我刚做了一个账户删除功能，但我遇到了一个问题。我还需要删除用户的帖子，在删除帐户。我怎样才能做到？我有表用户，其中我有来自用户的所有详细信息，还有表帖子，其中还有帖子的用户id和id，标题和图像。

公共函数删除（$id）

public function delete($id)
    {
        $profile = User::find($id);


        $profile->delete();
        Session::flash('remove', "The profile was successfully deleted!");
        return redirect('login');
    }

Profile.php

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Profile extends Model
{

    protected $guarded = [];

    public function profileImage(){

        $imagePath = ($this->image) ?  $this->image : 'profile/vx2k9TEhkcgaRdOWKvs4lsxqOVmuzwumtwySEnvH.png';
        return '' . $imagePath;
    }

    public function user(){

        return $this->belongsTo(User::class);
    }

    public function followers(){
        return $this->belongsToMany(User::class);

    }


}

使用者php

<?php
namespace App;


use App\Mail\NewUserWelcomeMail;
use Illuminate\Notifications\Notifiable;
use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Support\Facades\Mail;
use Actuallymab\LaravelComment\CanComment;


class User extends Authenticatable
{
    use Notifiable;
    /**
     * The attributes that are mass assignable.
     *

     */
    protected $fillable = [
        'name', 'email', 'username', 'password',
    ];
    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];
    /**
     * The attributes that should be cast to native types.
     *
     * @var array
     */
    protected $casts = [
        'email_verified_at' => 'datetime',
    ];
    protected static function boot()
    {
        parent::boot();

        static::created(function ($user) {
            $user->profile()->create([
                'title' => $user->username,
            ]);

        });
    }
    public function posts()
    {
        return $this->hasMany(Post::class)->orderBy('created_at', 'DESC');
    }



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