153.PDFs with Prawn
错误：
Your document includes text that's not compatible with the Windows-1252 character set. If you need full UTF-8 support, use TTF fonts instead of PDF's built-in fonts .
寻找字体解决：在mac的font book中找到宋体，拷贝。代码显示如下：
#clients_controller.rb
def download_pdf
client = Client.find(params[:id])
send_data generate_pdf(client), filename: "#{client.name}.pdf", type: "application/pdf"
end
private
def generate_pdf(client)
Prawn::Document.new do
#建立字体
font_families["msyh"] = {
:normal => { :file => "/Users/jayzen/Desktop/Fangsong.ttf" }
}
#使用已经创建好的字体进行显示
font("msyh") do
text client.name, align: :center
text "Address: #{client.address}"
text "Email: #{client.email}"
end
end.render
end
402.Better Errors & RailsPanel
本章节是介绍在开发模式下面的几个gem,用于调试错误和观察运行时状况，其中内容在gorails里面也有提到，这个章节主要是增加一个gem,和一个chrome插件，完整的gem列表如下：
group :development do
gem 'better_errors'
gem 'binding_of_caller'
gem 'meta_request'
end
另外chrome的插件名称为RailsPanel。
