Stopping the Inheritance of nav-bar for a particular template - python

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?

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 %}

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.

Extending template using Django doesn't work

I'm having trouble displaying my content with Django in my ecommerce app. This is the base url with only the navigation bar:

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

Python Django Webapp is not responsive in smartphone

I have developed my first web app in python Django framework, deployed in pythonanywhere.com web server.
I have already used the latest bootstrap in this app, but it is not responsive properly on a smartphone screen. responsive in laptop and tablet but not in a smartphone.
You can also check it in your phone "http://sandeepbhatt.pythonanywhere.com/".

I found the solution after number of testing in my app and found there was only one bootstrap tag missing.
I just add this in my base.html file:
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
and now it is proper responsive on every device.

Your template is broken, look at <h5> class-"font-italic there is no closure (in index.html)

Tab showing on homepage which shouldnt show

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')

No CSS and JS, when slash at the end [duplicate]

When I go to
http://127.0.0.1:5000/any_url_not_routed , like below,
it returns a 404 error as expected, but when I put a slash at the end,
http://127.0.0.1:5000/any_url_not_routed/ , like below,
it renders the same page but with no css and js.
Similar thing happens with other pages like /register, /login, etc. Also, browsers put automatic slash at the end.
Please tell me what is happening? I can link more code here.

Your "css/bootstrap.min.css" results in "/css/bootstrap.min.css" when the trailing slash is missing and "/any_url_not_routed/css/bootstrap.min.css" when the trailing slash is present.
You should use the absolute path "/css/bootstrap.min.css" for referencing resources, just as you already do for actions like "/register".
You can check the truth of this by looking at your server's request logs.
