# Jinja-IncludeWith
|
|
|
|
A Jinja2 preprocessor extension that let you update the `include`
|
|
context like this:
|
|
|
|
{% include "something.html" with foo=bar %}
|
|
{% include "something.html" with a=3, b=2+2, c='yes' %}
|
|
|
|
You **must** also include 'jinja2.ext.with_' in the extensions list.
