title: How can I receive a JSON:API post of nested attributes in Ruby on Rails?
body: <p>Is there a “standard” approach to receiving (potentially nested) a JSON:API POST object in Rails? </p>
  
  <p>The JSON:API spec uses the same format for GET / POST / PUT, etc, but rails seems to need *_attributes and accepts_nested_attributes_for. These seem incompatible.</p>
  
  <p>I feel like what I'm doing must be somewhat common, yet I'm having trouble finding documentation. I'm wanting to use a React/Redux app that communicates with a Rails app using the JSON:API spec. I'm just not sure how to handle the nested associations.</p>
