Using helpers inside builder

[dimoreira]

How can one use a Rails helper inside the builder class?
I already tried to include the helper but this didn't work for me.

My example:

class UserCreditsCSVBuilder < Julia::Builder
    include ActionView::Helpers::NumberHelper

    column "Value" do |c|
        number_to_currency c.amount
    end
end

While I would have expected include to be the right inheritance method, I tried extend and it worked:

class DevelopmentCsv < Julia::Builder
  extend ActionView::Helpers::DateHelper

  column "Value" do |c|
    time_ago_in_words c.created_at
  end
end

DevelopmentCsv.build([Development.first])
#=> "Value\nabout 20 hours\n"

I assume this has something to do with the DSL-style syntax, since other objects in my app (like presenters) which use standard method definition, include the functionality correctly using include.

class EditPresenter < Burgundy::Item
  include ActionView::Helpers::DateHelper
  def time_ago
    "#{time_ago_in_words(created_at)} ago"
  end
end

@dimoreira extend will do the job for now (thanks @beechnut), but you're right, it should be include, I'll keep this issue open in order to fix it.

@beechnut @stevenbarragan Great guys. I will try extend for now. And keep an eye on this thread to see updates on code semantics.

Thanks
