toArray() 中缺少惰性急切加载关系

Question

拉拉维尔 5.8

我懒惰地加载与相关客户的用户，该客户与 crmaccount 对象具有一对一关系

\n\n

这些模型正在工作，因此当我检索急切加载的实体时，它会显示所有嵌套关系。

\n\n

一行之后，我在该对象上使用“toArray()”方法，并且输出缺少第三级关系。

\n\n

关于“crmaccount”模型的唯一特殊之处可能是它包含一个必须转换的 json 列。

\n\n

知道这是怎么回事吗？

所有这些都发生在中间件中。如果我使用 with 或 load 没有区别。

\n\n

public function handle($request, Closure $next)\n{\n    $UserData = \\Auth::user();\n    if($UserData){\n        $User = \\App\\Login::with([\'role\',\'customer\',\'customer.crmaccount\'])->find($UserData->id);\n        dump($User);\n        dd($User->toArray());\n\n\n        $UserData[\'isAdmin\'] = false;\n        if($UserData[\'role\'][\'name\'] === \'Admin\'){\n            $UserData[\'isAdmin\'] = true;\n        }\n        $request->request->add([\'UserData\' => $UserData]);\n    }\n\n    return $next($request);\n}\n

每个模型上都有一个protected $visible = [];和protected $hidden = []属性。object这些控制模型转换为,array或 时可用的属性json。这包括relationships，因为 Laravel 在内部将它们转换为属性，因此从 中省略它们visible或将它们包含在内hidden将导致它们不可用。

在Customer.php：

protected $visible = ['id','name'];

由于crmaccount不在该数组中，因此只有id和name可用。只需添加crmaccount到数组即可处理：

protected $visible = ['id','name', 'crmaccount'];

或者，使用hidden显式设置您不想显示的属性，并且relationship，如果通过加载，->with()将默认显示。
