Laravel Eloquent delete() 不起作用

Laravel Eloquent的delete()方法在某些情况下可能会出现无法正常工作的问题。在本文中，我们将深入探讨这个问题，并为您提供解决方案。我们还将通过一个案例代码来说明问题的具体细节。

php
public function deleteRecord($id)
{
    $record = Record::find($id);
    
    if (Gate::allows('delete', $record)) {
        $record->delete();
        return redirect()->back()->with('success', 'Record deleted successfully.');
    } else {
        return redirect()->back()->with('error', 'You do not have permission to delete this record.');
    }
}

php
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;
class Article extends Model
{
    use SoftDeletes;
    
    protected $dates = ['deleted_at'];
    
    public function comments()
    {
        return $this->hasMany('App\Comment');
    }
}

php
use Illuminate\Database\Eloquent\Model;
class Comment extends Model
{
    public function article()
    {
        return $this->belongsTo('App\Article');
    }
}

php
public function deleteArticle($id)
{
    $article = Article::find($id);
    
    // 解除关联约束
    $article->comments()->delete();
    
    // 执行删除操作
    $article->delete();
    
    return redirect()->back()->with('success', 'Article deleted successfully.');
}
