title: django form input range how to show value?
body: <p>I have a question about range input in Django 2.
  How can I display the current value of the input range slider?
  Now its only slider without any values. Maby I should save value every time it changes, but I'm looking for simplicity. </p>
  
  <p>Form:</p>
  
  <pre><code>scale = forms.IntegerField(widget=forms.NumberInput(attrs={'type':'range', 'step': '5', 'min': '-100', 'max': '100'}), required=False)
  </code></pre>
  
  <p>Template:</p>
  
  <p>{{form.scale}}</p>
