go-gorm, postgres: simple inserts return error

I'm trying to do simple inserts, trying to evaluate the usefulness of Postgres because of this recent hype. I'm a mongoDB guy. And this is what I'm trying to do:

db, e := gorm.Open("postgres", fmt.Sprintf("host=%s user=%s dbname=%s password=%s sslmode=disable", pgHost, pgUser, pgDatabase, pgPass))
if e != nil {
	log.Fatal(e.Error())
}
defer db.Close()
db.AutoMigrate(&model.Customer{}, &model.Email{}, &model.Address{}, &model.Name{}, &model.Logindata{})

name := new(model.Name)
email := new(model.Email)
customer := &model.Customer{
	Name:         name,
	PrimaryEmail: email,
}
customer.Name.First = "Darko"
customer.Name.Last = "Luketic"
customer.Name.Middle = "" // also tried without this line
customer.PrimaryEmail.Address = "my@mail.come"
customer.PrimaryEmail.Verified = true
tx := db.Begin()

if e := tx.Create(name); e != nil {
	tx.Rollback()
	log.Fatal("create name", e.Error)
}

if e := tx.Create(email); e != nil {
	tx.Rollback()
	log.Fatal("create email", e.Error)
}

if e := tx.Create(customer); e != nil {
	tx.Rollback()
	log.Fatal("create customer", e.Error)
}

tx.Commit()

with the models being

package model

import "github.com/jinzhu/gorm"

type Customer struct {
	gorm.Model
	Name            *Name
	BillingAddress  *Address
	ShippingAddress *Address
	PrimaryEmail    *Email
	AlternateEmails []*Email
	Logindata       *Logindata
}

type Name struct {
	gorm.Model
	First  string `json:"first"`
	Middle string `json:"middle"`
	Last   string `json:"last"`
}

type Logindata struct {
	gorm.Model
	Username string
	Password []byte
}

type Email struct {
	gorm.Model
	Address  string
	Verified bool
}

type Address struct {
	gorm.Model
	Address1 string
	Address2 string
	City     string
	Code     string
	Country  string
}

The output:

go run main.go migrate
migrate called
2017/08/01 17:10:26 create name<nil>
exit status 1

What am I doing wrong?
Why is there no error message?
How do I fix it?

According to the docs, Create returns a *DB, not an error. So your code should be more like

if tx = tx.Create(name); tx.Error != nil { /* ... */ }

Also, additionally,

db, e := gorm.Open("postgres", fmt.Sprintf("host=%s user=%s dbname=%s password=%s sslmode=disable", pgHost, pgUser, pgDatabase, pgPass))
if e != nil {
	log.Fatal(e.Error())
}
defer db.Close()
db.AutoMigrate(&model.Customer{}, &model.Email{}, &model.Address{}, &model.Name{}, &model.Logindata{})

name := new(model.Name)
email := new(model.Email)
customer := &model.Customer{
	Name:         name,
	PrimaryEmail: email,
}
customer.Name.First = "Darko"
customer.Name.Last = "Luketic"
customer.Name.Middle = ""
customer.PrimaryEmail.Address = "my@mail.come"
customer.PrimaryEmail.Verified = true
tx := db.Begin()

if e := tx.Create(customer).Error; e != nil {
	tx.Rollback()
	log.Fatal("create customer", e)
}
tx.Commit()

I need to change the structs so they have a related field. I did expect more from an orm. That's why it's an ORM object relationship manager.
gorm doesn't manage much there

package model

import "github.com/jinzhu/gorm"

type Customer struct {
	gorm.Model
	Name            *Name
	BillingAddress  *Address
	ShippingAddress *Address
	PrimaryEmail    *Email
	AlternateEmails []*Email
	Logindata       *Logindata
}

type Name struct {
	gorm.Model
	CustomerID uint
	First      string `json:"first"`
	Middle     string `json:"middle"`
	Last       string `json:"last"`
}

type Logindata struct {
	gorm.Model
	CustomerID uint
	Username   string
	Password   []byte
}

type Email struct {
	gorm.Model
	CustomerID uint
	Address    string
	Verified   bool
}

type Address struct {
	gorm.Model
	CustomerID uint
	Address1   string
	Address2   string
	City       string
	Code       string
	Country    string
}

note the CustomerID uint
