Detecting if my page is being loaded in an iFrame in a Django view

Question

How can I detect in a view function that the page is being loaded in an iFrame? I want to change the page slightly if that is the case. Is there any way to do this?

Note, Im not looking for click jacking protection. I want to make changes to my view if the page is being loaded in an iframe.

You can check the {{ request.META.HTTP_SEC_FETCH_DEST }} variable in the template. Example:

<section id="header" class="hero is-small is-info {% if request.META.HTTP_SEC_FETCH_DEST != 'document' %}is-hidden{% endif %}">
