解析PFQuery whereKey：notEqualTo不能用于PFUser对象 [英] Parse PFQuery whereKey:notEqualTo is not working for PFUser objects

问题描述

我认为这是Parse的一个错误，但我不知道在哪里报告它。

I think this is a bug in Parse, but I don't know where to report it.

我使用Parse与Swift。我有一个 PFQueryTableViewController 。

I'm using Parse with Swift. I have a PFQueryTableViewController.

在我的 queryForTable ， CAN 可以使用以下查询：

In my queryForTable function, I CAN use this following query just fine:

query.whereKey(kHWActivityFromUserKey, equalTo: User.currentUser())

但是，当我改变 equalTo 到 notEqualTo ，如下所示：

However, when I change equalTo to notEqualTo, like this:

query.whereKey(kHWActivityFromUserKey, notEqualTo: User.currentUser())

...然后表保持空白没有。 （它甚至不显示空行。）

... then the table stays blank and just does nothing. (It does not even show empty rows.)

我试图找出发生了什么，所以我采取了这个查询，我调用 findObjectsInBackgroundWithBlock 手动地查看块中的对象和错误令人惊讶的是，该块从未被调用！

I tried to figure out what was going on, so I took that query and I called findObjectsInBackgroundWithBlock on it manually, to look at the objects and error inside the block. Surprisingly, the block was never called!

所以我在主线程上运行查询，如下：

So then I ran the query on the main thread, like this:

    var error = NSErrorPointer()
    var objects = query.findObjects(error)

当我运行这个程序时，我的整个应用程序崩溃，出现以下异常：

When I ran this, my whole app crashed with the following exception:

2015-02-11 13:26:45.339 HDWR[18996:3057150] 
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', 
reason: 'Couldn't create cache key from 
<PFUser: 0x7f8e885de7c0, objectId: X7lSc1Gajm, localId: (null)> {
...

所以我认为有一个与缓存有关的错误， whereKey：notEqualTo 与 PFObject 。

So I think there is a bug related to caching whenever I use whereKey:notEqualTo with a PFObject.

ve还尝试在查询中使用 objectId 字符串，如下所示：

I've also tried using the objectId string in the query instead, like this:

    query.whereKey(kHWActivityFromUserKey, notEqualTo: User.currentUser().objectId)

只是给我一个指针错误：

But then Parse just gives me a pointer error:

2015-02-11 13:45:46.550 HDWR[19708:3069545] 
Error: pointer field fromUser needs a pointer value (Code: 102, Version: 1.6.0)

我如何报告这个bug到Parse？或者你有任何想法的解决方法？我们需要在我们的应用程序中有这个逻辑。

How can I report this bug to Parse? Or do you have any idea for a workaround? We kind of need to have this logic in our app.

推荐答案

这是Parse iOS SDK中的一个错误， c $ c> 1.6.1 。它似乎固定在 1.6.2 中。

This was a bug in the Parse iOS SDK, version 1.6.1. It appears to be fixed in 1.6.2.
