Sin un sistema de validación de datos, tendrías que hacer todas las comprobaciones a mano, en código.

Estas funcionalidades son para lo que fue creado Marshmallow. Es un gran paquete, y lo he usado mucho antes.

<code>package math</code>, which exports function <code>Sin</code>, and
installed the compiled package in the file identified by
<code>"lib/math"</code>.
This table illustrates how <code>Sin</code> is accessed in files
that import the package after the
various types of import declaration.

<pre class="grammar">
Import declaration          Local name of Sin

import   "lib/math"         math.Sin
