🍂 Model 写法​

protected $fillable = [

    ];
    
//如果没有写，系统会默认变成products
public $table = "product";
    
//不要使用就写
public $timestamps = false;

🍂 Migration 写法​

$table->id();
$table->bigIncrements('id'); // 大整数自增字段
$table->string('name');
$table->boolean('is_active');
$table->char('code', 10); // 固定长度的字符串
$table->date('start_date');
$table->dateTime('created_at');
$table->time('meeting_time');
$table->timestamp('last_updated');
$table->decimal('price', 8, 2);
$table->float('discount', 5, 2);
$table->enum('gender', ['male', 'female']);
$table->integer('quantity');
$table->bigInteger('total'); // 不会受到普通整数类型的数值范围限制
$table->text('description'); // 适用于较小的文本内容
$table->longText('full_text'); // 用于较大的文本内容
$table->uuid('uuid');
$table->foreignId('user_id')->constrained(); // 用于指定该外键与另一张表的关联关系。
$table->foreignId('creator_id')->constrained('users');
$table->foreign('user_id')->references('id')->on('users');

->nullable()
->unique()
->nullable()->unique()
->default('active')
->unsigned() //零和正数，而不允许负数
->onDelete('cascade')
->foreign('service_category_id')->references('id')->on('service_categories')->onDelete('cascade')
