I wrote the below code

    if (not auth.s3_logged_in()):
        session.error = T('Requires    Login!')
        redirect(URL(c='default', f='user', args='login'))
    tablename = 'msg_twitter'
    table = s3db.msg_twitter
    s3.filter = (table.inbound == False)
    table.inbound.readable = False
    s3.crud_strings[tablename] = Storage(title_display=T('Tweet    Details'), title_list=T('Sent    Tweets'), label_list_button=T('View    Sent    Tweets'), label_delete_button=T('Delete    Tweet'), msg_record_deleted=T('Tweet    deleted'), msg_list_empty=T('No    Tweets    currently    in    Outbox'))
    def postp(r, output):
        if isinstance(output, dict):
            add_btn = A(T('Compose'), _class='action-btn', _href=URL(f='compose'))
            output['rheader'] = add_btn
        return output
    s3.postp = postp
    s3db.configure(tablename, editable=False, insertable=False, listadd=False, list_fields=['id', 'date', 'to_address', 'body'])
    return s3_rest_controller(module, 'twitter')
