How to create new document reference for runTransaction in react (firebase)?-CodePudding

I want to create a new doc in firebase/firestore, in runTransaction function of firebase in react. But I don't know how to create a reference for new doc in react firebase?

import { useEffect, useState } from "react";
import "../../css/centerLoader.css";
import { MainFlexLoader } from "../CenterLoader";

import { auth } from "../../firebase-config";
import { db } from "../../firebase-config";

import { collection, doc, runTransaction } from "firebase/firestore";

export default function Records() {
  const [isLoading, setIsLoading] = useState(true);
  const [total, setTotal] = useState(0);

  const initailizeData = async () => {
    setIsLoading(true);
    try {
      // here I want to add new document with transaction
      await runTransaction(db, async (transaction) => {
        let newRecordRef = collection(db, "users", auth.currentUser.uid, "record",);
        transaction.set(newRecordRef, {
          amount: 1000,
        });
      });
    } catch (err) {
      alert(err);
    } finally {
      setIsLoading(false);
    }
  };

  useEffect(() => {
    initailizeData();
  }, []);

  if (isLoading) return <MainFlexLoader />;

  return <div className="main"></div>;
}

CodePudding user response：

If you are trying to add a document with a random ID then try:

const newRecordRef = doc(collection(db, "users", auth.currentUser.uid, "record"));

If you want to specify your own ID, then use doc() itself:

const newRecordRef = doc(db, "users", auth.currentUser.uid, "record", "custom-record-id"));
