新 ParseObject 的 SetReadAccess 错误 [英] SetReadAccess error for new ParseObject

问题描述

我在我的 Android 应用程序的应用程序类中放置了以下代码:

I have the following code placed in my application class of an Android app of mine:

// Register ParseObject subclasses
ParseObject.registerSubclass(Results.class);

// Set up Parse
Parse.enableLocalDatastore(MyApplication.this);
Parse.initialize(MyApplication.this, PARSE_APP_KEY, PARSE_CLIENT_KEY);
ParseUser.enableAutomaticUser();
ParseACL defaultACL = new ParseACL();
ParseACL.setDefaultACL(defaultACL, true);

每当我重新安装我的应用程序并创建新的结果对象时，这似乎都很有效.现在，如果我通过 Play 商店更新我的应用程序，或通过 Android Studio 安装它，每当创建新的 Results 对象或任何其他 ParseObject 或其子类时，我都会收到以下错误:

This seems to work great whenever I have a fresh install of my app and I create new Results objects. Now, if I update my app via the Play store, or install over it via Android Studio, I get the following error whenever new Results objects, or any other ParseObject or subclass thereof, are created:

java.lang.IllegalArgumentException: cannot setReadAccess for a user with null id

这是 Parse 的错误吗?我在离线 Todo 示例中得到了相同的结果.

Is this a bug with Parse? I get the same results with the Offline Todo example.

推荐答案

您需要确保保存当前用户.

You need to make sure to save the current user.

// Register ParseObject subclasses
ParseObject.registerSubclass(Results.class);

// Set up Parse
Parse.enableLocalDatastore(MyApplication.this);
Parse.initialize(MyApplication.this, PARSE_APP_KEY, PARSE_CLIENT_KEY);
ParseUser.enableAutomaticUser();
ParseUser.getCurrentUser().saveInBackground(); // <--- This Line
ParseACL defaultACL = new ParseACL();
ParseACL.setDefaultACL(defaultACL, true);

不完全确定我的语法，我只在 Swift 中完成过.

Not entirely sure about my syntax, I've only done it in Swift.
