ruby-on-rails - Rails 3 返回 HTTP 406 Not Acceptable ？

Question

我有以下 Controller 代码:

  def create
    @admin = Admin.new(params[:admin])
    respond_to do |format|
      if @admin.save
        redirect_to(@admin, :notice => 'Admin was successfully created.')
      else
        render :action => "new"
      end
    end
  end

  def update
    @admin = Admin.find(params[:id])
    respond_to do |format|
      if @admin.update_attributes(params[:admin])
        redirect_to(admin_admins_path, :notice => 'Admin was successfully updated.')
      else
        render :action => "edit"
      end
    end
  end

以及以下路线:

           admin_admins GET    /admin/admins(.:format)            {:action=>"index", :controller=>"admin/admins"}
           admin_admins POST   /admin/admins(.:format)            {:action=>"create", :controller=>"admin/admins"}
        new_admin_admin GET    /admin/admins/new(.:format)        {:action=>"new", :controller=>"admin/admins"}
       edit_admin_admin GET    /admin/admins/:id/edit(.:format)   {:action=>"edit", :controller=>"admin/admins"}
            admin_admin GET    /admin/admins/:id(.:format)        {:action=>"show", :controller=>"admin/admins"}
            admin_admin PUT    /admin/admins/:id(.:format)        {:action=>"update", :controller=>"admin/admins"}
            admin_admin DELETE /admin/admins/:id(.:format)        {:action=>"destroy", :controller=>"admin/admins"}

现在，除了稍微古怪的命名之外 - 重定向总是会导致 406 Not Acceptable 。可能出了什么问题？

Answer 1

删除 respond_to do |format| block 。因为您没有指定您要响应的格式，例如format.html { #您的代码在这里} 。检查 respond_to 的文档如何正确使用。
