您如何在Golangs Gorm中进行UUID? [英] How do you do UUID in Golangs Gorm?

问题描述

我有以下型号...

type User struct {
    ID        string  `sql:"type:uuid;primary_key;default:uuid_generate_v4()"`
    FirstName string `form:"first_name" json:"first_name,omitempty"`
    LastName  string `form:"last_name" json:"last_name,omitempty"`
    Password  string `form:"password" json:"password" bindind:"required"`
    Email     string `gorm:"type:varchar(110);unique_index" form:"email" json:"email,omitempty" binding:"required"`
    Location  string `form:"location" json:"location,omitempty"`
    Avatar    string `form:"avatar" json:"avatar,omitempty"`
    BgImg     string `form:"bg_img" json:"bg_img,omitempty"`
    CreatedAt time.Time
    UpdatedAt time.Time
    DeletedAt time.Time
}

我尝试了几种不同的方式，但是这种方式会抛出(pq:关系用户"不存在).我没有相关的模型，实际上只是一个模型.

I've tried several different ways, but this way throws (pq: relation "users" does not exist). I have no related models, it's literally just that one model.

我尝试使用...

func (user *User) BeforeCreate(scope *gorm.Scope) error {
    scope.SetColumn("ID", uuid.NewV4())
    return nil
}

带有一个uuid lib，但也没有运气.

Along with a uuid lib, but had no luck with that either.

推荐答案

原来，我正在尝试将UUID存储为错误的类型，我在这样做...

Turns out I was trying to store the UUID as the wrong type, I was doing...

func (user *User) BeforeCreate(scope *gorm.Scope) error {
    scope.SetColumn("ID", uuid.NewV4())
    return nil
}

何时需要...

func (user *User) BeforeCreate(scope *gorm.Scope) error {
    scope.SetColumn("ID", uuid.NewV4().String())
    return nil
}
