How to trim string in django template?

Question

Django

{{ str|replace:'|/\..+/g|' }} I'm trying to cut a string after a dot
on regexr.com, the expression /\..+/g selects the text after the dot, however, as I understand it, something like (/\..+/g, '') is needed - tell me how it is in template correctly to write down?

Answer 1

Create your own template tag that will do whatever you want with the string
