Cache key does not match, what problem could it be? about django-health-check HOT 7 CLOSED

The cache backend is trying to set a key and get that key. If it's not able to do so, it will raise an exception.

        try:
            cache.set(self.cache_key, "itworks")
            if not cache.get(self.cache_key) == "itworks":
                raise ServiceUnavailable(f"Cache key {self.cache_key} does not match")

from django-health-check.

should print self.cache_key, but it just writes Cache key does not match. Could it be that it hasn't set any keys?

from django-health-check.

Yes, that is correct

from django-health-check.

ok but then the problem is not that he hasn't set any key to db, but that self.cache_key has no value

from django-health-check.

The value of the key is shown in the code above. "itworks" is the value being set to "self.cache_key".

from django-health-check.

ok but why the error is Cache key does not match? it could be Cache key djangohealthcheck_test does not match

self.cache_key could be djangohealthcheck_test.
maybe self.cache_key has no value, i didn't set HEALTHCHECK_CACHE_KEY in my django project

self.cache_key = getattr(
            settings, "HEALTHCHECK_CACHE_KEY", "djangohealthcheck_test"
        )

from django-health-check.

It's saying that the value of the cache key does not match what was supposed to have been set, it's not trying to list the key's name at all.

You don't need to set it, by default it uses the key "djangohealthcheck_test".

Based on the issues you're describing at the top of the post:

1. You don't have Django's caching framework configured at all, if that is the case then you should not include the cache health check as it's always going to fail.
2. You do have cache setup, but it's configuration is broken or the cache (Redis, memcache, etc.) is not running
