【问题描述】：

使用 Lektor，我创建了一个模型 book 作为 books 模型的子模型（类似于 blog-post 和 blog 模型）。

/books/ 页面正在正确生成，底部有分页。当我转到第二页时，它抛出了这个奇怪的错误。

Build Failure :'(

Building of the artifact “books/page/2/index.html” failed. This is what we know about the problem:

TemplateSyntaxError: Encountered unknown tag 'endblock'.

这是books.html

{% extends "base.html" %}

{% from "macros/pagination.html" import render_pagination %}

{% block title %}Books{% endblock %}


{% block content %}

    <ul class="blog-index">
        {% for post in this.pagination.items %}
            <h2>
                <a href="{{ post|url }}">
                    {{ post.title }}
                </a>
            </h2>
        {% endfor %}
    </ul>

    <div style="padding-left: 45px;">
        {% if this.pagination.pages > 1 %}
            {{ render_pagination(this.pagination) }}
        {% endif %}
    </div>
{% endblock %}

如回溯中所示，我在 books.html 的第 13 行中没有 {% endblock %}。

【问题讨论】：

第 13 行包含 {{ post|url }}。 |url 过滤器应该做什么？我在标准 Jinja 模板过滤器列表中找不到它。
是base.html中派生的错误吗？如果你还没有，我会检查所有的块是否都在那里关闭。
@JohnGordon url 过滤器由 lektor 分页添加
@wgwz 不，它不是从 base.html 派生的，因为所有块都已正确关闭

【解决方案1】：

如果您使用的是 Lektor 1（当前发布的版本），语法错误有时会很遗憾地被缓存。清除 lektor 缓存以查看是否可以解决问题（您可以使用 lektor clean 来解决此问题。
