I want to update firebase database with react-CodePudding

I have a problem while trying to update data in the firebase database with my react code. Most probably my code syntax is not good, so can you help me in some way?

This is my code syntax:

const addNewData = async (e) => {


e.preventDefault();

  let data = {
  sifra:sifraRef.current.value,
  naziv:nazivRef.current.value,
  detalji_dijete:detaljiRef.current.value,
  opis:opisRef.current.value,
  broj_obroka:brojObrokaRef.current.value,
  napomena:napomenaRef.current.value
}  
const uuid = uid();
await updateDoc(collection(db, `namirnice/${uuid}`), data)


  close();

  }

All these examples I saw on youtube tutorials works... I hope you can help me.

CodePudding user response：

The updateDoc function is used to update an existing document. But since you call uuid(), you always get a new value and so you're trying to update a document that doesn't exist yet, which isn't possible.

To create a new document, use setDoc instead of updateDoc in your code.

Also see the Firebase documentation on setting a document
