clean_data and cleaned_data

When we use the form object in Django,Frequently,we need validate the fields of the form.for example:

>>>python manage.py shell
>>>from pageage1 import MyForm
>>>form=MyForm({'username':'Eric','email':'test@test.com'})
>>>form.is_valid()
True

We could access the form's data by attribute form.data, If it's validated we can also access the valid data by attribute form.clean_data,but when you upgrade to Django 1.0,this attribute will be no long in use.Instead of it,you should use the attribute cleaned_data:

...
>>>form.clean_data # Django 0.96
>>>form.cleaned_data # Django 1.0
