Django - check if user is authenticated for every url

On my html, I can check if the user is logged in by using the following syntax:

{% if user.is_authenticated %}
  <div id="display_something">...</div>
{% else %}
  <p>Please Log in</p>
{% endif %}

But what should I do if I want to check if the user is authenticated for every html file I am rendering? Do I have to copy and paste that {% if ... %} block for every single html file? What is the Django's way of handling this issue? What's the good practice?

You shouldn't handle the authentication logic in the template (for the entire site), instead you can use the login_required decorator on your views.

from django.contrib.auth.decorators import login_required

@login_required
def my_view(request):
    ...

in your base.html, add your check

{% if user.is_authenticated %}
  {% block page %}
  {% endblock %}
{% else %}
  <p>Please Log in</p>
{% endif %}

then with all your other pages, add {% extends 'base.html' %} at the top. You will need to give it a relative link to base.html. Then the rest of your code on that page needs to sit between tags like below.

{% block page %}
<!-- all your html code here -->
{% endblock %}

Notice that after block, you need to have the same name. for this example, it is page but you can pick your own variable name.
