为此，我看到的最优雅的解决方案是做两件事:基于请求中的用户代理识别移动用户并使用自定义的Rails哑剧进行响应，从而允许移动用户使用自定义HTML模板.

The most elegant solution for this I've seen is to do two things: recognize mobile users based on user-agent in the request and use a custom Rails mime type to respond with, allowing custom HTML templates for mobile users.

在config/initializers/mime_types.rb中定义只是HTML的自定义移动" Rails MIME类型:

Define a custom 'mobile' Rails MIME type in config/initializers/mime_types.rb that's just HTML:

Mime::Type.register_alias "text/html", :mobile

添加帮助者/过滤器以响应移动用户:

Add a helper/filter to respond to mobile users:

def mobile_user_agent?
  @mobile_user_agent ||= ( request.env["HTTP_USER_AGENT"] && request.env["HTTP_USER_AGENT"][/(Mobile\/.+Safari)/] )
end

然后..

before_filter :handle_mobile

def handle_mobile
  request.format = :mobile if mobile_user_agent?
end

制作自定义移动模板:

app/views/users/show.html.erb => app/views/users/show.mobile.erb

在控制器中调度移动设备或常规设备:

Dispatch mobile or regular in controllers:

respond_to do |format|
  format.html { }   # Regular stuff
  format.mobile { } # other stuff
end
