What is extends in Django? How to create standard template design in Django

 


It is used to provide the extendibility of parent template or base template to child template.

If we want to create a master-child template in the Django application then we use extends operation in Django.

Child pages inherit the complete functionality of the base template.


Syntax of base template or master template

<html>

<head>

</head>

<body>

<div id="container">

<header>

</header>

<section>

{% block blockame %}
    Content Place Holder
  {% endblock %}

</section>

<footer>

</footer>

</div>


</body>

</html>


Syntax of child page:-

{% extends 'appname/parentpage.html' %}

{% block blockname %}
    hello
{% endblock %}



Now I am providing the code of the base.html or master.html file:-

<!DOCTYPE html>

<html>

<head>

<title></title>

<link rel="stylesheet" type="text/css" href="/static/style.css">

</head>

<body>

<header>

<ul>

<li><a href="/userapp">Home</a></li>

   <li><a href="about">About us</a></li>

   <li><a href="contact">Contact us</a></li>

   <li><a href="services">Services</a></li>

   <li><a href="gallery">Gallery</a></li>

</ul>

  Uncontrolled form input in React-JS? If we want to take input from users without any separate event handling then we can uncontrolled the data binding technique. The uncontrolled input is similar to the traditional HTML form inputs. The DOM itself handles the form data. Here, the HTML elements maintain their own state that will be updated when the input value changes. To write an uncontrolled component, you need to use a ref to get form values from the DOM. In other words, there is no need to write an event handler for every state update. You can use a ref to access the input field value of the form from the DOM. Example of Uncontrolled Form Input:- import React from "react" ; export class Info extends React . Component {     constructor ( props )     {         super ( props );         this . fun = this . fun . bind ( this ); //event method binding         this . input = React . createRef ();...
