我收到此错误并使用Rails 5.

NoMethodError(未定义方法permit' for #<Array:0x007f51cf4dc948> app/controllers/traumas_controller.rb:99:intrauma_params'app/controllers/traumas_controller.rb:25:in`create_multiple'

控制器参数如下.

在2016-10-04 20:09:36开始POST"/ traumas/create_multiple"for 127.0.0.1 +0530由TraumasController处理#create_multiple作为JS
参数:{"utf8"=>"✓","fields"=> [ {"contusions"=>"1","burns"=>"","at_scene"=>"在场景","emergency_detail_id"=>"96","trauma_region"=>"后仰"}, "提交"=> "提交"}

我试图在控制器中创建如下记录:

  def create_multiple
    trauma_params
    params[:fields].each do |values|
       u = Trauma.create(values)
    end
  end

def trauma_params
        params.require(:fields).permit(:fields => [])
end

请帮我解决这个问题.

提前致谢.

我正在尝试使用http://alessiofanelli.com/blog/building-a-rails-5-and-ember-js-app创建一个Rails 5 api应用程序.

我明白了

找不到api_controller.rb

执行scaffold命令时出错,如下所示.

$ rails g scaffold team name:string city:string championships:integer

我能够显示集群标记的内容，但无法显示单个标记的内容。

请找到以下代码，其中 else 语句将处理单个标记。

map.eachLayer(function(marker) {  
   if (marker.getChildCount) { // to get cluster marker details
     console.log('cluster length ' + marker.getAllChildMarkers().length);
   } else {
     // how to display the contents of a single marker ??

     alert(marker.options.title); // doesn't work
   }

谢谢。
