我正在使用 laravel 背包来建立后台管理，我坚持这一点，这可能是一个非常基本的疑问。
我的情况是：
表事件：
id - name - themeID - 更多字段...
表主题：
身份证 - 姓名
所以，一个主题可以有各种事件，一个事件可以有各种主题，我对如何实现这一点有一些疑问，我做了什么：
主题.php
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
use Backpack\CRUD\CrudTrait;
class Theme extends Model
{
use CrudTrait;
/*
|--------------------------------------------------------------------------
| GLOBAL VARIABLES
|--------------------------------------------------------------------------
*/
protected $table = 'themes';
//protected $primaryKey = 'id';
// public $timestamps = false;
// protected $guarded = ['id'];
protected $fillable = ['name'];
// protected $hidden = [];
// protected $dates = [];
/*
|--------------------------------------------------------------------------
| FUNCTIONS
|--------------------------------------------------------------------------
*/
/*
|--------------------------------------------------------------------------
| RELATIONS
|--------------------------------------------------------------------------
*/
public function Theme() {
return $this->hasMany('App\Models\Event');
}
/*
|--------------------------------------------------------------------------
| SCOPES
|--------------------------------------------------------------------------
*/
/*

/*

protected $table = 'events';
//protected $primaryKey = 'id';

// protected $guarded = ['id'];
protected $fillable = ['name','theme','schedules','themeID','countyID','event_typeID','offered_conditionID','alone_with_typeID','tagID',

我需要数据透视表吗？我错过了什么？我发现这方面的文档很少。
我得到的错误如下：
数组到字符串的转换，他尝试保存字段 array('1','2') 并且错误发生在那里。
