问题描述
我有一个布局模板和一个子模板.但是，子模板中没有显示其他信息.为什么不使用子模板中的信息?
I have a layout template and a child template. However, none of the extra information from the child template is showing up. Why isn't the information in the child template being used?
FlaskTest.py
FlaskTest.py
from flask import Flask, render_template
app = Flask(__name__)
@app.route('/')
def hello_world():
return render_template('layout.html')
if __name__ == '__main__':
app.run()
layout.html
layout.html
<!doctype html>
<html>
<head>
{% block head %}
<link rel="stylesheet" href="{{ url_for('static', filename='style.css') }}">
<title>{% block title %}{% endblock %} - My Webpage</title>
{% endblock %}
</head>
<body>
<div id="content">{% block content %}{% endblock %}</div>
<div id="footer">
{% block footer %}
© Copyright 2010 by <a href="http://domain.invalid/">you</a>.
{% endblock %}
</div>
</body>
</html>
child.html
child.html
{% extends 'layout.html' %}
{% block title %}Index{% endblock %}
{% block head %}
{{ super() }}
<style type="text/css">
.important {
color: #336699;
}
</style>
{% endblock %}
{% block content %}
<h1>Index</h1>
<p class="important">
Welcome on my awesome homepage.
{% endblock %}
在 http://localhost:5000/上，我得到了:
<!doctype html>
<html>
<head>
<link rel="stylesheet" href="/static/style.css">
<title> - My Webpage</title>
</head>
<body>
<div id="content"></div>
<div id="footer">
© Copyright 2010 by <a href="http://domain.invalid/">you</a>.
</div>
</body>
</html>
推荐答案
您需要呈现child.html，而不是layout.html.子级会扩展布局，但是您编写它的方式只会渲染布局.
You need to render child.html, not layout.html. Child will extend layout, but the way you've written it, only layout will be rendered.
return render_template('child.html')
