Ruby on rails 公共活动删除

我在我的rails应用程序上为guidelines模型进行了公共_活动。但是删除一条指导原则会有问题。更新和创建指导原则很好

错误是

ActiveRecord::RecordNotSaved (You cannot call create unless the parent is saved):
  app/controllers/guidelines_controller.rb:228:in `destroy'

指南\u controller.rb

def destroy
    @guideline = Guideline.find(params[:id])
    @guideline.destroy
   @guideline.create_activity :destroy, owner: current_user


    respond_to do |format|
      format.html { redirect_to guidelines_url }
      format.json { head :no_content }
    end
  end

def update

    @guideline = Guideline.find(params[:id])
    if @guideline.update_attributes(params[:guideline])
     @guideline.create_activity :update, owner: current_user
    end

def create
    @guideline = current_user.guidelines.new(params[:guideline])
    if @guideline.save
      @guideline.create_activity :create, owner: current_user
    end

guideline.rb

include PublicActivity::Common

查看公共活动/guideline/\u destroy.html.erb

deleted a guideline 
<% if activity.trackable %>
    <%= link_to activity.trackable.title, activity.trackable %>
<% else %>
    which can no longer be viewed
<% end %>

rails日志说

也许您可以尝试在关联中设置：autosave=>true。例如：

class User < ActiveRecord::Base  # or wherever location the guidelines association is being set
  has_many :guidelines, :autosave => true
 ...
end

谢谢-我可以把它添加到users.rb有很多：指南，：autosave=>true，但这没有任何区别，抱歉，回到你以前的建议。它确实阻止了这个错误消息的出现，但是“删除指南”并没有添加到我的可跟踪活动反馈中。你有没有找到解决方法？最后，我将@guideline.create_活动：destroy，所有者：current_用户移动到@guideline.destroy之前，使其正常工作。我不喜欢这种情况，以防破坏实际上没有通过。我也有这个问题，你解决了吗？比如@jameswilliamiii，我不喜欢在交易前调用create_活动。奇怪的是，这里似乎有用：
