Firebase值未被删除(Firebase value not being deleted)

Firebase值未被删除(Firebase value not being deleted)

我试图从Firebase删除一个孩子，但是，由于某种原因，它没有删除它。

这就是我如何删除它（我得到正确的参考）：

FIRDatabase.database().reference().child("posts").child(commentsArray[indexPath.row].key).removeValue()

如果我尝试po这个值输出是例如：

https://snuspedia.firebaseio.com/posts/coments/-KTzfD1wOa9sRXw93gAF

这是这个：

难道我做错了什么？

I tried to delete one child from Firebase, however, it is not removing it for some reason.

This is how I tied to delete it(I get the right reference):

FIRDatabase.database().reference().child("posts").child(commentsArray[indexPath.row].key).removeValue()

If I try to po this value the output is e.g:

https://snuspedia.firebaseio.com/posts/coments/-KTzfD1wOa9sRXw93gAF

Which is this:

Am I doing something wrong?

最满意答案

所以我认识到你错过了帖子的关键：

https://snuspedia.firebaseio.com/posts/<KEY OF YOUR POST>/comments/-KTzfD1wOa9sRXw93gAF

参考代码应包含特定帖子的关键字：

FIRDatabase.database().reference().child("posts").child(<KEY OF YOUR POST>).child("comments").child(commentsArray[indexPath.row].key).removeValue()

So what I recognize is that you miss the key of the post:

https://snuspedia.firebaseio.com/posts/<KEY OF YOUR POST>/comments/-KTzfD1wOa9sRXw93gAF

Reference code should include the key of the specific post:

FIRDatabase.database().reference().child("posts").child(<KEY OF YOUR POST>).child("comments").child(commentsArray[indexPath.row].key).removeValue()
