Question

I currently have a Game model with a list of Player objects…

has_many :players, :dependent => :destroy

…and I have the following statement to return the name and id of all Game objects in my DB…

self.connection.select_all("select id, name from games")

…how can I include the player count for each game, along with the id and name?

Thanks so much in advance for your wisdom!

Answer 1

I think this should work:

self.connection.select_all("SELECT games.id, games.name, COUNT(players.id) AS player_count FROM games LEFT JOIN players ON games.id=players.game_id GROUP BY games.id")
