pdf无法呈现pdf 500错误
我无法让wicked_pdf在Mac OSX 10.8.2，Ruby 1.9.2，Rails 3.2.11的本地工作
如果任何人有任何智慧分享这个问题，请做。
在我的Gemfile中我有：
gem "wicked_pdf"
group :development do
gem "wkhtmltopdf"
gem "wkhtmltopdf-binary"
...
end
group :production do
gem "wkhtmltopdf-heroku"
end
我的控制器中有以下内容：
def show
...
respond_to do |format|
format.html
format.pdf do
render :pdf => 'filename',
:handlers => [:haml]
end
end
end
在我看来，我有这个链接：
= link_to 'Create PDF document', consultant_path(@consultant, :format => :pdf)
点击时得到相同的URL并在其末尾添加.pdf。
这是从日志中获得输出的内容。

看起来邪恶在工作，但渲染失败了？
