Laravel-没有显示直接插入记录的问题，但保存在应用程序上的记录显示“尝试获取非对象错误的属性”

Question

我正在laravel 中构建我的第一个项目：一个家谱。我有一个sql 脚本来插入我现有的记录（db 是postgres），并且我将有表格来添加/更新记录。

我看到了一个奇怪的错误。我正在使用家庭的基本路线/模型绑定（没什么花哨的），我可以查看所有家庭记录的索引，显示一个的信息，编辑一个的信息等。所有这些都适用于我的记录使用我的 sql 脚本插入，几乎 对于我使用应用程序新创建的记录，所有这些都可以正常工作：新记录出现在索引中，我可以对其进行编辑（例如：families/5/edit） ，但是当我尝试查看信息时（例如：families/5），我收到“尝试获取非对象的属性”错误（请参阅本文末尾的完整堆栈跟踪） .

我的第一个想法可能是一条冲突的路线，但我只有这个（所有其他路线都使用不同的词）：

Route::resource('families', 'FamilyController');

store方法就是：

public function store(SaveFamilyRequest $request)
{
    $this->createFamily($request);
    return redirect('families');
}

我的 SaveFamilyRequest 具有确保 5 个必填字段存在的规则（但新记录已添加到数据库中，因此必须通过才能存储记录）。

控制器中的显示功能只显示带有该对象的显示视图：

   public function show(Family $family)
    {
        return view ('family.show', compact('family'));
    }

显示视图只是尝试显示 {{$family}} 对象的所有内容

当我查看数据库中的记录时，一切看起来都很好（我从我的应用程序中保存的字段较少，但我跳过的字段都是可以为空的）。

有趣的是我对Person 记录有完全相同的设置，并且对于那些页面（包括显示视图），对于导入的人员记录和我添加到应用程序。

我还应该看什么？

提前感谢任何帮助/线索！

（经过一天的各种更改，同一个视图不再抛出之前的错误，所以我关闭了这个问题，以免其他人浪费时间）
