我在烧瓶中有以下模板结构:
templates/
/posts
list.html
base.html
index.html
我的base.html:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>ITV</title>
<!-- Latest compiled and minified CSS -->
<link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css">
<link rel="stylesheet" href="{{ url_for('static', filename='css/main.css') }}">
<!-- Latest compiled and minified JavaScript -->
<script src="//netdna.bootstrapcdn.com/bootstrap/3.1.1/js/bootstrap.min.js"></script>
</head>
<body>
{%- block topbar -%}
<nav class="navbar navbar-default navbar-static-top" role="navigation">
<!-- We use the fluid option here to avoid overriding the fixed width of a normal container within the narrow content columns. -->
<div class="container-fluid">
<div class="navbar-header">
<a class="navbar-brand" href="/">????</a>
</div>
<!-- Collect the nav links, forms, and other content for toggling -->
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-8">
<ul class="nav navbar-nav">
<li class="active"><a href="/">???????</a></li>
<li><a href="/posts">??????</a></li>
<li><a href="/schedue">??????? ??????</a></li>
</ul>
</div><!-- /.navbar-collapse -->
</div>
</nav>
{%- endblock -%}
<div class="container">
<div class="content">
{% block page_header %}{% endblock %}
{% block content %}{% endblock %}
</div>
</div>
</body>
</html>
我可以渲染模板,例如:render_template('posts/list.html'),它扩展了我的base.html
我的list.html:
{% extends "base.html" %}
{% block content %}
Posts
{% endblock %}
如何在base.html中设置活动元素菜单
<li class="active"><a href="/">???????</a></li>
<li><a href="/posts">??????</a></li>
<li><a href="/schedue">??????? ??????</a></li>
当我渲染list.html,并且无法将数据直接传递到base.html？

在Flask中,默认情况下,request变量在模板中可用,因此您只需签request.path入base.html并调整链接即可.
<li {% if request.path == '/' %}class="active"{% endif %}>
<a href="/">???????</a>
</li>
