AutoMigrate重复创建唯一索引？

[congjunhua]

Your Question

type User struct {
    gorm.Model
    PublicID uint `gorm:"type:char(10);not null;unique"`
}

db.AutoMigrate(&User{})

为什么这样子写法每次重新运行程序时MySQL都会增加一个键和索引呢？

-- key
public_id
public_id_1
public_id_2
public_id_3
...

-- unique
public_id
public_id_1
public_id_2
public_id_3
...

直到报Error 1069: Too many keys specified; max 64 keys allowed错误。

将 unique 换成 uniqueIndex 。
