[Fixed]-Using cleaned_data on forms in django

It is not necessary to use the .cleaned_data attribute of a form before passing the input values, it will raise an AttributeError if you do it before calling .is_valid() in a bound form or if you try to access it in an unbound form, read more about Form.cleaned_data .

Also, it is usually a good idea to abstract the use of the form’s data in a form method in order to encapsulate logic

In your views, the traditional way you should be using forms is like this:

if request.method == 'POST':
  form = MyForm(request.POST) # Pass the resuest's POST/GET data
  if form.is_valid():         # invoke .is_valid
    form.process() # look how I don't access .cleaned_data in the view

in your form:

class MyForm(forms.Form):
  my_field = forms.CharField()

  def process(self):
    # Assumes .cleaned_data exists because this method is always invoked after .is_valid(), otherwise will raise AttributeError
    cd = self.cleaned_data 
    # do something interesting with your data in cd
    # At this point, .cleaned_data has been used _after_ passing the POST/GET as form's data
