Prawn Ruby Document generate pdf

Question

 def generate_report
    tablica = []
    tablica << 1
    Prawn::Document.generate("test.pdf") { tablica.each { |a| text a } }
  end

Why this code doesn't work in Prawn??? Which code is correct??

OK I SOLVED IT IT SHOULD BE: require "rubygems" require "prawn" tablica =[] words ="Hello world" words2 ="AAA" tablica < — Michał Makaruk, Nov 30 '11 at 14:22
Not sure how that's "solving it" any differently than what the two answers already said. — Dave Newton, Nov 30 '11 at 18:21

Try this:

require 'prawn'

def generate_report
  tablica = []
  tablica << 10
  Prawn::Document.generate("test.pdf") { tablica.each { |a| text a.to_s } }
end

generate_report

You should pass parameter as 'string' in text method.

Because you're passing a number, not a string.

def generate_report
  tablica = []
  tablica << 1
  Prawn::Document.generate("test.pdf") { tablica.each { |a| text "#{a}" } }
end
