Caching never expires

[PascalVanVlaenderen]

Hi all,

We've been happy customers of CacheCrispies and have been using do_caching true on some models.

However now we've noticed that these models are never expired, our Redis cache keeps on growing.

I read the code and the docs just specify use X as caching method.

What's the advice on ensuring the CacheCrispies models are expired without setting a default expiration on the full Rails cache?

Currently using

CacheCrispies.configure do |config|
  config.etags = false
  config.cache_store = ActiveSupport::Cache::RedisCacheStore.new(url: ENV.fetch("REDIS_URL"), expires_in: 1.hour)
end

Sorry, for the late response on this. I just can't seem to find the time to keep on top of my open source projects like I'd like to.

This is a good point though. For me, I've typically just used a cache eviction strategy that made sense, but I can see that having a more explicit TTL would be advantageous for some situations.

The customized cache_store is certainly an option, but I'm thinking it would be good to have a simpler default at the config level, and then an ability to override it at the individual serializer level.

Does does that seem reasonable for your use case @PascalVanVlaenderen?

Hi Adam,

Thank you for your response. Having the option to override per serializer is the best of both worlds. I really like that
