和Game
每个游戏都包含两个团队。所以我还有一个模型 - Team
。它有game_id,team_id和其他字段,作为赢家和详细分数。
我想在一个页面中显示许多游戏,所以我写TeamParticipate
然后,我想在页面上显示参与每个游戏的每两个命令:
@games = Game.where(some_query).includes(:team_participates)
我为页面上的每个团队提供aditional select查询。有没有办法解决这个问题,并通过3个查询加载页面:
-@games.each do |game|
=game.date
-game.team_participates.each do |tp|
=tp.team.title
答案 0 :(得分:1)
Game.includes(team_participates: :team).where(.....)
将会这样做。
