Using the rename refactoring

To rename code inline: Shift+F6.

To rename code by using the Rename dialog: press Shift+F6 two times.

You can copy the following code snippet to your editor and try to rename the Position field to JobTitle. Use the previous procedure for clues about shortcuts.

package main

		import "fmt"

		type User struct {
			ID       int
			Username string
			Position string
		}

		func main() {
			u := User {
				ID:       1,
				Username: "User",
				Position: "Job position",
			}
			fmt.Printf("User details %#v\n", u)
		}

Rename refactoring for database fields

You can copy the following code snippet to your editor and try to rename the worker table to actor. Use the previous procedure for clues about shortcuts.

package main

import (

	"github.com/jmoiron/sqlx"
	"strings"
)

type User struct {
	ID        int
	firstName string
}

const (
	dsn          = "postgres://guest:guest@localhost:54332/guest?sslmode=disable"
	getUserQuery = "SELECT first_name FROM worker WHERE actor_id = 1"
)

func main() {
	db, err := sqlx.Open("postgres", dsn)
	if err != nil {
		panic(err)
	}

	err = db.Ping()
	if err != nil {
		panic(err)
	}

	firstName := []string{}
	err = db.Select(&firstName, getUserQuery)
	if err != nil {
		panic(err)
	}

	fmt.Printf("First name: %#v\n", strings.Join(firstName, ""))
}

Renaming JSON fields

	name     string
	lastName string
}

// language=json
const userJSON = `{"ID": 1, "name":  "John", "lastName": "Smith"}`

func main() {
	u := User{
		ID:       1,
		name:     "John",
		lastName: "Smith",
	}
