Php Laravel 8数据表加载不工作（Yajra）

我正在使用Yajra Datatables来获取表中的数据

我需要显示表

认证机构的数据，其中所述表的
非官方类别id
列应显示另一个数据库表
非官方类别的
区域名称

以下是
认证机构
模型，显示其与
非官方类别
模型的关系：

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;

class Accreditors extends Model
{
    use HasFactory;
    use SoftDeletes;

    protected $table = "accreditors";

    protected $fillable = [
        'name',
        'official_category_id',
        'subcategory',
        'position',
        'photo',
    ];

    protected $dates = [
        'deleted_at',
        'created_at',
        'updated_at'
    ];

    public function nonOfficialsCategories()
    {
        return $this->belongsTo(NonOfficialsCategories::class, 'nonofficial_category_id');
    }
}

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;

class NonOfficialsCategories extends Model
{
    use HasFactory;
    use SoftDeletes;

    protected $table = "non_officials_categories";

    protected $fillable = [
        'area_number',
        'area_name',
        'subcategory',
        'is_accreditor_head',
        'is_taskforce_head',
        'is_auditor',
        'use_counter',
    ];

    protected $dates = [
        'deleted_at',
        'created_at',
        'updated_at'
    ];

    public function taskforces()
    {
        return $this->has(TaskForces::class);
    }
    public function accreditors()
    {
        return $this->has(Accreditors::class);
    }
}

以下是

<?php

以下是数据表的当前（和错误）显示：

__________________________________________________________________________
|name     |area name        |subcategory     |position      |actions     |
__________________________________________________________________________
|         |1 //wrong        |                |              |            |
__________________________________________________________________________
|         |2 //wrong        |                |              |            |

__________________________________________________________________________

其中，显示器应为：

__________________________________________________________________________
|name     |area name        |subcategory     |position      |actions     |
__________________________________________________________________________
|         |Area I //right   |                |              |            |
__________________________________________________________________________
|         |Area II //right  |                |              |            |
__________________________________________________________________________
|         |Area III //right |                |              |            |
__________________________________________________________________________

我的错误可能是：


模型文件的雄辩关系错误
脚本
部分的
列
数组中的
.blade
部分的语法声明错误
对于
AuthoritorsController
，在
indexDatatables
方法上的语法声明错误

谢谢。
在检查我的错误后，我找到了解决办法

我需要在
indexDatatables（）
上添加另一个
addColumn（）
API:

然后我可以在
.blade
文件的
脚本部分使用以下行：

// format {data: 'name_parameter_in_add_column', name: 'relationshipName.column_name_to_be_searched'},

{data: 'area_name', name: 'nonOfficialsCategories.nonofficial_category_id'},

// the 'area_name' in the script section should be the same name declared in the first parameter of the "addColumn()" API



现在，我仍然可能在关系声明上出错，因为我仍然对
belongsTo（）/belongsToMany（）
API的用法感到困惑。如果有人能纠正我，我将不胜感激

// format {data: 'name_parameter_in_add_column', name: 'relationshipName.column_name_to_be_searched'},

{data: 'area_name', name: 'nonOfficialsCategories.nonofficial_category_id'},

// the 'area_name' in the script section should be the same name declared in the first parameter of the "addColumn()" API
