004 Reuse block of HTML in Django

Keep parts of html same on all pages in Django. Reuse block of HTML in Django.

templates > app_ name > base.html

  • Create base.html under templates > app_name
  • Add the following code wherever other html content will come
<!DOCTYPE html><html>    <head>        <meta charset="utf-8">        <title></title>        <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css">    </head>    <body>
        <nav class="navbar navbar-expand-lg navbar-light bg-light">          <a class="navbar-brand" href="#">Navbar</a>          <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">            <span class="navbar-toggler-icon"></span>          </button>          <div class="collapse navbar-collapse" id="navbarSupportedContent">            <ul class="navbar-nav mr-auto">              <li class="nav-item active">                <a class="nav-link" href="#">Home<span class="sr-only">(current)</span></a>              </li>
            </ul>
          </div>        </nav>        <div class="container">            {% block body_block %}
                <!-- Anything outside of this will be inherited if you extend -->            {% endblock %}
        </div>    </body></html>
  • And then in the other html use the following:
<!DOCTYPE html>{% extends "mainApp/base.html" %}
    {% block body_block %}
        <!-- Rest of HTML -->    {% endblock %}
  • This will display the same navbar in all pages where extends "app_name/base.html" is used.
  • It will also use the same header
  • And that is how you can use part of template without rewriting in each html file.

Difference between .exec() and .execPopulate() in Mongoose?

Here I answer what is the difference between .exec() and .execPopulate() in Mongoose? .exec() is used with a query while .execPopulate() is used with a document Syntax for .exec() is as follows: Model.query() . populate ( 'field' ) . exec () // returns promise . then ( function ( document ) { console . log ( document ); }); Syntax for .execPopulate() is as follows: fetchedDocument . populate ( 'field' ) . execPopulate () // returns promise . then ( function ( document ) { console . log ( document ); }); When working with individual document use .execPopulate(), for model query use .exec(). Both returns a promise. One can do without .exec() or .execPopulate() but then has to pass a callback in populate.

Resolve: Uncaught TypeError: firebase.database is not a function

If you are getting the error: Uncaught TypeError: firebase.database is not a function Resolve it by including firebase-database.js in your html page as follows: <!-- The core Firebase JS SDK is always required and must be listed first --> <script defer src = "https://www.gstatic.com/firebasejs/6.2.4/firebase-app.js" ></script> <script defer src = "https://www.gstatic.com/firebasejs/3.1.0/firebase-database.js" ></script> That is it. Let me know if this was helpful.
