typeorm 保存列表为字符串

Question

我有一个 flutter 前端，它在 ['url'、'url'、'url'] 之类的列表中发送 url 个字符串，但在 Postgres 中它是 saved/on检索显示为单个字符串，如 'url,url,url'.

这是有问题的列：

  @Column({
    type: "simple-array",
    default: [],
  })
  postMedia!: string[];

这是保存 post 的存储库方法：

  async addPost(req: Request, res: Response) {
    let { email } = req.params;
    let postText = req.body.postText;
    let postMedia: string[] = req.body.postMedia;

    let accountRepo = getCustomRepository(AccountRepository);
    let account = await accountRepo.findOne({
      email: email,
    });

    try {
      let post = new PostEntity();
      post.postText = postText;
      post.postMedia = postMedia;
      post.account = account!;
      await post.save();

      return res.send({
        message: "Post Added",
        added: true,
      });
    } catch (error) {
      console.log(error);
      return res.send({
        message: "Something went wrong",
        added: false,
      });
    }
  }

问题出在哪里？为什么即使我将 postMedia 变量键入为 string[]，列表仍未保存为数组？请帮忙

这对我有用

@Column("text", { array: true })
postMedia!: string[];
