私は新しいドメインを作成し、テーブルを手動で作成しました。 テーブルには1つのレコードしか含まれていないので、唯一のレコードIDは(1)になります。Grails、レコードを取得する際のキャストエラー
レコードが存在しない場合は自動的に作成する必要がありますが、レコードを取得しようとすると常にキャストエラーが発生します。手動でレコードを手動で作成するかどうかは関係ありません。get、findなど、常にエラーになるものは何でも返されます。失敗
コード:
def int id = 1
def WtStatus wts = WtStatus.get(id)?:new WtStatus(id:1).save(failOnError:true)
ドメイン:
class WtStatus {
def prodBufferService
int weekUpdated
Date dateUpdated
def beforeInsert() {
dateUpdated = new Date()
weekUpdated = prodBufferService.getCurrentYearWeek()
}
def beforeUpdate() {
dateUpdated = new Date()
}
static constraints = {
dateUpdated nullable:true
weekUpdated nullable:true
}
static mapping = {
table 'wt_status'
version true
id column: "id", type: 'int'
}
}
テーブルの作成スクリプト:
CREATE TABLE [dbo].[wt_status](
[id] [int] NOT NULL,
[version] [bigint] NOT NULL,
[date_updated] [datetime2](7) NULL,
[week_updated] [int] NULL,
CONSTRAINT [PK__wt_statu__3213E83F77809FC6] PRIMARY KEY CLUSTERED
(
[id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]

私はあなたが言ったことに気付いたので、あなたの解決策は機能しませんでした。私はまだ同じエラーが出ます。私はIDをintと宣言し、すべてが動作するようになりました。 – larand
