Firestore rules Reference型使用時の注意

Last updated at Posted at 2023-02-14

TL;DR

文字列とReferenceは比較できないので、

function matchUserReference(ref, userId) {
    return ref != null && ref == get(/databases/$(database)/documents/users/$(userId)).__name__;
}

これを使う。

    allow <操作>: if matchUserReference(resource.data.<refのキー>, request.auth.uid);

こう。

postsを保存する時等、userのRefをフィールドとして保存したい。
自分は

    allow <操作>: if '/users/' + request.auth.uid == resource.data.author;

としてしまい、かなりの時間詰まった。

web consoleは使用感がとても悪いのでvscodeで書けるようにした方が良さそう。
