Models

In MVC frameworks models are responsible for the database interaction logic. Go-Web takes advantage of the GORM library to provide them (see GORM documentation for more information about models).

You can create a new model by running the following command:

$> ./alfred model:create [model name]

note

Models generated with the model:create command are located in the database/model folder.

danger

Every model has to be registered in the foundation.BaseEntities structure located in the register/register.go. Alfred take care of this for you, but if you want to create a model manually you have to do it manually.

Registrazione di un nuovo modello

// Other BaseEntities structs...
//
// Models will handle all application models
// Here is where you've to register your custom models
// If you create a new model with Alfred it will be auto-registered
Models: register.ModelRegister{
  model.User{},
  // Here is where you’ve to register new models
},

Seeding

You can populate your database with test data implementing the Seed method.

tip

Go-Web uses GoFakeIt library to generate fake data.

Seeding method of a model

// Execute model seeding
func (User) Seed(db *gorm.DB) {
    for i := 0; i < 10; i++ {
        password := gofakeit.Password(true, true, true, true, false, 32)
        encryptedPassword, _ := bcrypt.GenerateFromPassword([]byte(password), 14)

        user := User{
            Name:     gofakeit.FirstName(),
            Surname:  gofakeit.LastName(),
            Username: gofakeit.Username(),
            Password: string(encryptedPassword),
        }

        if err := db.Create(&user).Error; err != nil {
            exception.ProcessError(err)
        }
    }
}

Seeder may be executed by running the command ./alfred database:seed [model name].

danger

Omitting the model name the command will run every model seeder's.
