How can i redirect to other model form view on "Create" button click. I tries that using "view_init", and try to return model name etc, but it didn't work. I tried that code 

def view_init(self, cr, uid, fields_list, context=None):
        return {
            'name': _('Patient Group Lab Test Form'),
			'view_mode': 'form', 
			'view_id': False, 
			'view_type': 'form',
            'res_model': 'oeh.group.lab.test', 
			'type': 'ir.actions.act_window', 
			'target': 'self',
            }

Currently i am on that model "oeh.medical.radiology.report", and i need to open "oeh.group.lab.test" form view on create button click.

Come on odoo developers plz help me, am badly stuck in it
