How to convert string to uppercase / lowercase in Jinja2?

January 14, 2023 by Tarik

Filters are used with the |filter syntax:

{% elif  student.department|upper != "MATHS DEPARTMENT" %}
    Maths department
{% endif %}

or you can use the str.upper() method:

{% elif  student.department.upper() != "MATHS DEPARTMENT" %}
    Maths department
{% endif %}

Jinja syntax is Python-like, not actual Python.
