if else and if else not working in ansible template

Question

I am checking for pushing data based upon variables set true or false. My varaibles file which is json file has { "isfs" : True }

and my template (t2.j2)has below condition

{% if  '{ isfs | d() | bool }' -%} 
  <perform operation >
{% else -%}
  <perform 2 operation

Every time it executes <perform opertaion >even if change value of json file "isfs": False.

Please pour some suggestion.

I tried d(true) and also I tried with elif condition nothing helping me

Answer 1

just test the variable. This shoud do what you want. Any True or true value is supposed to return true.

{% if isfs %}

cast if needed:

{% if isfs | bool %}

edit: I think i misunderstood that you are evaluating against a json file that contains '{ "isfs" : True }'. You'll need to parse the json file to get the value. Considering the json file content is in the json_file variable:

{% if json_file.isfs %}
