关于使用haMany Relatiions存储数据 汽车可能不仅仅是画面 每张照片只能有一辆车
汽车调制解调器Car.php
class Car extends Model
{
protected $table = 'cars';
public $timestamps = true;
use SoftDeletes;
protected $dates = ['deleted_at'];
protected $fillable = array('Marque', 'Model', 'sieges', 'climatisation', 'portes', 'transmition', 'price','url','car_id');
public function cars_images()
{
return $this->hasMany(CarsImage::class);
}
CarsImage模型
class CarsImage extends Model
{
protected $table = 'cars_images';
public $timestamps = true;
use SoftDeletes;
protected $dates = ['deleted_at'];
protected $fillable = array('url');
public function cars()
{
return $this->belongsTo(Car::class);
}
}
MyController:
public function store(Request $request) {
$car = new Car;
$car->Marque = Input::get('Marque');
$car->Model = Input::get('Model');
$car->sieges = Input::get('sieges');
$car->climatisation = Input::get('climatisation');
$car->portes = Input::get('portes');
$car->transmition = Input::get('transmition');
$car->price = Input::get('price');
$img = new CarsImage;
$img->url = 'jean Luc Picard';
DB::transaction(function() use ($car, $img) {
$car = $car->save();
Car::find($car->id)->cars_images()->save($img);
});
return 'ok';
}
问题是汽车已保存并且网址也已保存但没有car_id
请帮忙吗?
答案 0 :(得分:0)
只需使用create
方法:
$car = Car::create([
'Marque' => $request->Marque,
//other fields...
]);
$image = $car->cars_images()->create([
'url' => 'jean Luc Picard'
]);
并且不要忘记在模型中使用$fillable
。
