Steps for updating information in Firebase version 9

How can I add a new record and also change the 'bill' value, but I'm not sure what to input in this string?

const newPostKey = (child(ref(db), )).key;

This is the Vuex action I am using to make a request to Firebase:

async updateInfo({ dispatch, commit, getters }, toUpdate) {
  try {
    const uid = await dispatch('getUid')
    const db = getDatabase();
    const updateData = { ...getters.info, ...toUpdate }
    const postListRef = ref(db, `/users/${uid}/info`);
    const newPostKey = (child(ref(db), ????)).key;
    const updates = {};
    updates[newPostKey] = updateData;
    update(postListRef, updates)
    commit('setInfo', updateData)

  } catch (e) {
    commit('setError', e)
    throw e
  }
},

The code works fine up to the step where const newPostKey is declared.

If I input 'info' in this string:

const newPostKey = (child(ref(db), 'info')).key;

The record will be added, but the 'info' will be updated incorrectly: https://i.sstatic.net/Vn1C6.png

Answer №1

To simply update the value of bill, you can implement the following:

const userReference = ref(db, `/users/${userId}/details`);

update(userReference, { bill: 150 }).then(() => { // change 150 to your desired bill amount
  console.log("Bill Updated Successfully")
}).catch(error => console.log(error))

If you wish to increment the bill by a specific amount, you can utilize the increment() function.

update(userReference, { bill: increment(150) }) // increment by 150
