Try this:
class User extends Model
{
protected $fillable = ['name','username','password'];
public function articles()
{
return $this->hasMany('App\ArticleUser')->with('article');
}
public function tags()
{
return $this->hasMany('App\Tag');
}
}
class ArticleUser extends Model
{
public funciton article()
{
return $this->belongsTo('App\Article');
}
public function user()
{
return $this->belongsTo('App\User');
}
public function tags()
{
return $this->belongsToMany('App\Tag');
}
}
class Article extends Model
{
protected $fillable = ['title','content'];
}
class Tag extends Model
{
protected $fillable = ['title','content'];
public function articles()
{
return $this->belongsToMany('App\ArticleUser')->with('article');
}
public function user()
{
return $this->belongsTo('App\User');
}
}
