The procedure to put the Git timestamp in the STATIC_URL setting consists of the following two steps:

1. Add the following content to the misc.py file placed in utils/:

# utils/misc.py
import subprocess
from datetime import datetime

def get_git_changeset(absolute_path):
    repo_dir = absolute_path
    git_show = subprocess.Popen(
        "git show --pretty=format:%ct --quiet HEAD",
        stdout=subprocess.PIPE,
        stderr=subprocess.PIPE,
        shell=True,
        cwd=repo_dir,
        universal_newlines=True)
    timestamp = git_show.communicate()[0].partition(‘
’)[0]
    try:
        timestamp = datetime.utcfromtimestamp(int(timestamp))
    except ValueError:
        return ""
    changeset = timestamp.strftime(‘%Y%m%d%H%M%S’)
    return changeset

2. Import the newly created get_git_changeset() function in the settings and use it for the STATIC_URL path, as follows:

# settings.py
# ... somewhere after BASE_DIR definition ...
from utils.misc import get_git_changeset
STATIC_URL = f'/static/{get_git_changeset(BASE_DIR)}/'
