I wrote the below code

    if (len(get_vars) > 0):
        (dummy, template_id) = get_vars.viewing.split('.')
    else:
        template_id = request.args[0]
    def postp(r, output):
        if r.interactive:
            template_id = r.id
            form = s3db.survey_buildQuestionnaireFromTemplate(template_id)
            output['items'] = None
            output['form'] = None
            output['item'] = form
            output['title'] = s3.crud_strings['survey_template'].title_question_details
            return output
    s3.postp = postp
    s3db.configure('survey_template', listadd=False, editable=False, deletable=False)
    r = s3_request('survey', 'template', args=[template_id])
    output = r(method='read', rheader=s3db.survey_template_rheader)
    return output
