cache not working

[passalini]

I google and try a lot, but I just can't see/do the AMS's cache work.
Right now I'm in development env using 0.10.0.rc3

ps: I can use Rails.cache normally

# enviroments/development.rb
  config.action_controller.perform_caching = true
  config.cache_store = :dalli_store, 'localhost:11211'

# lesson_serializer.rb
class LessonSerializer < ActiveModel::Serializer
  cache key: 'lesson-serialized'
  delegate :cache_key, to: :object

  attributes ....
end

Any help will be very welcome!!

Update

I can see the cache working on ubuntu 15.04 but not in my other machine, OS X Yosemite 10.10.5,
both using rbenv, ruby 2.1.5 and rails 4.2.1.

I will close the issue, but when I figure out why it does not work in osx, I will do an updade here!

@passalini Great, please keep us posted if you find the reason so that we can include it in an FAQ.

@beauby today the code just work, memory's garbage perhaps? I don't konw yet, but if I figure out I will come back.

I have a similar issue, I was on 0.10.0.rc3 (specifically https://github.com/rails-api/active_model_serializers/tree/efe5128a2e6b8578d81bc7a807ace427c0b4d847) and updated to today's master (specifically https://github.com/rails-api/active_model_serializers/tree/df594c630db5b11c1c0b7c9f053fa4275a2ee035) and suddenly caching via cache key: some_key inside the serializer just stopped working, or at least no cache reads/writes are logged to the console. Caching via Rails.cache.fetch in the controller still works though.

I tried to find the last commit where caching still worked and 21fe3ab is the last one. Starting from 170db3b the caching stopped working.

I'm using OS X El Capitan, ruby '2.3.0' and rails 4.2.1.

config.action_controller.perform_caching = true is enabled

@sevab There's an open issue for this at #923 (comment) if you'd like to repost there.

Also, I'm having a heckavu time demonstrating caching as improving performance, and when that went away. See #1393 and I think #1352 might help. So, I'd appreciate any code you could share demonstrating the change in behavior and performance. Maybe join the slack? https://github.com/rails-api/active_model_serializers#getting-help
