title: Django template: submit form after file upload
body: <p>Hey I have Django model (CharField,CharField,FileField) with fields creating a form like this:</p>
  
  <pre><code>## Form ##
  
   - To (text input)
   - Comment (text input)
   - Attachment (file input)
  
  [submit button]
  </code></pre>
  
  <p>Currently the file is being uploaded when I submit the form. How can I make 'upload button' so the files can be uploaded before I submit the form?</p>
