使用火力orderByChild反应中母语与终极版时未指定警告

问题描述 投票:0回答:1

在我反应过来,本地项目添加orderByChild火力过滤器时,即使该应用程序是阅读和筛选数据精我得到一个神秘的黄箱错误。

如果删除orderByChild一切工作正常。

代码给予警告:

export const peopleFetchAll = ({ name }) => {
console.log(`${name}`);

return (dispatch) => {
  firebase.database().ref(`/people`).orderByChild("name").equalTo("Paul")
    .once('value', snapshot => {
        dispatch({ type:PEOPLE_FETCH_SUCCESS, payload:snapshot.val() });
    });
  };
};

良好的代码:

export const peopleFetchAll = ({ name }) => {
console.log(`${name}`);

return (dispatch) => {
  firebase.database().ref(`/people`)
    .once('value', snapshot => {
        dispatch({ type:PEOPLE_FETCH_SUCCESS, payload:snapshot.val() });
    });
  };
};

我在世博园看到的错误是:

再次,一切工作正常,即使我得到警告。我只需要摆脱的警告,我似乎无法破译此。

你定义的下name /people指数,如下所示:firebase.google.com/docs/database/security/indexing-data?

如果不是,这可能是为警告的原因,但我不明白为什么它不会显示实际的警告信息。
