gistfile1.py

#
# This code inserts the placeholder attribute, using the field's label,
# for all TextInput, Textarea, DateInput, DateTimeInput, TimeInput widgets
# of your ModelForm
#
class MyForm(forms.ModelForm):
    class Meta:
        model = MyModel
    
    def __init__(self, *args, **kwargs):
        super(MyForm, self).__init__(*args, **kwargs)
        for key, field in self.fields.items():
            if isinstance(field.widget, forms.TextInput) or \
                isinstance(field.widget, forms.Textarea) or \
                isinstance(field.widget, forms.DateInput) or \
                isinstance(field.widget, forms.DateTimeInput) or \
                isinstance(field.widget, forms.TimeInput):
                field.widget.attrs.update({'placeholder': field.label})
