Django {% if custom_template_tag > 0 %} does not work -

i've got these template tags

@register.assignment_tag def test1():     return 2  @register.simple_tag def test2():     return 2 

in template i've got this

{% test1 test1_var %}     {% if test1_var > 0 %}test1{% endif %}  {% if test2 > 0 %}test2{% endif %} 

results in test1

what want template tag appears if greater 0, cannot believe assignment_tag right solution that. why test2 not work?

the test2 inside if statement not call template tag; can refer (non-existent) context variable. that's why assignment tag works, because set such variable.

if don't assignment tag, might consider doing whole comparison inside tag, outputs test1/test2 value directly.
