ruby-on-rails-4 - 无法在Rails4中将.xls注册为自定义MIME类型

Question

我已经更新了 config/initializers/mime_types.rb 并重新启动了服务器。

Mime::Type.register "application/vnd.sealed-xls", :xls

我的 Controller 如下所示:

respond_to do |format|
  format.xls {  send_file(file_name, filename:  "dagsrapport.xls")  }
  format.html
end

这是我在 /sheet.xls上执行GET时遇到的错误

To respond to a custom format, register it as a MIME type first: 
http://guides.rubyonrails.org/action_controller_overview.html#restful-downloads. If you meant to 
respond to a variant like :tablet or :phone, not a custom format, be sure to nest your variant 
response within a format response: format.html { |html| html.tablet { ... } }

关于我所缺少的任何提示吗？根据文档，我看不到我在做什么错: http://guides.rubyonrails.org/action_controller_overview.html#restful-downloads

我所做的所有将xls注册为Mime类型的操作-刚添加到 config/initializers/mime_types.rb Mime::Type.register "application/xls", :xls并重新启动服务器。希望能对您有所帮助。
