CRUD operations with GORM

In previous chapters, whenever we wanted to create an entry in the database, we had to write a SQL statement that inserts the data into the table, but that is no longer needed; GORM takes care of all that for us. Let’s start creating a new user using our GORM model.

Creating a user

To create a new user, we simply create an instance of our model and call the Create method:

user := User{
  Username: "johndoe",
  Password: "password123",
  Role: "user",
}
result := db.Create(&user)
if result.Error != nil {
  log.Fatal(result.Error)
}
