Rails javascript_include_tag tags in liquid

Question

I'm trying to get javascript_include_tag("jquery") to work in a Liquid tag inside rails. My problem is that javascript_include_tag("jquery") returns <script src="/javascript/jquery.js"></script>. And not: <script src="/assets/jquery_ujs.js"></script>. Also in production the tag does not add the file fingerprint.

  class JqueryTag < ::Liquid::Tag
    # Include the stylesheet tag link helper
    include ActionView::Helpers::AssetTagHelper


    def render(context)
      return javascript_include_tag("jquery")
    end

  end

  Liquid::Template.register_tag('jquery_tag', JqueryTag)

Finaly found an answer.

Including include ActionView::Helpers::AssetTagHelper was not enough.

Instead i needed to do this.

  class JqueryTag < ::Liquid::Tag

    def render(context)
      helpers.javascript_include_tag("jquery")
    end

    def helpers
      @helpers ||= ActionController::Base.helpers
    end

  end

  Liquid::Template.register_tag('jquery_tag', JqueryTag)
