sidekiq and rails truncate helper

Question

I'm trying to use the Rails truncate helper inside of Sidekiq. Everything works fine outside of Sidekiq but inside sidekiq when I try to process the job it gives me:

NoMethodError: undefined method `each_byte' for nil:NilClass

This is because Sidekiq contains it's own truncate method:

http://www.rubydoc.info/gems/sidekiq/3.3.1/Sidekiq/WebHelpers:truncate

The problem is it's too simple compared to the Rails helper and I need to be able to truncate words as opposed to chars. So I tried to use the method explictly:

content = ActionView::Helpers::TextHelper.truncate(content.gsub(/\n/, ''), :length => 126, :separator => ' ', :omission => '', :escape => false)

But this still gave me the same error as before.

Additionally, I also tried including the helper in the top of the class

include ActionView::Helpers::TextHelper

But that didn't seem to make any difference. Any ideas how I can use the Rails truncate method inside Sidekiq?

Thanks,

Just open source code by your link above Source: hide | on GitHub Source: hide | on GitHub :

def truncate(text, options = {}, &block)
  if text
    length  = options.fetch(:length, 30)

    content = text.truncate(length, options) // <--
    content = options[:escape] == false ? content.html_safe : ERB::Util.html_escape(content)
    content << capture(&block) if block_given? && text.length > length
    content
  end
end

As you can see this method just using truncate method of String . Just use it instead of ActionView helper.
