Got it working with the following:
In the Controller:
def create
@textmessage = current_user.textmessages.build(textmessage_params)
if @textmessage.save
MessageWorker.perform_at(@textmessage.date_time, @textmessage.id)
redirect_to houses_path, notice: 'Textmessage Alert Added'
else
# redirect_to house_path(@rating.house), notice: "Error: rating was not added"
redirect_to :back, alert: 'Textmessage Alert Not Added'
end
end
