[PHP知识库]关于Laravel 8 模型关联实例

模型层

public function PlateStockInfo()
    {
        return $this->hasMany('App\Models\AppInfo30\PlateStockInfo','DetailPlateCode','DetailPlateCode');
    }

调用（多条件筛选）

$res = PlateClassInfo::with(['PlateStockInfo'=>function($query) use ($stock_msg){
            $query->where('StockCode','like',"%$stock_msg%");
            $query->orWhere('StockName','like',"%$stock_msg%");
        }]) ->where('PlateCode','=',2)
            ->where('Remark','=',1)
            ->get();
