Question

我有以下表用户表，帖子表和配置文件表。帖子属于用户，个人资料属于用户。我也有一个论坛，人们可以发帖我希望用户的用户名显示而不是他们的名字。但是用户名在个人资料表中，我不知道如何获取它。

这是我的代码

    class Post extends Model
{
    //
     public function users(){
        return $this->belongsToMany('App\User','posted_by');
    }

    class Profile extends Model
{
    //
      public function users(){

        return $this->belongsTo('App\User','whos_profile');


    }


class User extends Authenticatable
{
    use Notifiable;

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'firstname','lastname', 'email', 'password',
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];
   public function profile(){
      return $this->hasOne('App\Profile');
    }

    public function post(){
      return $this->hasMany('App\Post');
    }

}`enter code here`

Answer 1

您可以按照以下方式获取

$user = User::find($id);
if($user->profile){
   echo $user->profile->username;
}

Answer 2

你应该试试这个：

$rsltUsers = User::with(['profile','post'])->where('id',$id)->get();

foreach($rsltUsers as $rsltUsers){

  dd($user->profile->username);

}

Laravel从其他表中获取信息
