Pass variables from child template to parent in Jinja2

Question

I want to have one parent template and many children templates with their own variables that they pass to the parent, like so:

parent.html:

{% block          


        

Answer 1

Ah. Apparently they won't be defined when they are passed through blocks. The solution is to just remove the block tags and set it up like so:

parent.html:

{% if bool_var %}
    {{ option_a }}
{% else %}
    {{ option_b }}
{% endif %}

child.html:

{% extends "parent.html" %}

{% set bool_var = True %}
{% set option_a = 'Text specific to this child template' %}
{% set option_b = 'More text specific to this child template' %}
