移动格式的Javascript方法不起作用(既不是JS也不是HTML)

我有一个类似reddit的应用,允许用户投票选择Activerecord Reputation System gem的链接。

我正在尝试创建基于Railscast#199的移动版本,如果通过移动设备访问该网站,则会使用mobile.erb格式。

投票方法在非移动格式下工作正常(默认为javascript,但也适用于html),但在移动设备中返回错误,如下所示。请注意,它正在尝试Get而不是Post

Started GET "/links/98/vote?type=like" for 127.0.0.1 at 2012-12-25 19:16:45 -0500
ActionController::RoutingError (No route matches [GET] "/links/98/vote"):

可能导致这种情况的原因是什么? before_filter阻止了javascript吗?我怎样才能解决这个问题?非常感谢您的投入!

application_controller.rb

before_filter :prepare_for_mobile

def prepare_for_mobile
  session[:mobile_param] = params[:mobile] if params[:mobile]
  request.format = :mobile if mobile_device?
end

def mobile_device?
  if session[:mobile_param]
    session[:mobile_param] == "1"
  else
    request.user_agent =~ /Mobile/
  end
end
helper_method :mobile_device?

的routes.rb

resources :links do
  member { post :vote }
end

links_controller.rb

def vote
  value = params[:type] == "like" ? 1 : 0
  @link = Link.find(params[:id])
  @link.add_or_update_evaluation(:link_votes, value, current_user)
  respond_to do |format|
    format.html { redirect_to :back }
    format.mobile { redirect_to :back }
    format.js
  end
end

_link.mobile.erb

<div id="link_<%= @link.id %>">
  <%= link_to "like", vote_link_path(@link, type: "like"), method: "post", remote: true %>
</div>

<div id="link_points_<%= @link.id %>">
  <%= @link.reputation_for(:link_votes).to_i %>
</div>

vote.js.erb

$('#link_<%= @link.id %>').html("<%= j link_to "up", vote_link_path(@link, type: "like"), method: "post", remote: true %>");


$('#link_points_<%= @link.id %>').html("<%= @link.reputation_for(:link_votes).to_i %>;

这就是我的所作所为:

<强>配置/初始化/ mime_types.rb

Mime::Type.register_alias "text/html", :mobile
Mime::Type.register_alias "text/javascript", :mobilejs /* newly added mobilejs */

<强> application_controller.rb

before_filter :prepare_for_mobile

def prepare_for_mobile
  session[:mobile_param] = params[:mobile] if params[:mobile]
  if mobile_device?
    if request.format == :js
      request.format = :mobilejs /* newly added mobilejs format */
    else
      request.format = :mobile
    end
  end
end
