gorm 与 foreignKey 引用有很多关系

Question

我的目标是存档与 gorm 的“有很多”关系

我不想生成任何 ID，所以我故意没有在我的结构中使用 gorm.Model

我将两个结构设置为：

type Application struct {
  Name         string        `json:"name" gorm:"primaryKey"`
  Description  string        `json:"description"`
  Translations []Translation `json:"titles" gorm:"foreignKey:ApplicationName;references:Name"`
}

type Translation struct {
  ApplicationName string `json:"applicationName" gorm:"primaryKey"`
  Locale          string `json:"locale" gorm:"primaryKey"`
  Value           string `json:"value"`
}

Translation.ApplicationName 应该是 Applications

的外键

(Translation.ApplicationName + Translation.Locale) Translations

的主键

创建应用程序后

{
  "name" : "postedApplication1",
  "description" : "postedDescription3",
  "titles" : [
    {
        "locale": "de-DE",
        "value":"deutsch"
    },
     {
        "locale": "de-AT",
        "value":"AT"
    }
  ]
}

我收到以下错误

ON CONFLICT clause does not match any PRIMARY KEY or UNIQUE constraint [0.065ms] [rows:0] INSERT INTO translations (application_name,locale,value) VALUES ("postedApplication1","de-DE","deutsch"),("postedApplication1","de-AT","AT") ON CONFLICT (application_name,locale) DO UPDATE SET application_name=excluded.application_name

和

ON CONFLICT clause does not match any PRIMARY KEY or UNIQUE constraint [0.531ms] [rows:0] UPDATE applications SET description="postedDescription3" WHERE name = "postedApplication1" [GIN] 2021/08/27 - 11:23:00 | 200 | 841.953µs | 127.0.0.1 | POST "/applications"

有人知道我做错了什么

Answer 1

已解决 qx.X,p

一切正确！

安装 vscode-sqlite 并检查数据库后，我发现 sqlite 表与我设计的不一样

问题是 AutoMigrate 由于在开发过程中发生了很多变化而产生了无效状态

database.AutoMigrate(&models.Application{}, &models.Translation{})

我必须删除 sqlite“gorm.db”文件并重新启动应用程序

gorm 与 foreignKey 引用有很多关系

gorm has many relation with foreignKey reference

go

go-gorm

go-gin
