Question

我正在试图弄清楚为什么我的编辑操作不会更新记录。我已多次检查我的控制器编辑和更新操作，但找不到任何错误。我错过了什么？感谢。

goals_controller.rb

def edit
  @goal = Goal.find(params[:id])
end

def update
  @goal = Goal.find(params[:id])
  if @goal.update_attributes(params[:goal])
    flash[:notice] = "Successfully updated goal."
    redirect_to goals_url
  else
    render :action => 'edit'
  end
end

来自控制台的消息：
