Question

How Do I use redirect and pass an object to the edit action? The following code does not work:

  def edit
    @promotion = Promotion.find_by_id(@params['promo_id']) 
  end

  def update
    promotion = Promotion.find(params[:promotion_profile][:promotion_id])
       promo_perfil = promotion.profile

       if promo_perfil.update_attributes(params[:promotion_profile])

         redirect_to admin_edit_path(promotion.id => @params[:promo_id])
       else
   end

Answer 1

The edit action is looking for params['promo_id'] (why @params['promo_id']?).

So pass :promo_id this way:

redirect_to admin_edit_path(:promo_id => promotion)
