Rails - 希望在

Question

我首先有这个：

@shots = @team.shots.order_by_recent.limit(5)

然后我想在其他方法中使用@shots：

made = @shots.where(made: true).count
=> 5 (should be 2)

missed = @shots.where(made: true).count
=> 5 (should be 3)

生成的查询：

SELECT COUNT(DISTINCT count_column) 
FROM (SELECT  "shots"."id" AS count_column FROM "shots" 
LEFT OUTER JOIN "games" ON "games"."id" = "shots"."game_id" 
WHERE "shots"."team_id" = $1 AND "shots"."shot_area" = $2 
AND "shots"."shot_range" = $3 AND "shots"."made" = 'f' LIMIT 5) 
subquery_for_count  [["team_id", 3], ["shot_area", "Left Side Center(LC)"], ["shot_range", "24+ ft."]]

我注意到LIMIT最后应用于整个查询。我想要做的是首先将限制应用于@team.shots.order_by_recent，然后对其进行额外的查询。

换句话说： 我想将查询分成两个单独的查询。第一个查询获得5条记录：@ team.shots.order_by_recent.limit（5），第二条查询从第一个查询中选择。现在，似乎Rails会自动将这两个查询合并为一个。
