firebase - Firestore 权限缺失或不足

Question

我收到错误:Firebase 缺少或权限不足

代码: const demoCollectionRef = this.db.collection('items'); 返回 demoCollectionRef.add(item);

我认为这个错误是因为angularfire2的.add方法。

Firestore 规则:

function isAuthenticated() {
  return request.auth.uid != null;
}

function isAdmin() {
    return request.auth.token.admin == true;
}

allow create: if isAuthenticated();
allow update, delete: if isAdmin(); // .add method checks update rules 
// at the place of checking the create rules, which make it send error.

但是如果我将更新规则更改为:允许更新、删除:if isAuthenticated();它工作正常
