Django Template Ternary Operator

Django Template Ternary Operator

Django templates do not have a built-in ternary operator like some programming languages do (e.g., condition ? true_value : false_value in JavaScript or Python). However, you can achieve similar functionality using the if template tag in Django templates.

Here's how you can implement a ternary operator-like behavior in a Django template:

{% if condition %}
    {{ true_value }}
{% else %}
    {{ false_value }}
{% endif %}

In this template code:

  • condition is the expression you want to evaluate.
  • true_value is the value to display if the condition is true.
  • false_value is the value to display if the condition is false.

Here's a practical example:

<p>
    {% if user.is_authenticated %}
        Welcome, {{ user.username }}!
    {% else %}
        Please log in.
    {% endif %}
</p>

In this example, if the user is authenticated, it displays a welcome message with the username; otherwise, it prompts the user to log in.

This approach allows you to achieve conditional rendering in Django templates without a specific ternary operator.
