Laravel：关系问题？

Question

I'm beginning to think why did Laravel implement relationships to their framework, they've never worked for me and their a huge stress to fix when they break. This is the 5th time my relationships are returning null, even when ensuring I've set them up properly?

class UserStats extends Authenticatable
{
    protected $table = 'habbo_user_stats';
    public $timestamps = false;
    protected $guarded = ['id'];

    public function user()
    {
        return $this->belongsTo(User::class, 'id');
    }
}

And

class User extends Authenticatable
{
    protected $table = 'habbo_users';
    public $timestamps = true;
    protected $guarded = ['id'];

    public function stats() {
        return $this->belongsTo(UserStats::class, 'user_id');
    }
}

although, when calling

{{ $user->stats->some_column }}

stats is returning null... $user isn't null.

I think you have to define the owner of the relationship too. Ie:

public function stats() {
   // $this->hasMany OR $this->hasOne, depending on your use case.
   return $this->hasMany(UserStats::class, 'user_id');

}

We need to know here, does the user have many userstats? or the userstats have many user records? what are you planning to do here?
