Overview

This Railtie exposes some configuration options:

  • ‘config.graphiti.handled_exception_formats`, defaulting to `[:jsonapi]`. Formats in this list will always have their exceptions handled by Graphiti.

  • ‘config.graphiti.respond_to_formats`, defaulting to `[:json, :jsonapi, :xml]`. When Responders is included in a controller it will respond to these mime types by default.
