[Python] How to check if a Django template block is overridden in the child template?

I am working on a Django project where I have a base layout template (main.html) and a child template (dashboard.html).

I want to modify the tag so that if the child template provides a title, it should be formatted as: Page Title | Application

Otherwise, if the block is empty or not overridden, it should just be: Application (without the extra | Application).

Here’s my main.html:

{% load static %}
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>
{% block title %}{% endblock %}{% if block.super %} | Application{% endif %}
</title>
<link rel="stylesheet" href="{% static 'assets/css/style.css' %}">
</head>
<body>
{% block content %}{% endblock %}
</body>
</html>


And here’s my dashboard.html:

{% extends 'core/layouts/main.html' %}

{% block title %}Dashboard{% endblock %}

{% block content %}
<h2>Welcome, {{ user.name }}</h2>
<a href="{% url 'logout' %}">Logout</a>
{% endblock %}


Issue: When the child template doesn't override the title block, the output is:

| Application


Instead of just:

Application


How can I check whether a block is overridden in the child template and adjust the title accordingly?

Would appreciate any suggestions. Thanks!
