title: Django Form from Model in pure Python
body: <h3>Intro</h3>
  
  <p>I'm trying to create interface to provide easy access to online game data. There are some basic parameters of each hero in the database, created with HeroModel class (using SQLAlchemy).</p>
  
  <h3>Problem</h3>
  
  <p>Also there is need to create <em>Manager</em> class above the Model to change data in its instance (in the <em>Manager</em>), but not in the database. The only way to implement this, as I see now is to rewrite all the Model fields to <em>Manager</em> class. </p>
  
  <p>"Form from Model" mechanism seems like right solution for me.</p>
  
  <h3>Question</h3>
  
  <p>How can I implement this idea in Python?</p>
