Public_activity deleting - ruby-on-rails

Question

I have public_activity working on my rails app for the guidelines model. But there is a problem with deleting a guideline. Updating and creating guidelines are fine.
The error says
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
view 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 %>
the rails log says

Perhaps you could try setting :autosave => true in your association. For instance:
class User < ActiveRecord::Base # or wherever location the guidelines association is being set
has_many :guidelines, :autosave => true
...
end
