在 jinja 中覆盖块答案

【问题标题】：Overwriting blocks in jinja在 jinja 中覆盖块

【问题描述】：

所以我正在学习 Jinja，并尝试使用扩展功能来用新内容覆盖块，但它不起作用。

home.html

      {% block mainBlock %}
   <div id="newNewsCont">
      <div id="leftCont">
        <h2> Tesla Model 3 </h2>
        <p> Model 3 combines real world range, performance, safety and spaciousness into a premium saloon that only Tesla can build. Our most affordable range yet, Model 3 acheives 215 miles of rage per charge while starting at only 35,000 USD before incentives. Model 3 is designed to attain the highest safety ratings in every category. </p>
      </div>

      <div id="rightCont">
        <h2> Reliant Robin LX 3DR 0.9 </h2>
        <p> 2 keys, cherry bomb exhaust, this car turns heads, just had brand new custom made interior fitted, with sound proofing under carpets, just had a full respray in renault 5 gt turbo pearl white </p>
      </div>
   </div>
  {%endblock%}

我想用 list.html 覆盖它

{% extends "home.html" %}

{% block mainBlock %}
    {% for item in cars %}
        <li> {{ item }}</li>
    {% endfor %}

{%endblock%}

server.py

import os
from flask import Flask, redirect, request, render_template

DATABASE = 'database.db'


app = Flask(__name__)

ALLOWED_EXTENSIONS = set(['txt', 'pdf', 'png', 'jpg', 'jpeg', 'gif'])

@app.route("/")
def home():
return render_template('list.html', msg = '')

@app.route("/ListCars")
def cars():
cars = ['tesla','reliant robin','Transit Van']
return render_template('list.html', cars = cars)

if __name__ == "__main__":
app.run(debug=True)

【问题讨论】：

“不工作”到底是什么意思？你可以看看 Jinja2 继承部分jinja.pocoo.org/docs/dev/templates/#template-inheritance
哦，我已经阅读了很多次该页面，但它对我来说毫无意义。我希望 list.html 中 mainblock 的内容覆盖 home.html 中 mainblock 的内容
加载list.html的结果是什么？

标签： html ajax flask jinja2

【解决方案1】：

如果您想为list.html 保留home.html 设计：

list.html

{% block mainBlock %}
{{super()}}
...
{%endblock%}

如果这不是你想要的，那么写出确切的问题，因为你的代码很好应该可以工作。
