, including ActionView::Rendering in ApplicatonController breaks render :json due to render_to_body being overridden.

This compatibility patch fixes the issue by restoring the original render_to_body method after including ActionView::Rendering. Ultimately, including ActionView::Rendering in an ActionController::API may not be supported functionality by Rails (see Rails issue for more detail: https://github.com/rails/rails/issues/27211). This hack is meant to be a temporary solution until we can find a way to not rely on the controller layer.
