先创建模型层以及迁移的表

php artisan make:model Models/User -m

　　字段

$table->bigIncrements('id');
            // 角色
            $table->unsignedInteger('role_id')->default(0)->comment('角色ID');

            $table->string('username',50)->comment('账号');
            $table->string('truename',50)->default('未知')->comment('真实姓名');
            $table->string('password',255)->comment('密码');
            // nullable 可以为null
            $table->string('email',50)->nullable()->comment('邮箱');
            $table->string('phone',15)->default('')->comment('手机号码');
            $table->enum('sex',['先生','女士'])->default('先生')->comment('性别');
            $table->char('last_ip',15)->default('')->comment('登录IP');
            $table->timestamps();
            // 软删除 生成一字段  deleted_at 字段
            $table->softDeletes();

     执行迁移

php artisan migrate

　 创建用户的数据填充文件

php artisan make:seeder UserSeeder

　 生成一个数据工厂

php artisan make:factory UserFactory -m Models/User

　 auth

//模型层
use Illuminate\Foundation\Auth\User as AuthUser;
//database factories
use Faker\Generator as Faker;
 'username' => $faker->userName,
            'truename' => $faker->name(),
            'password' => bcrypt('admin888'),
            'email' => $faker->email,
            'sex' => ['先生','女士'][rand(0,1)]

　　数据填充修改

 User::truncate();
        //添加模拟数据  100用户
        factory(User::class,200)->create();
        User::where('id',1)->update(['username'=>'admin']);

　　修改时调用

$this->call(User::class);
