Как я могу получить тот же объект в области посетителя, что и в области администратора без пользователя $ uid

Question

В настоящее время на веб-сайте блога, как будто у меня возникла проблема, которую я не ожидал, когда начну ее создавать ...

Я создаю ее так:

• Область администратора, где вынеобходимо войти в систему, где вы можете писать / удалять статьи.

• Публичная область, где вам не нужно входить в систему, где вы можете увидеть статьи, пишущие в административной области.

Моя база данныхпостроить как показано ниже, как вы видите, каждый пользователь получил $ uid.Поэтому из-за того, как он построен, мой сервис выглядит следующим образом:

}

Поэтому, когда я звоню в службу для получения моих статей в административной области, я получаю и в общедоступной области я получаю .

Я нахожу способ получить значение, но таким образом я теряю ключевой объект.

export interface Article {
    name: string,
    author: string,
    category: string[],
    content: string,
    date: string,
    image: string,
    key: string,
    $exists: () => boolean
  }

Как я могу получить тот же объект в области посетителя, что и я?в админке?
