Question

我已经为一个大学项目建立了一个基本的laravel社交媒体网站，虽然其中很多都在运作，但我对朋友表的不满存在问题。我可以让朋友循环显示，但由于某种原因，它只会反复显示用户个人资料页面名称，这取决于他们在数据库中的朋友数量，我已多次通过代码但是只是看不出原因。我的代码低于

我的代码在下面：

User.php

<?php

namespace App;

use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable
{
/**
 * The attributes that are mass assignable.
 *
 * @var array
 */

protected $table = 'users';

protected $fillable = [
    'id', 'username','firstName', 'lastName', 'bio', 'DoB', 'homeLocation', 'currentLocation', 'journeys', 'friends', 'email', 'password',
];

/**
 * The attributes excluded from the model's JSON form.
 *
 * @var array
 */

protected $hidden = [
    'password', 'remember_token',
];


public function getName()
{
    if ($this->firstName && $this->lastName) {
        return "{$this->firstName} {$this->lastName}";
    }

    if ($this->firstName) {
        return $this->firstName;
    }

    return null;
}

public function getNameOrUsername()
{
    return $this->getName() ?: $this->username;
}

public function getFirstNameOrUsername()
{
    return $this->firstName ?: $this->username;
}

public function getAvatarUrl()
{
    return "https://www.gravatar.com/avatar/{{ md5($this->email) }}?d=mm";
}

public function statuses()
{
    return $this->hasMany('App\Posts', 'user_id');
}

public function friendsOfMine()
{
    return $this->belongsToMany('App\User', 'friends', 'user_id', 'friend_id');
}

public function friendsOf()
{
    return $this->belongsToMany('App\User', 'friends', 'friend_id', 'user_id');
}

public function friends()
{
    return $this->friendsOfMine()->wherePivot('accepted', true)->get()->merge($this->friendsOf()->wherePivot('accepted', true)->get());
}

public function friendRequests()
{
    return $this->friendsOfMine()->wherePivot('accepted', false)->get();
}

public function friendRequestsPending()
{
    return $this->friendsOf()->wherePivot('accepted', false)->get();
}

public function hasFriendRequestPending(User $users)
{
    return (bool) $this->friendRequestsPending()->where('id', $users->id)->count();
}

public function hasFriendRequestReceived(User $users)
{
    return (bool) $this->friendRequests()->where('id', $users->id)->count();
}

public function addFriend(User $users)
{
    $this->friendsOf()->attach($users->id);
}

{
    $this->friendRequests()->where('id', $users->id)->first()->pivot->update([
        'accepted' => true,
