casting ints to str in Jinja2

Question

I want to cast an int that\'s passed to the template through the url, but it says that the str function isn\'t defined.

How do I get around this?

Jinja2 also defines the ~ operator, which automatically converts arguments to string first, as an alternative to the + operator.

Example:

{% set p = year ~ '/' ~ month ~ '/' ~ day ~ '/' ~ post.slug %}

See Other operators or, if you really want to use str, modify the Environment.globals dictionary.
