I'm trying to get document references from the fetched documents of the collection "products" with 2 sets of code below but both return "undefined".
Get single document:
const docsSnap = await getDoc(
doc(db, "products/WuAC97j0avTAFNs1kvdf"),
);
console.log(docsSnap.data().ref); // undefined
Get multiple documents:
const docsSnap = await getDocs(
collection(db, "products"),
);
console.log(docsSnap.docs[0].data().ref); // undefined
Are there any ways to get document references from the fetched documents?
Remove ".data()" before ".ref" from both of the code to get document references.
Get single document:
const docsSnap = await getDoc(
doc(db, "products/WuAC97j0avTAFNs1kvdf"),
);
// Here
console.log(docsSnap.ref); // Tc
Get multiple documents:
const docsSnap = await getDocs(
collection(db, "products"),
);
// Here
console.log(docsSnap.docs[0].ref); // Tc
In addition, you can also get document IDs by replacing ".ref" with ".id":
Get single document:
const docsSnap = await getDoc(
doc(db, "products/WuAC97j0avTAFNs1kvdf"),
);
// Here
console.log(docsSnap.id); // WuAC97j0avTAFNs1kvdf
Get multiple documents:
const docsSnap = await getDocs(
collection(db, "products"),
);
// Here
console.log(docsSnap.docs[0].id); // WuAC97j0avTAFNs1kvdf
