Gorm field level permission is not working

I'm using gorm with postgresql and trying to create a new row on a table. Here is my postgresql table columns.

id field is primary key and postgresql gives field values with a sequence.I'm trying to create a new record on this table with read permissions only because I don't want to set this on code.

When I do this like following, I can read from database but also gorm wants to set the field and postgresql throwing exeption.

type User struct {
	Id              int        `gorm:"column:id"`
	UUID            string     `gorm:"column:uuid"`
	FirstName       string     `gorm:"column:firstname"`
	MidName         string     `gorm:"column:midname"`
	LastName        string     `gorm:"column:lastname"`
}

When I use field level permission like this, it's working on create because gorm doesn't want to set this field like expected. But this time reads aren't working.

type User struct {
	Id              int        `gorm:"-"`
	UUID            string     `gorm:"column:uuid"`
	FirstName       string     `gorm:"column:firstname"`
	MidName         string     `gorm:"column:midname"`
	LastName        string     `gorm:"column:lastname"`
}

I've tried gorm:"<-:false" gorm:"->" and gorm:"->;<-:read" but fails.

Also tried omit with this post postgres.DB.Model(models.User{}).Omit("id").Create(newUser) but still not working.

How can I achieve this? Any idea?

Thanks in advance.

Not the best choice but solved this issue with adding hook. Now it works as expected both read an write but still thinking about field level permissions.

func (u *User) BeforeCreate(tx *gorm.DB) error {
	tx.Omit("id")
	return nil
}
