我如何遍历这个关联数组并将其保存到数据库中？

Question

我有这个请求以这种格式进入服务器，我如何将它保存到数据库中，我是 Laravel 的新手，而且我有三个模型，Trip（存储前 4 个键值对的地方），Location（存储源和目标数组的位置），然后将类别存储在类别模型中

{
    "name": "glass cup",
    "weight" : "12kg",
    "quantity": 400,
    "source": {
         "longitude":122324,
         "latitude":231242,
         "address": "this is just a new address",
         "place_id":23234
    },
    "destinations": [
        {
             "longitude":122324,
             "latitude":231242,
             "address": "this is just a new address",
             "place_id":23234
        },
        {
            "longitude":122324,
            "latitude":231242,
            "address": "this is just a new address",
            "place_id":23234
        },
        {
            "longitude":122324,
            "latitude":231242,
            "address": "this is just a new address",
            "place_id":23234
        }
    ],
    "categories": ["food", "clothes", "utensils"]

}

要么将其保存为 JSON，要么创建适当的文件以插入数据库。另外，不知道表之间是否有任何关系，但是要插入数据，您可以执行以下操作：

$trip = new \App\Models\Trip;
$trip->name = $request->name;
$trip->weight = $request->weight;
$trip->quantity = $request->quantity;
$trip->save();

对于目的地，您只需循环项目：

foreach ($request->destinations as $dest)
{
    $location = new \App\Models\Location;
    $location->longitude = $dest->longitude;
    $location->latitude = $dest->latitude;
    $location->address = $dest->address;
    $location->place_id = $dest->place_id;
    $location->save();
}

如果您想将trip id 保存在location 表中，只需使用$location->trip_id = $trip->id;
