我正试图在flask_admin仪表板中查看所有表（烧瓶应用程序）的视图，但我没有在flask_admin中获取任何表。我不知道怎么了。一切似乎都正确。我会尝试其他方式，但仍然停留在这里吗？

我没有收到任何错误。我的flask_admin仪表板有问题。

admin / index.html：

{% extends 'admin/master.html' %}
{% if 'user_name' in session %}
    {{ super() }}
    {% block messages %}
        <h1>Hi,there.</h1>
    {% endblock messages %}
{% endif %}

请帮忙弄清楚！
