Django templates syntax error when using {% extends %} within if-block

Question

Is there any problem with the syntax in the following code, there is a error as Invalid block tag: 'else'

{% ifequal chat_profile 1 %}
    {% extends "chatprofile/chat_profile1.html" %}
{% else %}
    {% extends "chatprofile/chat_profile.html" %}
{% endifequal %}

Answer 1

The documentation states:

If you use {% extends %} in a template, it must be the first template tag in that template. Template inheritance won't work, otherwise.

So consider using a design where you can use {% include %} instead.
