Question

每当我使用 'createOrReplace' 理智地创建一个新文档时。它成功创建了文档，但是它没有在主屏幕上显示新创建的文档。

注意：我从 Sanity Studio 上传的所有其他文档都正确显示。只有使用 'createOrReplace' 创建的未显示

如果你想查看，这是我的代码：

Home.js

import Post from '../components/Post.component';

const Home = ({ navigation }) => {

  const [posts, setPosts] = useState([]);

    useEffect(() => {
        querySelector();
    })

  const querySelector = async () => {
      const query = `*[_type == 'post']`
      const post = await client.fetch(query);

      setPosts(post);
  }

  return (
      <>
      /* <CustomHeader screenName="Home" back={false} height={150} />
