How to invalidate the model caching in ruby?


Hello All,

I used rails caching to cache the model as in model language.rb file

def self.cached_languages
return Rails.cache.fetch(‘languages’) { Language.all }

Now I want to add/delete some new language to database. So when the
table “languages” changes it should reflect in view. For that I want to
invalidate the cache.

please tell me How i do that?
