Question

我有两张桌子car_category和车辆并将车辆ID设置为车辆表c_id的外键约束。现在我想将车辆添加到车辆表格中。所以我想存储车辆细节，怎么样我将fk约束添加到我的控制器？我已经设置了表格之间的关系，在汽车模型中，

class car extends Model
{
    protected $guarded = [];
    protected $table = 'car_category';

    public function vehicles()
    {
        return $this->hasMany('Vehicle');
    }
}

车型，

class Vehicle extends Model
{
    protected $guarded = [];
    protected $table = 'vehicles';

    public function cars()
    {
        return $this->belongsTo('Car');
    }
}

并存储车辆详细信息，

public function store(Request $request)
{
    $this->validate($request, [
        'vehicle_no' => 'required',
        'vehicle_company' => 'required',
        'vehicle_category' => 'required',
        'vehicle_type' => 'required',
        'vehicle_model' => 'required',
        'vehicle_capacity' => 'required',
        'vehicle_color' => 'required',
        'c_cid' => '',
    ]);

    Vehicle::create($request->all());
            return redirect()->route('vehicles.index')
                 ->with('success','Vehicle details stored successfully');
}

如何传递fk约束值？有人可以帮助我吗？

尝试在您的表单中添加汽车字段，您可以在保存车辆时获取ID

    <div class="col-md-6"> 
        <select name="c_id" class="form-control"> 
        @foreach($car as $cars) 
            <option value="{{ $cars->id }}">{{ $cars->Name }}</option> 
        @endforeach </select> 
    </div>

这里你可以获得

中的值

public function store(Request $request) {
    // here you can get the value
    $request->c_id;
}

Laravel插入具有一对多关系的记录
