 <p>Maybe the <code>models</code> module has an <code>__all__</code> which does not include what you're looking for. Anyway, <code>from ... import *</code> is <strong>never</strong> a good idea in production code -- we always meant the <code>import *</code> feature for interactive exploratory use, <em>not</em> production use. Specifically import the module you need -- use that name to qualify names that belong there -- and you'll be vastly happier in the long run!-)</p>
