title: How can I change display of visible value in django form?
body: <p>I have Django model from external python library:</p>
  <pre><code>class Item(models.Model):
    name = models.CharField(...)
    serial = models.CharField(...)
  
    def __str__(self):
      return str(self.name)
  ...
  </code></pre>
  <p>I can't change this model, but I want to display on my form widget with value as
  &quot;<strong>Item Name (Item Serial)</strong>&quot;</p>
  <p>My form is very simple:</p>
  <pre><code># forms.py
  class InventoryForm(forms.ModelForm):
  
      class Meta:
          model = Inventory
          fields = ('title', 'item',)
  </code></pre>
  <pre><code># models.py
  
  class Inventory(models.Model):
    title = models.CharField(...)
    item = models.ForeignKey(to='Item'...)
  ...
  </code></pre>
  <p>Can I change display of visible value?</p>
