Footnotes.setup do |f|
f.enabled = Rails.env.development?
end if defined?(Footnotes) && Footnotes.respond_to?(:setup)

I start app in development mode, and nothing happens and nothing appears(

I tried add div in layout with id="footnotes_holder"

but it empty always(

There are no errors, but nothing happens.

At least in my case that was because I am using Puma with threads. I'm not sure why, but this piece of code uses thread-local-storage members to enable footnotes:

rails-footnotes/lib/rails-footnotes.rb

Lines 11 to 13 in f46e14c

	thread_mattr_accessor :before_hooks
	thread_mattr_accessor :after_hooks
	thread_mattr_accessor :enabled, default: false

Changing thread_mattr_accessor to mattr_accessor fixed it for me.

I am far from a Ruby expert, but this monkey-patch in config/initializers/rails_footnotes.rb worked for me:

module Footnotes
  # the original implementation uses thread_mattr_accessor which doesn't work well with puma.
  # puma creates multiple threads and each of them has a different value for the same variable.
  # Footnotes.setup below only happens on the main thread and the value is NOT shared.
  # this code below is a workaround to make it work with puma.
  mattr_accessor :before_hooks, default: []
  mattr_accessor :after_hooks, default: []
  mattr_accessor :enabled, default: false
end

Footnotes.setup do |f|
  f.enabled = Rails.env.development?
end
