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.ModelEmail string `gorm:"unique;type:varchar(50)"`Password stringActive boolFirstName string `gorm:"type:varchar(10)"`LastName string `gorm:"type:varchar(10)"`Age intGender 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{})
