Title Body

So I have a method in a reservation model called add_equip. This method does some checking to make sure the added piece of equipment is valid (not conflicting with another reservation). The checks work. If a added piece of equipment shouldn't be added it isn't, and if it should it is. The problem is I can't figure out how to send the messages back up to the controller to be put in the flash message? I know I must be missing something here, but I've googled for a few hours now and can't really find any clear explanations how how to pass errors back up the the controller, unless they are validation errors. add_equip in reservations_controller def add_equip @reservation = Reservation.find(params[:id]) @addedEquip = Equip.find(params[:equip_id]) respond_to do |format| if @reservation.add_equip(@addedEquip) flash[:notice] = "Equipment was added" format.html { redirect_to(edit_reservation_path(@reservation)) } else flash[:notice] = @reservation.errors format.html { redirect_to(edit_reservation_path(@reservation)) } end end end add_equip in reservation model def add_equip equip if self.reserved.find_by_equip_id(equip.id) self.errors.add_to_base("Equipment Already Added") return false elsif !equip.is_available?(self.start, self.end) self.errors.add_to_base("Equipment Already Reserved") return false else r = Reserved.new r.reservation = self r.equip = equip r.save end end Any help would be greatly appreciated. I know I'm missing something basic here.
