title: Pseudo-form in Django admin that generates a json object on save
body: <p>I have a model with a field for a json object. This object is used on the site to control some css variables, among other things. </p>
  
  <p>Right now in the admin, I have a text field where a user can save a json object. I'd like to show a form with all the attributes that, upon saving, will generate a json object.</p>
  
  <p>Basically, the user sees, and the data is stored, like this:</p>
  
  <pre><code>{
      "name":"hookedonwinter",
      "user-id":123,
      "basics":{
          "height":150,
          "weight":150
          }
  }
  </code></pre>
  
  <p>And I'd rather have the user see this:</p>
  
  <pre><code>Name: &lt;input field&gt;
  User Id: &lt;input field&gt;
  Height: &lt;input field&gt;
  Weight: &lt;input field&gt;
  </code></pre>
  
  <p>and the data still be stored in json.</p>
  
  <p>Any guidance would be appreciated. Links to docs that explain this, doubly appreciated. </p>
  
  <p>Thanks!</p>
