title: How can I use different form widgets in Django admin?
body: <p>I tried with something like:</p>
  
  <pre><code>class PedidoForm(forms.ModelForm):
      class Meta:
          model = Pedido
          widgets = {
              'nota': forms.Textarea(attrs={'cols': 80, 'rows': 20}),
          }
  </code></pre>
  
  <p>But it changes in both, list view and single object view. I'd like to change int only for the single object view. HOw can I do it?</p>
  
  <p>I want this:</p>
