Laravel 在setupCreateOperation中选择类型字段

我对Laravel背包还是新手，在创建页面时尝试提交时遇到了问题

Illumb\Database\QueryException SQLSTATE[42S22]：未找到列： 1054“where子句”中的未知列“post_types.post_id”（SQL: 从

post\u types

中选择*其中

post\u types

post\u id

=52和

post\u type

post\u id

不为空限制1）

postcrude控制器

protected function setupCreateOperation()
{
    CRUD::setValidation(PostRequest::class);

    $this->crud->addField([
        'label' => "Post Type",
        'type' => 'select',
        'name' => 'post_type_id',
        'entity' => 'postType',
        'attribute' => 'post_type_name',
        'model' => "App\Models\PostType",
    ]);

    // $this->crud->addField('post_type_id');

    $this->crud->addField([
        'label' => 'User',
        'type'  => 'relationship',

        'type'      => 'upload_multiple',
        'upload'    => true,
        'disk'      => 'uploads', // if you store files in the /public folder, please omit this; if you store them in /storage or S3, please specify it;
        // optional:
        'temporary' => 10 // if using a service, such as S3, that requires you to make temporary URLs this will make a URL that is valid for the number of minutes specified
    ]);


    /**

public function up()

    Schema::create('posts', function (Blueprint $table) {
        $table->id();
        $table->foreignId('user_id')->constrained('users', 'id');

        $table->id();
        $table->string('post_type_name', 100);
    });
}

这里的流程是，我从createpage文件开始，其中所有selecttype字段都从其相关表中获取选项

我填写了所有的现场数据

单击提交

我上面发布的错误发生了

其中Post与PostTypes具有1-1关系，请按如下方式更改Post类型模式：

public function up()
{
    Schema::create('post_types', function (Blueprint $table) {
        $table->id();
        $table->string('post_type_name', 100);
        $table->foreignId('post_id')->constrained('posts', 'id');
    });
}

因为post_类型表中没有此类列post_id
