Hi, I have a question   (im using Odoo v9.0 alpha)

ive added a field in 'res_users' by override:

python code:

class res_users(osv.osv):

        _name='res.users'
        _inherit='res.users'
        _columns={

                'testing:fields.selection([('testing1','Testing1'),('testing2','Testing2')],'Testing'),

}
res_users()

xml code: ive added this line

<field name="testing" widget="radio"/>

So we are able to display a 2 radio button like this

o Testing1                                Option 1

o Testing2                                Option 2

is it possible to generate (n) number of options for my radio button (earlier there are only 2 options) now i want  for example, the number of records in my customize module is 4 how will i edit my definition here so it will be depending on the number of records of my customize module       'testing:fields.selection([('testing1','Testing1'),('testing2','Testing2')],'Testing'),
