As you can see I'm doing a check if the user is anonymous if he is not anonymous it should show the log out button. But at the moment when I return to the homepage it still shows the Log Out button.
My question is, how do I make it so that the log out will not show on the homepage. According to my own thinking I think django still thinks I'm not anonymous on the homepage.
And this is the image for the problem:
homepage

You should be using is_authenticated instead:
{% if user.is_authenticated %}
<li>Log Out</li>
{% endif %}
And, you are not passing the request context from your view to a template, use render():
return render(request, 'index.html')

I have tried many times to modify the index.html to be able to extent by the base.html but failed.
Neither only the background color change nor the jquery cannot be load in the chrome, as a result no datetimepicker is appear.
How can I use the {% extends "base.html" %} (jinja2 method) to extend the base.html to index.html?
Thanks very much
First of all you have to define
{% block content %}{% endblock %}
in base.html and then in the index.html.
{% extends "base.html" %} // at top of file
All the content should be between
{% block content %}{% endblock %} in index.html. you can see in documentation
base.html
<html> ...
your_main_html.html
{% extends "base.html" %}
{% block extrahead %}
<style>
<!-- your css codes -->
</style>
{% endblock %}
{% block content %}
<!-- your html and jinja codes -->
{% endblock %}
{% block extrajs %}
<script>
<!-- your js codes -->
</script>
{% endblock %}
you will need to download jQuery js file from https://jquery.com/download/ and use it in your index file inside head tag as
<script src="jquery-3.6.1.min.js"></script>
or
use jQuery CDN as below
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.1/jquery.min.js"></script>

{% block js %}
<script src="{% static 'js/quicky/navbar.js' %}"></script>
{% endblock %}
And this is the navbar.js file placed in static folder.
$(function () {
'use strict'
$('[data-toggle="offcanvas"]').on('click', function () {
$('.offcanvas-collapse').toggleClass('open')
})
})
In the console I am getting this error.
Uncaught ReferenceError: $ is not defined.
I believe this error occurs because the navbar.js file, for some reason is not able to have the jquery. But if you see the Base.html file I first loaded the bootstrap files and then I placed the {% block js %}. So that first the jquery gets loaded and then my navbar.js file would come.
Also if I remove those block elements and write the contents of navbar.js file directly in Base.html I do not get this error.
What is the problem with the {% block js %}?
You are loading the static files including a function which requires jquery before you actually load the jquery library. This is why you are getting the error $ is not defined since $ is defined/instantiated in jquery
Try this - manually add the navbar.js to your index.html page after the jquery library and confirm that the error goes away. If it does, then it means your issue is with your load sequence.
The template included by an include tag is independent (except perhaps with regards to the context) of the including template. From the documentation:
The
include
tag should be considered as an implementation of “render this
subtemplate and include the HTML”, not as “parse this subtemplate and
include its contents as if it were part of the parent”. This means
that there is no shared state between included templates – each
include is a completely independent rendering process.
That is the blocks of the including template or the blocks of the templates which extend the including template are not at all related to the included template.
You should simply render that script tag (and any other things that you expect to be filled in the parent blocks templates) separately in your base template:
<script src="{% static 'js/quicky/navbar.js' %}"></script>
{% block js %}{% endblock %}
Or if you want to be able to remove this tag by extending the template:
<!-- in base template -->
{% block js %}
<script src="{% static 'js/quicky/navbar.js' %}"></script>
{% endblock %}
<!-- in children templates keeping the navbar js -->
{% block js %}
{{ block.super }}
<script src="{% static 'js/someother.js' %}"></script>
{% endblock %}
<!-- in children templates NOT keeping the navbar js -->
{% block js %}
<!-- Since we dont render block.super it is not rendered anymore -->
<script src="{% static 'js/someother.js' %}"></script>
{% endblock %}

When i extend base.html into home.html, i'm facing some identation problem and getting wrong output.
This is how home.html looks like after extending base.html:
{% extends "blog/base.html" %} {% block content %} {% for post in posts %}
<article class="media content-section">
<div class="media-body">
<div class="article-metadata">
<a class="mr-2" href="#">{{ post.author }}</a>
<small class="text-muted">{{ post.date_posted }}</small>
</div>
<h2><a class="article-title" href="#">{{ post.title }}</a></h2>
<p class="article-content">{{ post.content }}</p>
</div>
</article>
{% endfor %} {% endblock content %}
Why i'm getting this.Is there any auto identation feature in visual studio code?
I believe you must match the amount of indentation exactly the same where the blocks are occupied. Say that your blocks are situated on the fourth tab indent, the new code must also be situated starting from the fourth indent.
Although the truth is, HTML indents don't matter -- as long as you have matching tags, you might as well as to put everything in one line and the HTML will still function. Having used python myself, it's hard to believe that indentation doesn't matter, but once you touched languages like c++ or java, you'll see that the indentation rule isn't global.
Answering your other question, I believe you can use some auto-indention as described here, but I don't see that necessary in HTML as very few people will see your web source code.
Also as a quick tip, it's a better practice to use two-space indents rather than four in HTML. In your first code block, it's obvious that most of the code in the middle is outside the frame, and that's caused by the numerous levels before it.

As you can see, I have the {% block content %} tag so I can extend this website with the homepage. This is home.html:
{% extends 'store/store.html' %}
<h1>HelloWorld</h1>
The issue is that I cannot see "HelloWorld", only the navigation bar from the base html. Any help will be appreciated!
You need to put your content in a block that is defined in the template you are extending for it to render. In this case the content block
{% extends 'store/store.html' %}
{% block content %}
<h1>HelloWorld</h1>
{% endblock content %}
The blocks in the "parent" template define the sections where you can insert content in an extending template, you need to use {% block %} in the extending template to tell the renderer which section you are placing content into. Anything outside of a {% block %} will not be rendered

Stopping the Inheritance of nav-bar for a particular template

I working on a Django project and there is a navbar for the site. So when one user gets logged in I want to change the navbar. So how can I stop the navbar getting inherited from the base template?

</ul>
</div><!-- /.navbar-collapse -->
</div><!-- /.container-fluid -->
</nav>
{% block content %}
{% endblock content%}
</div>
</body>
</html>
This is my base.html looks like and , please give me an idea about how the new template look like? Thank You
you can user django template tags e.g this is template tags which display that if user is authenticated then it will show logout button else login. same way you can do it for your navigation bar in base.html.
{% if request.user.is_authenticated %}
<li>Log Out</li>
{% else %}
<li>Log In</li>
{% endif %}
