What does an Auction object represent? It may help to tell us some of
the attributes of Auction to give us a better understanding. Having
answered that the question is how many bids are associated with an
auction? If the answer is many then it you must use auction has many
bids, otherwise it would only be able to be associated with one bid.

Is the current price the highest of the prices in the bids? In which
case you should probably not store the current price at all, but work
it out when needed from the associated bids. Only have it stored
separately if it becomes a performance issue as it will likely
complicate the code significantly.
