Question

{{ is_true }}

{% if is_true == "True" %}
    <h2>Say True</h2>
{% else %}
    <h2> False </h2>
{% endif %}

But instead it went to else clause even though {{ is_true }} returns True

Any idea?

def some_func():
   if ....:
     return True
   else:
     return False

Answer 1

You don’t need to use "True" in your template:

{% if is_true == True %}

Or just:

{% if is_true %}

If you use "True" in your template then you are comparing the boolean True with the string "True" (which are not the same) and end up in the else clause of your template.
In other words you would be doing:

{% if True == "True" %}
    <h2>Say True</h2>
{% else %}                     # You will end up here
    <h2> False </h2>
{% endif %}
