在 Laravel 航海者相关 table 中搜索
Search in Laravel voyager related table
有 2 个 table 用于管理类别,一个用于家长,另一个用于子类别。当我想用这个关联字段进行搜索时,我做不到。并得到这个错误
Error description
- Hizmetler 型号(子类别):
class Hizmetler extends Model
{
protected $primaryKey = 'hizmet_id';
protected $table = 'hizmetler';
public $incrementing = false;
use SoftDeletes;
protected $dates = ['deleted_at'];
public function Hizmetler(){
return $this->belongsTo(Hizmetler::class,'hizmet_ust_kategori');
}
}
- UstKategori 模型(父类别):
class UstKategori extends Model
{
protected $primaryKey = 'id';
protected $table = 'ust_kategori';
public $incrementing = false;

public function UstKategori(){
return $this->hasOne(UstKategori::class);
}
}

你的关系不正确。根据您的情况,类别与其child之间的关系是一对多。
Parent 型号:
class UstKategori extends Model
{
public function childs(){
return $this->hasMany(Hizmetler::class, 'hizmet_ust_kategori');
}
}
Child 型号:
class Hizmetler extends Model
{
public function parent(){
return $this->belongsTo(UstKategori::class, 'hizmet_ust_kategori');
}
}
