在Firestore中删除数组中的索引 [英] Delete index at array in Firestore
问题描述
我在文档中得到了这些数据:
I got this data in my document:
我要删除索引0.我该怎么做?这应该可以实现我认为的窍门:
I want to delete index 0. How do I do this? This should do the trick I thought:
db.collection("data").document("free").updateData(["deleteme.deletemee.0" : FieldValue.delete()]) { (errr) in
print(errr)
}
但是errr打印nil,并且什么也没有删除.在获取文档时,使用以下代码时,我发现数据有些奇怪:
But the errr prints nil, and nothing is removed. When getting the document I noticed something strange about the data when using this code:
db.collection("data").document("free").getDocument { (doc, err) in
guard let _doc = doc,
doc?.exists ?? false else{ return }
print(_doc.data())
}
打印输出:
["deleteme": {
deletemee = (
1 //this is the value for the key, but where is my key?! :(
);
}]
我看不到钥匙,它在哪里?如何在Firestore的索引处删除某些内容?谢谢.
I cannot see the key, where is it? How to delete something at an index in Firestore? Thanks.
推荐答案
终于支持了数组操作.现在,通过值(而不是索引)支持删除,添加等:
Array operations have finally been supported. Deletion, addition, etc. are supported via the value (not the index) now:
At the moment, there are a few bugs at the moment though as this one I encountered.
