Example: /static/img/ /static/js/ /static/css/ /templates/ urls.py settings.py I then have the following rule in my urls.py file:

阅读更多关于 Multiply by -1 in a Django template

问题 I'd like to always use a positive value of my variable in a Django template. The variable's sign is just a textual meaning: {% if qty > 0 %} Please, sell {{ qty }} products. {% elif qty < 0 %} Please, buy {{ -qty }} products. {% endif %} Of course, {{ -qty }} doesn't work.
