ifnotequal
Show a block when two values are not equal.
The {% ifnotequal %}
tag tests if its two arguments are unequal. If so then the contents of the {% ifnotequal %}
block are output, otherwise the contents of the optional {% else %}
block are output.
For example:
{% ifnotequal value 5 %}
Value is {{ value }} which is not 5.
{% else %}
Value is 5.
{% endifnotequal %}
It is only possible to compare arguments that are variables (with optional filters) or constants. Examples of constants are numbers, strings or lists.
