I'd say RoR is amazing quick to learn and use for other purposes. If one has any experience with REST, then most of the backend communication can be built out of scaffolding.
Most tutorials and guides for RoR teach REST from page 1, so once you have some familiarity with Rails routing, using it as a backend is simple enough.
