IT技术 - 更新 React Firestore 中嵌套数组中对象的值 - 吾爱随笔录

我需要在 Firebase 数组中的特定索引处更新对象中的值字段

我试图通过getState()所有对象抓取数组；
然后获取我需要的对象索引；
然后为对象分配新值，在本例中为内容；
然后将整个数组 ( comments)重写为 newArray ( actualComments)，如下所示。

这是我想要的，但只是第一次。如果我再次尝试这样做，我会收到错误消息TypeError: "content" is read-only。

    export const editComment = (comment) => {
      return (dispatch, getState, { getFirebase, getFirestore }) => {
        const firestore = getFirestore();

        let actualComments = getState().firestore.data.topics[comment.topicId].comments;
        let numberArray = actualComments.findIndex(e => {return e.id === comment.commentId});
        actualComments[numberArray].content = comment.editContent;

        firestore.collection('topics').doc(comment.topicId).update({     
          comments: actualComments
        }).then(() => {
          dispatch({ type: 'EDIT_COMMENT' })
        }).catch((error) => {
          dispatch({ type: 'EDIT_COMMENT_ERROR', error})
        })
      }
    }

/////Grab through reference all comments Array in firestore let actualComments = getState().firestore.data.topics[comment.topicId].comments; ////make container for array let updatedComments = []; //// copy array from reference to empty updatedComments array actualComments.forEach(comment => { updatedComments.push({ content: comment.content, createdAt: comment.createdAt, editDate: comment.editDate, edited: comment.edited, id: comment.id, idTopic: comment.idTopic, name: comment.name, nameId: comment.nameId }) }) //// grab index which i want to update let numberArray = actualComments.findIndex(e => {return e.id === comment.commentId}); //// update in specific index array updatedComments[numberArray].content = comment.editContent; updatedComments[numberArray].editDate = new Date(); updatedComments[numberArray].edited = true; //// replace updated array in firestore firestore.collection('topics').doc(comment.topicId).update({ comments: updatedComments }).then...
