使用redis-rails，如何删除除会话缓存以外的所有内容？

Question

Rails 5.1 app, redis-rails gem 5.0.2 Rails 5.1应用程式，redis-rails gem 5.0.2

Gemfile 的Gemfile

gem "rails", "~> 5.1"
gem "redis-rails"

in production.rb 在production.rb中

config.cache_store = :redis_store, ENV.fetch("REDISCLOUD_URL")

in session_store.rb 在session_store.rb中

Rails.application.config.session_store :redis_store, servers: [ENV.fetch("REDISCLOUD_URL")]

I would like to be able to clear cache time to time and I can run 我希望能够不时清除缓存并可以运行

Rails.cache.clear

for that. 为了那个原因。 However, it clears everything and I don't want to remove sessions. 但是，它清除了所有内容，并且我不想删除会话。

I tried namespaces but can't find much of documentation anywhere ( https://github.com/redis-store/redis-rails ) 我尝试了名称空间，但在任何地方都找不到太多文档（ https://github.com/redis-store/redis-rails ）

What commands, configs, approach I can take to solve this? 我可以采取哪些命令，配置和方法来解决此问题？ Thank you. 谢谢。

Maybe you can get all cache keys 也许您可以获得所有缓存键

Rails.cache.instance_variable_get(:@data).keys

and use it in combination with delete_entry excluding the session keys. 并将其与不包含会话密钥的delete_entry结合使用。
