title: Do django Class Based Views, CreateView and UpdateView, clean the data behind the scenes?
body: <p>I know the data is validated. But I can't figure out if the CBV clean the data. When using <code>class className(forms.Form):</code> OR class <code>className(forms.ModelForm)</code> you add (inside your CBV):</p>
  
  <pre><code>def post(self, request):
  form = HomeForm()
      if form.is_valid():
          text = form.cleaned_data['p]
  </code></pre>
  
  <p>Can someone tell me if you have to also clean your data manually of if the CreateView and UpdateView clean the data behind the scenes?</p>
