Add rails 7 version specific fix for AttachmentSizeValidator

[yorzi]

I compared the COMPARE_CHECKS (Rails 7) and CHECKS (Rails 6) - This can be replaced directly.

Style/Next: Use next to skip iteration.

Layout/TrailingWhitespace: Trailing whitespace detected.

Metrics/LineLength: Line is too long. [91/80]

@ssinghi I was just about to look into this and have seen that there is already a fix in place. Would it be possible to create a 7.0.2 tag that contains this fix at all please?

I'm using master and still getting an error using 7.0.3.1:

       uninitialized constant Paperclip::Validators::AttachmentSizeValidator::CHECKS
     
                   unless value.send(CHECKS[option], option_value)
                                     ^^^^^^

I see the problem. Some extensions require paperclip in the Gemfile. Is there a way to satisfy that dependency with kt-paperclip?

Is this pushed onto the master branch yet? I'm having the same issue and I'm running 6.4.2.

I put this in an initializer.

module Paperclip
  module Validators
    class AttachmentSizeValidator
      CHECKS = COMPARE_CHECKS
    end

    class AttachmentPresenceValidator < ActiveModel::EachValidator
      def validate_each(record, attribute, value)
        if record.send("#{attribute}_file_name").blank?
          record.errors.add(attribute, :blank, **options)
        end
      end

      def self.helper_method_name
        :validates_attachment_presence
      end
    end
  end
end

      def self.helper_method_name
        :validates_attachment_presence
      end
    end
  end
end

You are the real MVP! Thank you. This fixed my issue with it.
