你可能会以错误的方式考虑布局。布局是模板中最通用的模板，而不是最复杂的模板。如果你只需要很少的独立功能，则按原样以及include在需要的地方编写它们。
也就是说，如果你想要这样的话：
---------------------------------- +--------------+ Header | Login | +--------------+---------------------------------- Body Content (Blog)
而且你还想要一个独立的登录页面，如下所示：
---------------------------------- Header---------------------------------- +--------------+ | Login | +--------------+
然后include在需要的地方创建一个登录部分。
例
模板/部分/login.html
<form action="/login" method="post"><!-- Your login goes here --></form>
templates / your_base.html
<!DOCTYPE html><html><head>{% block head %}{# Default HEAD content goes here with extra nested blocks for children to override if needed. #}{% endblock head %}</head><body><header>{% block header %}{% endblock header %}</header>{# Note: This assumes we *always* want a header #}{% block content %}{% endblock content %}</body></html>templates / login.html
{% extends "your_base.html" -%}{% block content -%}{% include "partials/login.html" %}{%- endblock content %}templates / blog.html
{% extends "your_base.html" -%}{% block header -%}{{ super() }}{# Render the default header contents here #}{% include "partials/login.html" %}{%- endblock header %}{% block content -%}{# Render your blog posts here #}{%- endblock content %}
