Firebase安全規則，設置孩子不可讀？

Question

所以我有這個數據庫的結構：

在型材我要寄&提供商名稱只爲管理員和 用戶名可讀爲每個登錄的用戶可讀。 我如何實現這一目標？

這裏是我的規則：

{ 
    "rules": 
    { 
    "users": 
    { 
     "$uid": 
     { 
     // grants write access to the owner of this user account whose uid  must exactly match the key ($uid) 
     ".write": "auth !== null && auth.uid === $uid", 
     "profile": 
     { 
      // grants read access only for registered users 
      ".read": "auth !== null", 
      "email": 
      { 
      // This doesn't work with firebase as I was reading doc.      
      ".read": false 
      } 
     } 
     } 
    } 
    } 
}

那麼一點研究後和閱讀去正規化結構我想這樣會工作。事實是，我很想嵌套，但在firebase上可能是一個壞主意。

{ 
     "rules": 
     { 
     "users": 
     { 
      "$uid": 
      { 
      // grants write access to the owner of this user account whose uid must exactly match the key ($uid) 
      ".write": "auth !== null && auth.uid == $uid", 
      "public-profile": 
      { 
       // grants read access only for registered users 
       ".read": "auth !== null" 
      } 
      } 
     }, 
     "private-profile": 
     { 
      "$uid": 
      { 
       ".read": "root.child('users').child(auth.uid).child('role').child('admin').val() === 'true' && root.child('users').child('1').child('role').child('admin').val() === 'true'", 
       ".write": "root.child('users').child(auth.uid).child('role').child('admin').val() === 'true' && root.child('users').child('1').child('role').child('admin').val() === 'true'" 
      } 
     } 
     } 
    }
