class Team < ApplicationRecord
end
class Game < ApplicationRecord
belongs_to :winner, class_name: 'Team'
belongs_to :loser, class_name: 'Team'
end
Thanks in advance. Is it possible to write a dependence for destroy a belonged Game
instance when a Team
instance is destroyed? I didn't find anything on it, all things, I tried, like
class Team < ApplicationRecord
has_many :games, inverse_of: :winner, dependent: :destroy
...
didn't work.
CodePudding user response:
You need to add foreign keys
class Team < ApplicationRecord
has_many :winner_games, foreign_key: :winner_id, class_name: 'Game', dependent: :destroy
has_many :loser_games, foreign_key: :loser_id, class_name: 'Game', dependent: :destroy
end
