if and extends in template

[0ptr]

{% if mobile %}
{% extends 'base_mobile.html' %}
{% else %}
{% extends 'base_normal.html' %}
{% endif %}

Throws following exception:

Exception Type:	TemplateSyntaxError
Exception Value:	
Invalid block tag: 'else'
Exception Location:	/home/dsduser/django-synble/django/template/__init__.py in invalid_block_tag, line 333

I think this should be supported. Second option is to write include correctly so that include does not broke inheritance. E.g.:

basbase.html: has block

base.html: include "basebase.html"

logic.html: extends "base.html", inheritance of basbase.html block does not work here anymore.

Ok actually better way is to return the template name from context processor and extend it directly

{% extends ua_based_template %}
