python - How to convert string to uppercase / lowercase in Jinja2? -

i trying convert upper case string in jinja template working on.

in template documentation, read:

upper(s)     convert value uppercase. 

so wrote code:

{% if student.departament == "academy" %}     academy {% elif  upper(student.department) != "maths department" %}     maths department {% endif %} 

but getting error:

undefinederror: 'upper' undefined 

so, how convert string uppercase in jinja2?

filters used |filter syntax:

{% elif  student.department|upper != "maths department" %}     maths department {% endif %} 

or can use str.upper() method:

{% elif  student.department.upper() != "maths department" %}     maths department {% endif %} 

jinja syntax python-like, not actual python. :-)
