undefined method `cache_getter' for Typhoeus::Hydra

Question

I don't know why I get this error. Both methods are corrects.

hydra = Typhoeus::Hydra.new

             hydra.cache_getter do |request|
                Rails.cache.read(request.cache_key) rescue nil
             end
             hydra.cache_setter do |request|
               Rails.cache.write(request.cache_key,request.response, expires_in: request.cache_timeout)
             end

Answer 1

You are getting that error because those methods do not exist on an instance of Typhoeus::Hydra. You can find the full list of available methods at http://rubydoc.info/gems/typhoeus/0.5.0/frames

Update

Those methods were removed between versions 0.4.2 and 0.5.0 via this commit
