Question

我实际上有一个让我发疯的问题。我是laravel的一个菜鸟，我上周做了一个tuto，并尝试用真正的项目学习。

我的用户和项目之间有一对多关系（一个用户可以创建多个项目）

这是我的2个型号：

class Project extends Eloquent {

    protected $table = 'projects';
    protected $fillable = array('name', 'description');
    public  $timestamps = true; 

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

我的用户模型：

class User extends Eloquent implements UserInterface, RemindableInterface {

    use UserTrait, RemindableTrait;

    protected $table = 'users';
    public  $timestamps = true;  
    protected $hidden = array('password', 'remember_token');

    public function tasks()
    {
        return $this->belongsToMany('Task');
    }

    public function projects()
    {
        return $this->hasMany('Project', 'created_by');
    }

}

然后，当我试图让我的项目显示它们时，用户的数据链接到它，它给了我一些奇怪的东西。这是我的方法：

    public function lists()
    {
        $projects = Project::all();//with('user')->get();
        return compact('projects');
    }

当我这样做时，而不是使用＆＃39;＆＃39;要进行连接（使用var_dump）

object(Illuminate\Database\Eloquent\Collection)[316]
  protected 'items' => 
    array (size=1)
      0 => 
        object(Project)[314]
          protected 'table' => string 'projects' (length=8)
          public 'timestamps' => boolean true
          protected 'connection' => null
          protected 'primaryKey' => string 'id' (length=2)
          protected 'perPage' => int 15
          public 'incrementing' => boolean true
          protected 'attributes' => 
            array (size=10)
              ...
          protected 'original' => 
            array (size=10)
              ...
          protected 'relations' => 
            array (size=0)
              ...
          protected 'hidden' => 
            array (size=0)
              ...
          protected 'visible' => 
            array (size=0)
              ...
          protected 'appends' => 
            array (size=0)
              ...
          protected 'fillable' => 
            array (size=0)
              ...
          protected 'guarded' => 
            array (size=1)
              ...
          protected 'dates' => 
            array (size=0)
              ...
          protected 'touches' => 
            array (size=0)
              ...
          protected 'observables' => 
            array (size=0)
              ...
          protected 'with' => 
            array (size=0)
              ...
          protected 'morphClass' => null
          public 'exists' => boolean true

我从tuto那里得到了我的例子，但是我做得非常激动，并且它不起作用。我希望得到类似的东西：

object(Post)[407]
  protected 'fillable' => 
    array (size=3)
      0 => string 'titre' (length=5)
      1 => string 'contenu' (length=7)
      2 => string 'user_id' (length=7)
  public 'timestamps' => boolean true
  protected 'connection' => null
  protected 'table' => null
  protected 'primaryKey' => string 'id' (length=2)
  protected 'perPage' => int 15
  public 'incrementing' => boolean true
  protected 'attributes' => 
    array (size=6)
      'id' => int 100
      'created_at' => string '2014-12-02 16:22:54' (length=19)
      'updated_at' => string '2014-12-02 16:22:54' (length=19)

如果有人知道原因，我会祝福你！

您正在检索所有记录，这就是您拥有[0]的原因，它是项目的数组（集合）

尝试只转储一个项目

$projects = Project::all();
var_dump($projects->first());

雄辩并没有回报它所期望的
