ViewsProblem with request from Subcollection in Firestore
Hey I try to fix a Problem I need to get a subcollection based on a query before.
const kurzRef = collectionGroup(db, 'kurzwaffensub' );
const FirstOperation = query(kurzRef,where("kurzModell", "==", `${kurzModell}` ));
const getWaffenDaten = async () => {
const modell = await getDocs(FirstOperation);
const data = [];
for (const doc of modell.docs) {
const parentDoc = await getDoc(doc.ref.parent.parent);
const { Name, avatarPath } = parentDoc.data();
// Thats the code snippet which I have my problem with
const waffenbilderRef = collection(db, 'users', doc.data().uid, 'waffenbildersub')
let subCollectionDocs = await getDocs(waffenbilderRef)
//
data.push({
...doc.data(),
Name,
subCollectionDocs,
avatarPath
});
The documents which I get with the first operation have a String Fieldvalue of the document ID
After that I need to get the subcollection based on the Fieldvalue document ID
Which is one of 3 subcollections which you can see in the picture.
Unfortunately I get something back which I dont fully understand
As you can see I get the subCollectionDocs, but it doesn't display the Data.
You can see next to the RED marked Arrow that there are 2 Documents in the result of the subcollectionDocs. This is right but I don't know how to retrieve the data properly.

You're adding the full DocumentSnapshot from the subcollection query to your state, which is what then shows when you console.log it.
My guess is that you're expecting to just see the document's data and ID, which you can do with:
const subCollectionDocs = await getDocs(waffenbilderRef)
const subCollectionData = subCollectionDocs.docs.map((doc) => {
return { id: doc.id, ...doc.data() };
}
console.log(subCollectionData);
data.push({
...doc.data(),
Name,
subCollectionData,
avatarPath
});
