协会不使用测试条目 [英] Associations not working with test entries

问题描述

我在GORM中定义了两个模型User和Address:档案user.go

I have two models User and Address in GORM defined: File user.go

type User struct {
    gorm.Model
    Identity     string    `json:"identity"`
    Password     string    `json:"password"`
    Address      Address
    AddressID    int
}

type Address struct {
    gorm.Model
    Street       string `json:"street"`
    StreetNumber string `json:"streetnumber"`
}

在main.go文件中，我启动数据库，自动迁移并想向数据库添加测试用户:

In the main.go file I initiate the DB, automigrate and want to add a test user to the DB:

database.InitDatabase()

database.DBConn.AutoMigrate(&user.User{})
database.DBConn.AutoMigrate(&user.Address{})

userRec := &user.User{ Identity: "John Wayne", Password: "mysecretpassword", Address: user.Address{Street: "Teststreet", StreetNumber: "1"}}

database.DBConn.Create(userRec)

也将创建用户和地址，但是，该地址与该用户没有关联，只是空的地址字段出现.我忘记了什么?

The user gets created and the address as well, however, the address is not associated with the user, just empty Address fields come up. What did I forget?

如果您的实体中有关联(使用嵌套模型)，这是设置测试条目的正常方法吗?

Is this the normal way to setup a test entry if you have associations in your entities (with nested models)?

推荐答案

尝试使用"address_id"字段作为 foreignKey .

Try using the "address_id" field as a foreignKey.

例如

type User struct {
    gorm.Model
    Identity     string     `json:"identity"`
    Password     string     `json:"password"`
    Address      Address    `gorm:"foreignKey:address_id;association_autoupdate:false"`
    AddressID    uint       `json:"address_id"`
}
