I am stuck on an issue with running prawn in production.
I have followed the Railscast (revised http://railscasts.com/episodes/153-pdfs-with-prawn-revised?view=asciicast) pretty much to the letter. It works great in my development environment (Mac OS X 10.9.1) but causes unicorn to falter on my server. My production server is (Redhat => Red Hat Enterprise Linux Server release 6.4 (Santiago)). I have the gem installed via Gemfile.
Gemfile:
gem 'prawn'
gem 'prawn-qrcode'
Controller: (show action)
def show
#@classroom = Classroom.find(params[:id])
@classroom = find_classroom
@page_title = @classroom.location.name
@classroom_alt = @classroom.location.name + " - " + @classroom.room_number
@building = find_building(@classroom.location_id)
@owner = Owner.find(@classroom.owner_id)
@room_schedule_contact = RoomScheduleContact.find_by rmrecnbr:(@classroom.rmrecnbr)
@building_image = @building.picture.url(:medium).to_s
@building_sign_image = @building.building_sign.url(:thumb).to_s
@search = Classroom.search(params[:search])
#@classroom_herprod = Building.find(params[:location_id]).building_short_code
respond_to do |format|
format.html # show.html.erb
format.png { render :qrcode => "http://rooms.lsa.umich.edu/classrooms/#{@classroom.facility_code_heprod}", :level => :l, :unit => 8 }
format.pdf do
pdf = ClassroomPdf.new(@classroom)
send_data pdf.render, type: "application/pdf",
disposition: "inline"
end
end
end
I have a pdfs directory with a classroom_pdf.rb file that includes the following.
class ClassroomPdf < Prawn::Document
def initialize(classroom)
super(top_margin: 70)
text "This is a pdf"
end
end
(This is stripped down from what I had, but it is the most basic version that works on my dev system and fails on production).
I am running the following
ruby 2.1.0p0 (2013-12-25 revision 44422) [x86_64-linux] gem 'rails', '4.0.2'
The error in the unicorn.stderr.log is as follows.

Any ideas?
