Question

所以我正在学习Jinja，并且我正在尝试使用扩展功能来覆盖具有新内容的块，但它无效。

home.html的

      {% 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)

Answer 1

如果您想保留home.html的{{1}}设计：

list.html

list.html

如果这不是您想要的，那么请写出确切的问题，因为您的代码可以正常工作。
