What is the use of parent_template filter in Django templates

[Prateek]

I am reading Django Unleashed in which the author uses the following code to extends the template

{% extends parent_template|default:"organizer/base_organizer.html" %}

What does parent_template do ?

I am unable to find this tag in the Django Documentation

Is there any variable called parent_template in the context ?

Hi Prateek,
Thanks for buying my book!

The first time we use parent_template---a variable, not a template tag---is on page 108 of the book. The paragraph before Example 4.53 provides a full explanation of why I opt to use a variable with a default, rather than a magic (read: hardcoded) string.

Hope that's helpful!

Andrew
