If you would like to programatically include the css class (or indeed, any other attributes) to the form field, then you can use the render_kw argument.

eg:

r_field = RadioField(
    'Label', 
    choices=[(1,'Enabled'),(0,'Disabled')], 
    render_kw={'class':'myclass','style':'font-size:150%'}
)

will render as:

    
 Enabled
    
 Disabled
