I am updating a document in firebase when user enters a comment.The code for the same is:
const docRef=collection(db,"posts",post.id);
console.log(docRef);
updateDoc(docRef,{
user:localStorage.getItem('Name'),
title: post.title,
comment:temppost ,
upVotesCount: 0,
downVotesCount: 0,
createdAt: post.createdAt,
updatedAt: date.toUTCString(),
isCommentVisible:false
});
But I m getting this error:
Uncaught (in promise) FirebaseError: Invalid collection reference. Collection references must have an odd number of segments, but posts/PQAvoGjUeX8aPVVZxMNC has 2.
I haven't used any subcollections here.
You need a DocumentReference to update a single document that you can create using doc(). The collection() is used to create a CollectionReference:
// use doc() instead of collection()
const docRef = doc(db,"posts",post.id);
Also checkout: Firestore: What's the pattern for adding new data in Web v9?
You are trying to pass a document in a collection function. (db,"posts") is how you refer to a collection and (db,"posts",post.id) is how you refer to a document. So use one of these:
const docRef = doc(db,"posts",post.id); // 3 arguments for a document
------
const postsRef = collection(db,"posts"); // 2 arguments for a collection
const docRef = (postsRef,post.id); // in essence 2+1 arguments for a document
