Re: Can we use python related api's on the Django templates ?

While you cannot use Python operators and functions directly in the templates, you can write your own "wrappers" around those you need: https://docs.djangoproject.com/en/3.0/howto/custom-template-tags/ On Wednesday, 27 May 2020 15:57:34 UTC+2, Daniel Roseman wrote: > > On Wednesday, 27 May 2020
