Public_activity刪除

Question

我有我的rails應用程序的指導模型public_activity工作。但刪除指南存在問題。更新和創建準則是好的。

錯誤說

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

guidelines_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 

視圖public_activity /準則/ _destroy.html.erb

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

也許你可以嘗試在關聯設置:autosave => true。例如：

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