Laravel更新数据库表设计

我有一个php laravel projekt,我需要在一个/多个模型中添加一个字段(Eloquent)。我没有太多的PHP经验,也从未尝试过laravel。

该课程现在看起来像这样

class Player extends Eloquent
{
use GenderTrait;
use VisibilityTrait;
use PlayerPhotoTrait;
use PlayerActionTrait;

const GENDER_MALE = 2;
const GENDER_FEMALE = 1;

/**
 * The database table used by model.
 *
 * @var string
 */
protected $table = 'players';

/**
 * Parameters for `actions` relation.
 *
 * @see PlayerActionTrait::actions()
 * @var array
 */
protected $actionModel = [
    'name' => 'PlayerAction',
    'foreignKey' => 'player_id',
];

/**
 * The list of mass-assignable attributes.
 *
 * @var array
 */
protected $fillable = [
    'name',
    'start_value',
    'gender',
    'is_visible',
    'nation',
];

/**
 * The list of validation rules.
 *
 * @var array
 */
public static $rules = [
    'name' => 'required',
    'nation' => 'required|numeric',
    'start_value' => 'required|numeric',
];

/**
 * @inheritdoc
 */
protected static function boot()
{
    parent::boot();

}

/**
 * Players country.
 *
 * @return Country
 */
public function country()
{
    return $this->belongsTo('Country', 'nation');
}

/**
 * Player videos.
 *
 * @return mixed
 */
public function videos()
{
    return $this->morphMany('YoutubeLink', 'owner');
}
}

我想添加一个名为“level”的字符串字段,但我不知道如何去做。如果我首先在MySQL中创建字段然后模型更新,如果我更新模型然后Laravel为我更新MySQL?

我期待听到我能做些什么:)

您需要添加迁移:

php artisan make:migration add_fields_to_players_table --table=players

/database/migrations新迁移中打开并撰写

Schema::table('players', function ($table) {
    $table->string('new_string_field');
});

现在您需要运行迁移

php artisan migrate
