I\'m working on some universal solution for problem with static files and updates in it.

Answer 1

Simple templatetag vstatic that creates versioned static files urls that extends Django's behaviour:

from django.conf import settings
from django.contrib.staticfiles.templatetags.staticfiles import static

@register.simple_tag
def vstatic(path):
    url = static(path)
    static_version = getattr(settings, 'STATIC_VERSION', '')
    if static_version:
         url += '?v=' + static_version
    return url

If you want to automatically set STATIC_VERSION to the current git commit hash, you can use the following snippet (Python3 code adjust if necessary):

import subprocess


def get_current_commit_hash():
    try:
        return subprocess.check_output(['git', 'rev-parse', '--short', 'HEAD']).strip().decode('utf-8')
    except:
        return ''

At settings.py call get_current_commit_hash(), so this will be calculated only once:

STATIC_VERSION = get_current_commit_hash()
