Question

我有一个问题，我试图更新帖子中相同类型的多个模型。循环中的第一个模型得到更新，但其余的不是出于某种原因。

我已经发布了服务器日志，您可以在其中查看并更新第一个模型，然后查找其余模型。

有没有人对我的问题有什么想法？感谢

  def special_save
    temp = params["_json"]

    temp.each { |h|
      hh = h['h_w']

      h_w = HourWorking.find(hh[:id])

      hh.delete('id')

      h_w.update_attributes(hh)
    }
  end   



HourWorking Load (2.5ms)  SELECT "hour_workings".* FROM "hour_workings" WHERE ("hour_workings"."id" = 187) LIMIT 1
SQL (1.2ms)  BEGIN
SQL (3.7ms)   SELECT a.attname, format_type(a.atttypid, a.atttypmod), d.adsrc, a.attnotnull
FROM pg_attribute a LEFT JOIN pg_attrdef d
ON a.attrelid = d.adrelid AND a.attnum = d.adnum
WHERE a.attrelid = '"hour_workings"'::regclass
AND a.attnum > 0 AND NOT a.attisdropped
ORDER BY a.attnum
SQL (1.7ms)  UPDATE "hour_workings" SET "end_time" = '2000-01-01 04:45:00.000000', "start_time" = '2000-01-01 01:45:00.000000', "updated_at" = '2011-02-10 10:18:19.955198' WHERE ("hour_workings"."id" = 187)
SQL (4.3ms)  COMMIT
HourWorking Load (1.7ms)  SELECT "hour_workings".* FROM "hour_workings" WHERE ("hour_workings"."id" = 169) LIMIT 1

Answer 1

尝试删除：id键

hh.delete(:id)

Answer 2

啊我发现了我的问题。

我遇到的问题是，我发布的params是数据库中已有内容的精确副本。
