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 variables %} {% endblock %} {% if bool_var %} {{ option_a }} {% else %} {{ option_b }} {% endif %} child.html:
{% extends "parent.html" %} {% block variables %} {% set bool_var = True %} {% set option_a = 'Text specific to this child template' %} {% set option_b = 'More text specific to this child template' %} {% endblock %} But the variables end up undefined in the parent.

Some of the features of Jinja are: sandboxed execution. automatic HTML escaping to prevent cross-site scripting (XSS) attacks. template inheritance.
Jinja2 being a templating language has no need for wide choice of loop types so we only get for loop. For loops start with {% for my_item in my_collection %} and end with {% endfor %} . This is very similar to how you'd loop over an iterable in Python.
The default Jinja delimiters are configured as follows: {% ... %} for Statements. {{ ... }} for Expressions to print to the template output. {# ... #} for Comments not included in the template output.
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' %} If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
