Question

我有一个小问题，通过Activerecord查询接口写实际上是：

Gp.select("date('gps'.'created_at') as date,('users'.'name') as name, SUM('gps'.'sum_issue') as sum_issue").joins('LEFT JOIN users ON users.id = gps.user_id').where("users.ab_id = :abs_id AND users.id != 20", {:abs_id => current_user.ab_id}).group("users.name")

查询结果必须是用户名，总和和日期。如果我直接从SQLlite执行此查询，它的工作，但是 Active Record Query Interface给我

[#<Gp sum_issue: 289000>, #<Gp sum_issue: 364130>, #<Gp sum_issue: 620000>]

我如何获得姓名，日期，sum_issue并在我的助手中显示。像这样：

{
 created_at: datet,
 sum_issue: sum_issue,
 name: name
}

Answer 1

尝试

Gp.select("date('gps'.'created_at') as date,('users'.'name') as name, SUM('gps'.'sum_issue') as sum_issue").joins('LEFT JOIN users ON users.id = gps.user_id').where("users.ab_id = :abs_id AND users.id != 20", {:abs_id => current_user.ab_id}).group("users.name").first.name

如何显示查询结果Activerecord查询接口
