Disable features without required Redis modules Some features, like querying and embedded models, require either the RediSearch or RedisJSON modules running in Redis. Without these modules, using these features would result in inscrutable errors. We now disable some tests if the Redis module required for the test is not found in the Redis instance the tests are using, and raise errors or log messages if the same is true during execution of HashModel and JsonModel. 2021-11-03 12:37:09 -07:00			`from functools import lru_cache`
