Question

我的控制器出了问题。我的参数评分未保存在我的列rating_score中。

我的控制器：

  def rate
    @konkurrancer = Konkurrancer.find(params[:id])
    @container = "Konkurrancer"+@konkurrancer.id.to_s

    @konkurrancer.rating_score += params[:rating].to_i
    @konkurrancer.ratings += 1
    @konkurrancer.save

    respond_to do |format|
      format.js
    end
  end

控制台日志：

评级作为参数传递，格式如下：

params[:vind][:rating]

将控制器中的相关行从params[:rating]更改为params[:vind][:rating]，它应该可以正常工作。

Rails帮助控制器不保存参数
