替代常规宝石红宝石方法的动作缓存？

Question

Lets take an example.

def get_data(param1,param2,param3)
  #do something
  #make some api calls
end

This method not belongs to controller. I am using this method in my ruby class in my gem.How to cache the result of method based on parameter coming.Something similar to action caching in rails comes with expiration ability.

Answer 1

You can use this low level caching:

def competing_price
    Rails.cache.fetch("#{param1}-#{param2}-#{param3}", expires_in: 12.hours) do
      # do something.. 
    end
end

It has nothing related that you have to do it in controller or model only. you can use it anywhere else like your method.
