title: Fill Django Form Field Data with Db Data
body: <p>I am trying pre-fill a form field with data from a Db object. How do you set up the form,view, and model to fill a field with this data?</p>
  
  <p>The goal is to let the user only select data that is queried from the object. Ex. An event has  bands playing, the user selects their favorite band from those at the event.</p>
  
  <p>I tried looking through the docs for form.data  - but can't seem to find what I'm looking for.</p>
  
  <p>Thanks!</p>
