How to write a migration to add not null in table field GOLANG
问题
我想修改User模型中的一个列。
type User struct {
gorm.Model
Email string `gorm:"unique;type:varchar(50)"`
Password string
Active bool
FirstName string `gorm:"type:varchar(10)"`
LastName string `gorm:"type:varchar(10)"`
Age int
Gender bool `gorm:"type:boolean"`
MaritalStatus bool `gorm:"type:boolean"`
Address string `gorm:"type:varchar(10)"`
City string `gorm:"type:varchar(10)"`
State string `gorm:"type:varchar(10)"`
Country string `gorm:"type:varchar(10)"`
ContactNoOne string `gorm:"type:varchar(13)"`
ContactNoTwo string `gorm:"type:varchar(13)"`
}
我想将Email字段设置为非空。如何编写迁移来实现这个目标？

在标签gorm上添加not null
type User struct {

Email string `gorm:"unique;type:varchar(50);not null"`
...
}

编辑你的模型，然后使用AutoMigrate函数。
db.AutoMigrate(&User{})
文档：https://gorm.io/docs/migration.html
英文:
Edit your model, then us AutoMigrate
db.AutoMigrate(&User{})
