How can I order the documents in Firestore? It looks like Firestore lists documents in alphabetic order by the ID I let Firestore automatically create. But I don't want that. I just want to see my newly added document added as the last document in the collection. How do I do that? Should I create my own alphabetic ID's?

我在Firestore中的收藏示例:

推荐答案

Firestore旨在进行大规模扩展.在这种规模下，文档在控制台中的显示顺序无关紧要，因为控制台对于查看集合中的大量文档毫无用处.

Firestore is meant to scale massively. At that scale, it doesn't matter what order the documents appear in the console, because the console is useless for viewing massive numbers of documents within a collection.

如果您仍需要在控制台中订购，则必须提供自己的文档ID.

If you still need an ordering in the console, you will have to come up with document IDs of your own.
