[web2py] Forcing minus for converted parameter names in form helpers

[Daniel Gonzalez]

Hi,

I am trying to create a radio component in a custom web2py form, using 
twitter bootstrap styles, as explained 
here<http://twitter.github.com/bootstrap/javascript.html#buttons>
.
In order for the button group to behave like a radio button, we need to 
specify the 'data-toggle="buttons-radio"' modifier.
I have tried to do this in web2py with '_data_toggle="buttons-radio"', but 
web2py is generating data_toggle instead of data-toggle (underscore instead 
of minus).
Is there a way to tell web2py to convert the underscores in the parameter 
names to minus instead of underscore?

This is my code:

def get_bootstrap_radio(options):
    '''<div class="btn-group" data-toggle="buttons-radio">
           <button class="btn" type="button">1</button>
           <button class="btn" type="button">2</button>
           <button class="btn" type="button">3</button>
       </div>'''
    i = []
    for value in options:
         i.append(BUTTON(value, _type="button", _class="btn"))
    return DIV(*i, _class='btn-group', _data_toggle="buttons-radio")

Thanks,
Daniel
