Php Laravel仅删除相关模型，但不删除主模型

我有一个简单的查询，运行方式如下：

$reviews = Review::whereHas('units', function ($q) use ($after_start_unit_ids) {
        $q->whereIn('units.id', $after_start_unit_ids);
    })
    ->withCount('units')
    ->with(['units' => function($q) use($after_start_unit_ids) {
        $q->whereIn('id', $after_start_unit_ids);
    }])
    ->where('action',1)
    ->where('amenity_value_id', $request->av_id)
    ->where('property_id', $property_id)
    ->where('status', 1)
    ->get();


foreach($reviews as $tk => $tv){
    if($tv->units_count == $tv->units->count()){
//      DB::connection()->enableQueryLog();
        Review::where('id', $tv->id)->forceDelete();
//      $queries = DB::getQueryLog();
//      pe($queries);
    } else {
        $tv->units()->detach($after_start_unit_ids);
    }
}

这里，行

Review:：where（'id'，$tv->id）->forceDelete（）不工作。令人惊讶的是，它不会产生任何错误。但是，它确实会从透视表
review\u unit
中删除相关数据，但不会从主
reviews
表中删除

我已启用查询日志，它尝试运行的查询为：

array:1 [
  0 => array:3 [
    "query" => "delete from `reviews` where `id` = ?"
    "bindings" => array:1 [
      0 => 287
    ]
    "time" => 0.53
  ]
]

因此，我尝试从

reviews

where

id

=287

复制这个查询

delete，并直接从phpmyadmin运行它。从PHPmyadmin运行良好。我在这里迷路了，我甚至不知道发生了什么

此表模型如下所示：

<?php

namespace App\Models;

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

class Review extends Model
{
    use SoftDeletes;
    protected $table = 'reviews';

    protected $guarded = ['id'];
    protected $dates = ['created_at','updated_at'];

    /**===========
     * Relations
    =============*/

    /**
     * @return \Illuminate\Database\Eloquent\Relations\BelongsTo
     */
    public function property()
    {
        return $this->belongsTo('App\Models\Property');
    }

    /**
     * Return respected amenity
     * @return \Illuminate\Database\Eloquent\Relations\BelongsTo
     */
    public function amenityValue()
    {
        return $this->belongsTo('App\Models\AmenityValue');
    }

    public function unitAmenityValues()
    {
        return $this->hasMany(
            'App\Models\UnitAmenityValue',
            'amenity_value_id',
            'amenity_value_id'
        );
    }

    Public function units()
    {
        return $this->belongsToMany('App\Models\Unit', 'review_unit');
    }

    public function amenity()
    {
        return $this->belongsTo('App\Models\Amenity');
    }
    public function category()
    {
        return $this->belongsTo('App\Models\Category');
    }
}
