Hi all,

I have created a button and wrote function for that like, when i click on that button new pop-up form should open.

xml:

<button name="button_method" string="Test Drive Type" type="object" class="btn-primary"/>

py:

        @api.multi
        def button_method(self):
            view_ref = self.pool.get('ir.model.data').get_object_reference('autochip', 'so_on_form')
            view_id = view_ref and view_ref[1] or False
            return {
                'type': 'ir.actions.act_window',
                'res_model': 'test.drive.allocation',
                'view_type': 'form',
                'view_mode': 'form',
	        'views': [(view_id, 'form')],
                'view_id': view_id,
                'target':'new',
                }

When i click on button i am getting 

TypeError: <built-in function id> is not JSON serializable 

i am not able to find what is the issue?

what is wrong?
