How to convert string to uppercase / lowercase in Jinja2?

Question

I am trying to convert to upper case a string in a Jinja template I am working on.

In the template documentation, I read:

upper(s)
    Convert a valu         


        

Answer 1

And you can use: Filter like this

{% filter upper %}
    UPPERCASE
{% endfilter %}

Answer 2

for the capitalize

{{ 'helLo WOrlD'|capitalize }}

output

Hello world

for the uppercase

{{ 'helLo WOrlD'|upper }}

output

HELLO WORLD

Answer 3

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. :-)
