Question

我有一个从Couchbase服务器同步的couchbase lite数据库。但是当我尝试创建一个视图然后查询它时，我得到一个异常

getViewID（）＆lt; 0，状态：404（HTTP 404 not_found）。

代码是和日志如下：

        db = application.getDatabaseInstance();

        View membersView = db.getView("membersView");
        if (membersView == null) {
            membersView.setMap(
                    new Mapper(){
                        @Override
                        public void map(Map<String, Object> document, Emitter emitter) {
                            Log.e("inside map", "map");
                            Object fname = document.get("FatherName");
                            if (fname != null)
                                emitter.emit((String) document.get("Id"), document);
                        }
                    }, "2" /* The version number of the mapper... */
            );
        }
        Query query = membersView.createQuery();
        query.setMapOnly(true);
        QueryEnumerator result = query.run();
        Log.e("here", "here");
        for (Iterator<QueryRow> it = result; it.hasNext(); ) {
            QueryRow row = it.next();
            Log.e("row", (String) row.getValue());
        }

这是日志：

我没有使用CBL的Java版本，因此我不知道该特定异常的含义。但是，您的代码有一个错误：您只在第一次创建视图时设置视图的地图功能（sum(np.array([[[2,3,4],[4,5,6]],[[7,8,9],[10,11,12]]])) Out[47]: array([[ 9, 11, 13], [14, 16, 18]]) np.sum(np.array([[[2,3,4],[4,5,6]],[[7,8,9],[10,11,12]]]), axis=0) Out[48]: array([[ 9, 11, 13], [14, 16, 18]]) np.sum(np.array([[[2,3,4],[4,5,6]],[[7,8,9],[10,11,12]]])) Out[49]: 81）。这是不正确的。视图是持久的，但是map函数（因为它实际上只是一个任意函数）并不是。这意味着每次运行应用程序时，必须在第一次查询视图之前注册地图功能。

获得异常＆＃34; getViewID（）＆lt; 0，状态：404（HTTP 404 not_found）＆＃34;在Android应用程序
