Hi Guys, I'm trying to come up with a model layout for a simple enough race prediction app but am a little stuck. Basically, the app will allow users to enter their predictions for a number of races (20 races in total). When the races have been finished, I want to determine who predicted all of the race winners correctly, who got 19/20, who got 18/20 etc.
Here's a summary of the players and their relationships: A User has one Betslip. A Betslip has many Predictions (one Prediction for each of the 20 races). Each Prediction consists of one Race and one Racer (the predicted-to-win Racer). Each Race has a number of Racers. Each Race has one Winner (also a Racer). This is where I'm getting a little confused. Each Prediction consists of one Race and one Racer, but a Race also consists of a number of Racers. A Race will also have one Winner (also a Racer). It seems like there are three types of Racers - a general racer (linked to a race), a predicted-to-win racer (linked to a prediction) and a winning racer (linked to a race). Would anyone have any advice on the best way to model this? At the end of all of the races, the main thing I want to do is compare each user's betslip against the actual winners to see how many of their predictions were correct.
