Question

我的OffersController：

中有基本的商店功能

public function store(Request $request)
{     
    $offer = new Offer;
    $offer->title = $request->title;
    $offer->body = $request->body;
    $offer->region = $request->region;
    $offer->user_id = auth()->user()->id; 

    $offer->save();

    $offer->specialities()->sync($request->specialities, false); 

    return response()->json([
        'created' => true
    ], 201);
}

我的api请求正在使用如下对象调用OffersController存储函数：

{ "title": "offer title", "body": "offer body", 
"specialities": { "lang": "en", "id": "eu33", "icon": "0",
"name": "speciality name 33" }, "region": "region1" }

这给了我一个错误：Internal Server Error

"message": "SQLSTATE[HY000]: General error: 1366 Incorrect 
integer value: 'pl' for column 'speciality_id' at row 1 (SQL: 
insert into `offer_speciality` (`offer_id`, `speciality_id`) 
values (59, en))",

所以我似乎犯了明显的错误，所以我更正了我的要求：

$offer->specialities()->sync($request->specialities->id, false);

这给了我一个错误：

Internal Server Error, Trying to get property of non-object.

我在这里做错了什么？

编辑：表架构：

    Schema::create('offers', function (Blueprint $table) {
        $table->increments('id');
        $table->string('title');
        $table->string('region');
        $table->mediumText('body');
        $table->integer('user_id');
        $table->timestamps();
    });

    Schema::create('specialities', function (Blueprint $table) {
        $table->increments('id');
        $table->string('name');
        $table->timestamps();
    });

    Schema::create('offer_speciality', function (Blueprint $table) {
        $table->increments('id');
        $table->integer('offer_id')->unsigned();
        $table->integer('speciality_id')->unsigned();
    });

Answer 1

$request->specialities是数组，因此要访问您说$request->specialities['id']

的ID

Answer 2

specialities没有从数据库记录中自动保存，只有在相应地设置路径时才会发生模型绑定。

看来你没有使用specialties表主键的无符号整数，给定"id": "eu33"，这是正确的吗？

首先尝试使用json_decode($request->get('specialties'));然后同步到优惠。

这里只是猜测，但也首先查询specialities记录，如：

$offer->save();

$specialties = DB::table('specialties')->where('name', $request->get('specialties')['name'])
                                       ->first();

$offer->specialities()->sync($specialities->id, false);

很难说没有看到你的架构。
