Question

我试图从用户表中获取帖子的作者，两个表都被创建并且两者都有关系。我在我的控制器中有这个代码

public function viewPost($id)
    {   
        $mytime = Carbon\Carbon::now();
        $post = Post::find($id);
        $by = $post->user()->get();
        $user = Auth::user();
        $this->layout->content = View::make('interface.viewPost')
        ->with('posts', $post )
        ->with('users',$user)
        ->with('date',$mytime)
        ->with('by',$by);

    }

这是用户/帖子的模型

帖子模型： class Post扩展了Eloquent {

        protected $fillable = array('email', 'password','title','content');

        protected $table = 'posts';

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

和我的用户模型

use Illuminate\Auth\UserTrait;
use Illuminate\Auth\UserInterface;
use Illuminate\Auth\Reminders\RemindableTrait;
use Illuminate\Auth\Reminders\RemindableInterface;

class User extends Eloquent implements UserInterface, RemindableInterface {

    use UserTrait, RemindableTrait;

    /**
     * The database table used by the model.
     *
     * @var string
     */
    protected $table = 'users';


    protected $fillable = array('email','password','title','content');

    /**
     * The attributes excluded from the model's JSON form.
     *
     * @var array
     */
    protected $hidden = array('password', 'remember_token');


    public function getRememberToken() 
    {
        return $this->remember_token;
    }


    public function setRememberToken($value) 
    {
        $this->remember_token = $value;
    }


    public function getRememberTokenName() 
    {
        return 'remember_token';
    }

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

    public function comments()
    {
        return $this->hasMany('Comment');
    }
}

Answer 1

您必须指定要加载您获得的帖子的用户。尝试以下

public function viewPost($id)
{   
    $mytime = Carbon\Carbon::now();
    $post = Post::with('user')->find($id);
    $by = $post->user;
    ...

}

您甚至无需向视图发送$by，因为您可以从视图内部$post->user->username

在非对象上调用成员函数user（）
