forms.BoundField.css_classes()

BoundField.css_classes() [source]

When you use Django’s rendering shortcuts, CSS classes are used to indicate required form fields or fields that contain errors. If you’re manually rendering a form, you can access these CSS classes using the css_classes method:

>>> f = ContactForm(data={'message': ''})
>>> f['message'].css_classes()
'required'

If you want to provide some additional classes in addition to the error and required classes that may be required, you can provide those classes as an argument:

>>> f = ContactForm(data={'message': ''})
>>> f['message'].css_classes('foo bar')
'foo bar required'
