Ruby on Rails全球Cach

Question

I need some global variable on my server that will always be there Is there a built in way to use some global cache on a rails server?

I'm looking for a query cache that will last for an hour.

Is it recommended?

Answer 1

I always put variables I want to access everywhere into the environments/{production,development,..}.rb files, depending of the environment. If you want some fast datastore, which needs to store some more complex data, I would suggest redis . If redis is to heavy for your use case you can also use the Rails Caching .

Answer 2

you can always add an app specific yaml file that you load from a file in initializers

in initializers:

raw_config = File.read("#{Rails.root}/config/app_config.yml")

APP_CONFIG = YAML.load(raw_config)[Rails.env].symbolize_keys

then you can access APP_CONFIG from anywhere in your app APP_CONFIG[:some_var]
