我已经建立了多对多的联系。下面的代码解释了我所做的事情。我已经在一个多选组合框中检索到了干预区域,现在我正在尝试将它们插入到数据库中。当我尝试选择多个区域时,会显示错误消息(在标题中)。如果有人能帮我,我将不胜感激。
模式1
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class technicien extends Model
{
public function zoneintervention()
{
return $this->belongsToMany('App\zoneintervention','technicien_zone','technicien_id','z
oneintervention_id');
}
public function tarificationtache()
{
return $this->hasMany(Tarificationtache::class);
}
}
型号2

use Illuminate\Database\Eloquent\Model;
class zoneintervention extends Model
{
public function techniciens()
{
return $this->belongsToMany('App\technicien','technicien_zone','zoneintervention_id','technicien_id');
