Looks extremely similar to <a href="https:&#x2F;&#x2F;github.com&#x2F;schematics&#x2F;schematics" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;schematics&#x2F;schematics</a> . Always good to see two projects approach the problem the same way independently - higher chance that the solution is right :)<p>Schematics has a very useful feature in &quot;roles&quot; - i.e. a good way of hiding certain fields in certain situations (e.g. admin views vs self vs other vs anonymous). Does marshmallow have something similar?
