PDFKit Overview & Advanced Usage @MetaSkills.net Last week I had the pleasure of rewriting 4 years of legacy PDF::Writer code to PDFKit. Why? Well drawing pdfs in ruby using libraries like PDF::Writer is like composing a webpage with an Etch A Sketch. In short, its a damn chore that involves a bunch of code that mixes both data and presentation. Wkhtmltopdf is an open source project that uses the WebKit rendering engine to convert HTML to native PDF code. Installation Installing the PDFKit gem is a no brainer. $ which wkhtmltopdf /usr/local/bin/wkhtmltopdf The Basic Requirements I knew that HTML to PDF generation has its drawbacks, specifically with common headers/footers and page breaks.

Fixes para Ruby 1.9, Rails 2.3.x e Unicode Ainda existem alguns problemas entre o Rails 2.3, o Ruby 1.9 e seu suporte a UTF-8 e a forma como ambos o ERB (Embedded Ruby, a engine padrão para templates que usamos no ActionView) e o adapter de MySQL tratam encoding. Notei isso quando testei meu próprio blog rodando sobre Ruby 1.9 e ele dá o seguinte erro quando tento carregar a aplicação em algum navegador: O erro aponta justamente para uma linha onde eu puxo dados de um activerecord. Há duas chances para isso: ou o ERB está tratando o encoding errado ou o ActiveRecord está recebendo o dado com encoding errado. No meu caso acho que é o segundo caso.

CoffeeScript Basics – A Teach Me To Code Tutorial CoffeeScript is now going to be a default installation with Ruby on Rails.
