Rails 7.2 用符号打破 find_by

Question

我正在将 Rails 应用程序从

7.1.3.2

升级到

7.2.1,

，但我遇到了

find_by.

的问题

在我的控制器中，我有

ControlPlan.find_by("code = :code AND validity_dates @> date :date",
                    code: hash_params[:control_plan_code],
                    date: hash_params[:inspection_started_on])

在

7.1.3.2

中运行良好，但在升级后会生成错误。该问题与

validity_dates

的插值有关。

如下控制台所示，如果我使用字符串作为日期，则查询可以工作，但如果我使用符号，即使生成的 SQL 看起来相同，也会收到错误。

s(dev)> ControlPlan.where("validity_dates @> date '2020-12-24'").to_sql
=> "SELECT \"control_plans\".* FROM \"control_plans\" WHERE (validity_dates @> date '2020-12-24')"
s(dev)> ControlPlan.where("validity_dates @> date '2020-12-24'")
  ControlPlan Load (4.3ms)  SELECT "control_plans".* FROM "control_plans" WHERE (validity_dates @> date '2020-12-24') /* loading for pp */ LIMIT $1  [["LIMIT", 11]]
=> []
s(dev)> ControlPlan.where("validity_dates @> date :date", date: "2020-12-24").to_sql
=> "SELECT \"control_plans\".* FROM \"control_plans\" WHERE (validity_dates @> date '2020-12-24')"
s(dev)> ControlPlan.where("validity_dates @> date :date", date: "2020-12-24")

我检查了Rails 7.2发行说明，但我没有发现任何相关内容。

我可以按如下方式更新我的代码，但我宁愿保持现在的样子。

ControlPlan.find_by("code = :code AND validity_dates @> date '#{hash_params[:inspection_started_on]}'",
                    code: hash_params[:control_plan_code])

我在这里缺少什么？

Answer 1

ControlPlan.find_by("code = :code AND validity_dates @> date :date",
                    code: hash_params[:control_plan_code],
                    date: Arel::Nodes.build_quoted(hash_params[:inspection_started_on]))
