Convert integer to string Jinja
I found the answer.
Cast integer to string:
myOldIntValue|string
Cast string to integer:
myOldStrValue|int
Formatting someInt
as a string can be achieved through:
'{0:d}'.format(someInt)
This syntax come from ansible, that also uses Python and Jinja. behind the scene.
The OP needed to cast as string outside the {% set ... %}
.
But if that not your case you can do:
{% set curYear = 2013 | string() %}
Note that you need the parenthesis on that jinja filter.
If you're concatenating 2 variables, you can also use the ~
custom operator.
