Cannot define multiple 'included' blocks for a Concern with sidekiq

2
votes

I am experiencing the below exception if I am running the sidekiq:

It can be seen that the date_at_relative_to_now class is required twice by some weird reason despite the fact that I am not using require nor require_relative in my application. I am relying exclusively to rails autoload feature.

Any ide or help is appreciated

The code for date_at_relative_to_now.rb:

module DateAtRelativeToNow
  puts 'loading...'
  extend ActiveSupport::Concern

  included do
    include ActionView::Helpers::DateHelper
  end

  module ClassMethods
    attr_reader :field

    def applicable_to?(object, _context)
      field = self.field
      object.respond_to? field
    end

    def applicable_to(field)
      @field = field

      define_method field do
        date = __getobj__.send self.__class__.field
        if date.present?
          "#{distance_of_time_in_words_to_now date} ago"
        else
          'Never'
        end
      end
    end
  end
end

Can you share the code of date_at_relative_to_now.rb class?. – Sanjiv

Issue occuring as activesupport does not support include inside 'included' block.

Remove include ActionView::Helpers::DateHelper line from DateAtRelativeToNow and included it in module or class wherever you need.

Implemention of activesupport 'included' function:

        def included(base = nil, &block)
          if base.nil?
            raise MultipleIncludedBlocks if instance_variable_defined?(:@_included_block)

            @_included_block = block
          else
            super
          end
        end
