Question

我差不多将Objective-C iOS应用程序从Parse.com迁移到自托管的Parse-Server。但是在进行一些检查时，我注意到我的云功能Parse.Cloud.beforeSave没有执行，或者至少没有完成所有工作。 为什么？

我想要添加记录的集合（MyCollection）按预期更新，但我有第二个集合（用于簿记）我更新（以保留最后插入的项目的数量）的方式和那个没有完成。

供参考，这是功能代码：

Parse.Cloud.beforeSave
("MyCollection", function(request, response)
 {
 var queryConfig;

 var queryConfig = new Parse.Query("BooKeep");
 queryConfig.find({
                  success: function(resultConf) {
                  request.object.set("..", resultConf[0].get("...")+1); // This is done as expected.
                  resultConf[0].set("...", resultConf[0].get("...")+1); // Not done!
                  request.object.set("...", resultConf[0].get("...")+1); // This is done as expected.
                  resultConf[0].set("....", resultConf[0].get("...")+1); // Not done!
                  resultConf[0].save(null,{}); // Not done!
                  ....
                  response.success();
                  },
                  error: function() {
                  var reptMsg="The BooKeep-UPDATE procedure failed for some reason.";
                  console.log(reptMsg);
                  response.error(reptMsg);
                  }
                  });
  });

在未来的路上进行更多调查，在日志中显示以下内容。至少现在我知道Parse.Cloud.beforeSave正在运行，我以前不太确定。

我已经能够通过转到_SCHEMA集合并更改：

来使其工作

rails _4.2.5.1_ new my_new_app

为：

    "update": {
        "Yacb6CzuB9": true
    },

为BooKeep班。

我仍然不明白为什么我必须这样做，因为我不需要每个人都拥有更新权利，但事实是它现在有效。如果有人可以评论并表明更好的解决方案，我会很高兴。

Parse.Cloud.beforeSave not working / Parse-Server
