Fog deprecation warnings when starting Rails server

Question

I migrated my Rails app to Rails 6.0.1 and every time I startup the server I get these Fog deprecation warnings. How can I get rid of them? Funny enough I have a cloned version of this app, which doesn't give these warnings...

Did you update the gem 'fog-core'?? – Propylaeum

No, the fog gem is fixed at a certain version – Origin

What fog and/or fog-core versions are you on? – Carrollcarronade

Did you find an answer to this? I'm seeing the same warning and is quite annoying every time I invoke "rails" commands. – Asserted

My versions are fog (2.2.0) and fog-core (~> 2.1) – Asserted

Nope, no solution yet, but very annoying. – Origin

Which version of fog have you fixed it to? – Bharat

@ClemensKofler latest release fog 2.2.0 github.com/fog/fog/releases/tag/v2.2.0 – Destructor

Answer 1

Workaround solution: Stick these 2 lines above Bundler.require in your config/application.rb

...

require 'fog/core'
Fog::Logger[:deprecation] = nil

# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(*Rails.groups)

...

Destructor

Answer 2

From my understanding, you're using the whole fog library. Is there a specific reason why you're the full library, say, fog-aws? IMO there's very little benefit to using the full fog library unless you have some kind of higher level app/library that interacts with all the providers that fog offers. So I'd suggest to just require the library/libraries you need and leave the rest. This could potentially get rid of the deprecation warnings.

No specific reason, that's the way it has been setup many years ago in the application. Until Rails 6 this was no problem and didn't give these warnings. – Origin
