Answer 1

I really like Dmitriy Sintsov's answer but it doesn't work. Here's a version that does work:

def __init__(self, *args, **kwargs):
    super().__init__(*args, **kwargs)
    for field in iter(self.fields):
        self.fields[field].widget.attrs.update({
            'class': 'form-control'
    })

update

add this condition for better

if self.fields[field].widget.__class__.__name__ in ('AdminTextInputWidget' , 'Textarea' , 'NumberInput' , 'AdminURLFieldWidget', 'Select'): 
     self.fields[field].widget.attrs.update({ 'class': 'form-control' })
