Answer 1

You should use

{% ifnotequal... 
{% ifequal...

etc :)

Here is all: http://docs.djangoproject.com/en/dev/topics/templates/#topics-templates

Answer 2

Check out Django smart-if template tag http://simonwillison.net/2009/Mar/3/smartif/ http://www.djangosnippets.org/snippets/1350/

It replaces the built-in if tag and lets you do comparison operators.

Answer 3

Instead of continually posting here every time you have a minor problem, you should read Django's excellent documentation. In particular, the template docs have a very good explanation of why what you have tried is not allowed.

In this case, you could benefit from the fact that in Python 0 is the same as False. So you could have

{% if variable %}

or

{% if not variable %}

Otherwise, use {% ifequal %} and {% ifnotequal %} as MaRiz explains.
