I am getting the following exception when trying to call cache.touch()
method.

{{{
File "PROJECT_PATH/.venv/lib/python3.8/site-
packages/django/core/cache/backends/base.py", line 135, in touch
raise NotImplementedError('subclasses of BaseCache must provide a
touch() method')
NotImplementedError: subclasses of BaseCache must provide a touch() method
}}}

{{{
# settings.py

CACHES = {
"default": {
"BACKEND": "django.core.cache.backends.locmem.LocMemCache",
"LOCATION": "unique-snowflake",
}
}

#tasks.py
from django.core.cache import cache

def test():
...
cache.touch("session_cache_ffff0000", 1500)
...

Comment:

`touch()` works for me with `LocMemCache`. I cannot reproduce this issue.
