write 모듈에서 포스트 수정을 위한 코드를 작성한 후에는 WriteActionButtonsContainer와 WriteActionButtons 컴포넌트를 차례로 수정해 주세요.

containers/write/WriteActionButtonsContainer.js

import React, { useEffect } from 'react';
import WriteActionButtons from '../../components/write/WriteActionButtons';
import { useSelector, useDispatch } from 'react-redux';
import { withRouter } from 'react-router-dom';
import { writePost, updatePost } from '../../modules/write';

const WriteActionButtonsContainer = ({ history }) => {
  const dispatch = useDispatch();
  const { title, body, tags, post, postError, originalPostId } = useSelector(
    ({ write }) => ({
      title: write.title,
      body: write.body,
      tags: write.tags,
      post: write.post,
      postError: write.postError,
      originalPostId: write.originalPostId,
    }),
  );

  // 포스트 등록
  const onPublish = () => {
    if (originalPostId) {
      dispatch(updatePost({ title, body, tags, id: originalPostId }));
      return;
    }
    dispatch(
      writePost({
        title,
        body,
        tags,
      }),
    );
  };

  (...)
  return (
    <WriteActionButtons
      onPublish={onPublish}
      onCancel={onCancel}
      isEdit={!!originalPostId}
    />
  );
};

export default withRouter(WriteActionButtonsContainer);
