title: Django Inline Formsets using custom form
body: <p>I am using inline formsets.</p>
  
  <p>My model:</p>
  
  <pre><code>class Author(models.Model):
      description = models.CharField(max_length=100)
  
  class Book(models.Model):
      author = models.ForeignKey(Author)
      details = models.CharField(max_length=100)
  
  class AuthorForm(ModelForm):
      class Meta:
          widgets = {
              'description': Textarea(attrs={'cols': 40, 'rows': 4}),
          }
  </code></pre>
  
  <p>In my views.py I made the form from the AuthorForm like so</p>
  
  <pre><code>form = AuthorForm(request.POST)
  </code></pre>
  
  <p>But I also made a formset for the Books</p>
  
  <pre><code>InlineFormSet = inlineformset_factory(Author, Books)
  </code></pre>
  
  <p>I cannot pass in a BooksForm with widgets, so how do I add a textarea widget to the book details.</p>
  
  <p>Is it even possible? Am I missing something obvious?</p>
