Querying “where” clause with document auto-id firebase

Question

I'm currently in a project using Firebase Cloud Firestore and VueJS.

I have this “where” clause, which needs the id of the selected collection. Basically it has to update, where the document id has the this.editSemId. There's some other stuff to the method, but all I need is a way to get the document id from within my collection of semesters in firebase:

Here's how it works: http://recordit.co/Hu67ekLWHv

.collection(“semesters”) .where(“DOCUMENT_ID”, “==”, this.editSemId)

I know how to “get” the document id, which is done with the “this.editSemId”, but I don't know how to get it for the above query

Answer 1

您可以使用FieldPath.documentId（）进行涉及文档ID的查询。

.collection("semesters").where(FieldPath.documentId(), "==", this.editSemId)
