Question

当前，我正在尝试将form.html扩展为layout.html（具有模板）。我尝试利用{％extended“ layout.html”％}并使用{％block main％}和{％endblock％}。但是，这似乎不起作用。当我进入layout.html时，它将具有一个导航栏，其中包括：首页，表单，表格。但是，当我单击表单页面时，找不到404页面。有什么问题吗？

            {% endblock %}
        </main>

    </body>

</html>

THIS IS FOR form.html
{% extends "layout.html" %}

{% block main %}

    <!-- http://getbootstrap.com/docs/4.1/content/typography/ -->
    <h1 class="mb-3">Form</h1>

    <!-- http://getbootstrap.com/docs/4.1/components/forms/ -->
    <form action="/form" method="post">

        <!-- TODO -->

        <!-- http://getbootstrap.com/docs/4.1/components/buttons/ -->
        <button class="btn btn-primary" type="submit">Submit</button>

    </form>

    <script>

        /* TODO */

    </script>

{% endblock %}

在终端内部，我期望使用layout.html模板呈现form.html页面。但是，我得到了 [2019-07-13T06：02：11.139Z]“获取/窗体”错误（404）：“未找到”

HTML扩展找不到模板404
