"message": "relation \"users\" 不存在", golang

Question

我有一个用 Go 编写的 API，我有以下一组模型......

type User struct {

    gorm.Model

    ID       string `sql:"type:varchar(36);primary key"`

    Name     string

    Password string

    Email    string

    Content  []Content

    Location string

    Tracks   []Track

    Avatar   string

    BgImg    string

    Artists  []Artist

}

type Artist struct {

    gorm.Model

    ID string `sql:"type:varchar(36);primary key"`

}

type Content struct {

    gorm.Model

    ID string `sql:"type:varchar(36);primary key"`

}

type Track struct {

    gorm.Model

    ID string `sql:"type:varchar(36);primary key"`

}

在我的main.go文件中，我正在用...初始化我的数据库

drivers.DB().CreateTable(&models.User{})

drivers.DB().CreateTable(&models.Artist{})

drivers.DB().CreateTable(&models.Content{})

drivers.DB().CreateTable(&models.Track{})

但我收到错误...

我怀疑这是因为您的Artist,Content和Trackstruct 没有对 的父引用User，尽管User对它们有很多引用。此外，嵌入类型gorm.Model已经具有 ID 字段。尝试：type Artist struct {    gorm.Model    ID string `sql:"type:varchar(36);primary key"`    UserID string `sql:"type:varchar(36)"`}type Content struct {    gorm.Model    ID string `sql:"type:varchar(36);primary key"`    UserID string `sql:"type:varchar(36)"`}type Track struct {    gorm.Model    ID string `sql:"type:varchar(36);primary key"`    UserID string `sql:"type:varchar(36)"`}
