Specs
exists?(Plug.Conn.t()) :: true | false
Check if the requested entity exists.
This is a great place to actually fetch the requested resource,
then return it as a map so it can be merged into the :assigns
map of the request.
Returning false
here will cause the plug to return a 404 Not Found response.
