I know that solution, but the rest routes plugin is different. it makes it for non-devs a lot easyer to do query's.
Think about it.
Buildingthe fields and posts with metabox.
Building a easy clickable query to filter or to build a awesome form without any coding or any snippet (even if it is a snippet then it can be a created code what someone can copy paste). Or creating a query and BAM getting all the information with a shortcode in a smooth datatable view! You want a clickle link? BAM assign it from that tool and say you want to open view that belongs to that post.
