Rails错误“参数数量错误（1代表0）”

Question

I am using a scope to filter my results :

@hotels = @hotels.type(params[:hotel_type]) unless params[:hotel_type].blank?

with

scope :type, lambda { |type|
  self.scoped.where('hotel_type_id IN ( ? )', type.join(', ')) unless type.blank?
}

And params[:hotel_type] = ["2","3"]

Anyone can help me? I think it's because it's an array but i don't know how to fix this.

Thank you

我认为您无法命名您的范围type ，我将其命名为by_type
