Question

我有一个很大的问题，我无法弄明白。

我试图在节目动作中生成一个页面：

# projects_controller.rb

def show
    @project = Project.find(params[:id])

    respond_to do |format|
      format.html
      format.pdf do
        render  :pdf => "#{@project.id}-#{@project.name}",
                :template => 'projects/show.pdf.erb',
                :layout => 'layouts/pdf.html.erb',
                :encoding => "utf-8",
                :show_as_html => params[:debug].present?
      end
    end
end

但是，在此视图中，我通过回形针获得了一些上传文件，当我尝试输入http://localhost:3000/projects/1.pdf时，例如它抛出一个错误：

Sprockets::FileOutsidePaths in Projects#show

Showing /Users/victorrodrigues/Sites/ror/linhadefrente/app/views/projects/show.pdf.erb where line #342 raised:

/system/upload/platforms/14/icon/small/revista.png?2011 isn't in paths:    /Users/victorrodrigues/Sites/ror/linhadefrente/app/assets/fontface, /Users/victorrodrigues/Sites/ror/linhadefrente/app/assets/images, /Users/victorrodrigues/Sites/ror/linhadefrente/app/assets/javascripts, /Users/victorrodrigues/Sites/ror/linhadefrente/app/assets/stylesheets, /Users/victorrodrigues/Sites/ror/linhadefrente/vendor/assets/stylesheets, /Users/victorrodrigues/.rvm/gems/ruby-1.8.7-p352@linhadefrente/gems/jquery-rails-1.0.14/vendor/assets/javascripts, /Users/victorrodrigues/Sites/ror/linhadefrente/app/assets/fontface, /Users/victorrodrigues/Sites/ror/linhadefrente/public/system

我尝试添加“系统”路径：

# application.rb
config.assets.paths << "#{Rails.root}/public/system"

但我不知道如何解决这个问题，有人可以提供帮助吗？感谢

Answer 1

这似乎是一个宝石不兼容问题。

尝试gem "sprockets", "2.0"

有关详细信息，请参阅LINK。

Answer 2

如果你已经有sprockets 2.0或更高版本，并且移动了包含你所指的文件的文件夹（例如我将我的模板文件夹从javascripts移动到资源），那么它可能只是一个缓存问题。我重启了电脑，工作正常。
