在我刷新页面之前，表格数据不会更新

Question

我遇到的问题是，当我通过模态组件向数据库添加数据时，新数据不会立即出现在表中。它只有在我刷新页面后才会显示。我尝试实现刷新键逻辑来重新获取组件，但它不起作用。我希望新数据在通过模式添加后立即反映在表中，而不需要手动刷新。数据表组件是我调用模态和表格的地方。

您正在使用 setArtists 更新状态并增加刷新键，但刷新键没有正确触发重新获取。

试试这个：

import React, { useState, useEffect } from "react";
import ReviewFeature from "./ReviewFeature";
import ArtistModal from "./ArtistModal";
import Dropdown from "./Dropdown";
import Layout from "../../Components/Layout";
import { fetchReviewArtist, searchArtist } from "../../Services/Api";

const ReviewDataTable = () => {
  const [modalIsOpen, setModalIsOpen] = useState(false);
  const [dropdownVisible, setDropdownVisible] = useState(false);
  const [searchTerm, setSearchTerm] = useState("");
  const [filteredItems, setFilteredItems] = useState([]);
  const [artists, setArtists] = useState([]);

  useEffect(() => {
    const fetchArtists = async () => {
      try {
        const response = await fetchReviewArtist();
        console.log("Fetched artists:", response);
        setArtists(response);
      } catch (error) {
        console.error("Error fetching artists:", error);
      }
    };

    fetchArtists();
  }, []); // Only run on mount

  const fetchSpotifyArtists = async (query) => {
    try {
      const artists = await searchArtist(query);
      console.log("artists:", artists);
      setFilteredItems(artists);
    } catch (error) {
      console.error("Error fetching Spotify artists:", error);
      setFilteredItems([]);
    }
  };

  const [formData, setFormData] = useState({
    name: "",
    photo: "",
    location: "",
    bio: "",
    genre: " ",
    platforms: "",
    age: "",
    spotifyId: "",
  });

  useEffect(() => {
    if (searchTerm) {
      fetchSpotifyArtists(searchTerm);
    } else {
      setFilteredItems([]);
    }
  }, [searchTerm]);

  const handleSelectArtist = async (artist) => {
    const { name, photo, spotifyId } = artist;
    const artistImage = artist.image || "path/to/default/image.jpg";
    const artistGenres = "Unknown genre";

    const newFormData = {
      name,
      photo: artistImage,
      location: "",
      bio: "",
      genre: artistGenres,
      platforms: "",
      age: "",
      spotifyId: spotifyId,
    };

    setFormData(newFormData);
    setDropdownVisible(false);
    setModalIsOpen(true);
  };

  const openModal = () => {
    setModalIsOpen(true);
  };

  const closeModal = () => {
    setModalIsOpen(false);
  };

  const addArtist = (newArtist) => {
    setArtists((prevArtists) => [...prevArtists, newArtist]);
    closeModal();

  const deleteArtist = (name) => {
    setArtists((prevArtists) =>
