我有 public_activity 在我的 rails 应用程序上为指南模型工作。但是删除指南存在问题。更新和创建指南很好。

错误说

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

指南控制器.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

指南.rb

include PublicActivity::Common

查看 public_activity/guideline/_destroy.html.erb

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

也许您可以尝试:autosave => true在您的关联中进行设置。例如：

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