    a b Django uses different formats for different locales when guessing the format  
    268268used by the user when inputting data on forms. Note that Django uses different
    269269formats for displaying data, and for parsing it.
    270270
     271To enable a form field to localize input and output data simply use its
     272``localize`` argument::
     273
     274    class CashRegisterForm(forms.Form):
     275       product = forms.CharField()
     276       revenue = forms.DecimalField(max_digits=4, decimal_places=2, localize=True)
