如何在 GORM 中做 bytea？

Question

I have the following model:

type User struct {
    UserId    string                `sql:"primary_key;"type:bytea"`
    Username  string
    FirstName string
    LastName  string
}

I want the UserId to be type of bytea . The above doesn't work when trying to create a table:

db.CreateTable(&User{})

Answer 1

type User struct {
    UserId    string                `gorm:"primary_key;type:bytea"`
    Username  string
    FirstName string
    LastName  string
}
