If you already have the database defined and you want to use these tables as models in Laravel simply configure your project to use the database you want, to do this modify the values in your environment variables:
/. env
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=mibasededatos
DB_USERNAME=el_usuario_de_tu_db
DB_PASSWORD=la_clave_de_tu_usuario
Then, create your models according to the tables in your database:
php artisan make:model Employee
and finally configure each model to connect to the correct table:
app / Employee.php
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Employee extends Model {
// con lo siguiente configuras la tabla que utilizará el modelo
protected $table = 'employees';
// y con esto especificas el nombre de la llave primaria de la tabla
protected $primaryKey = 'employee_id';
// el resto del código.. por ejemplo relaciones con otros modelos
}
