我正在使用Laravel 4和MongoDB實現身份驗證，並使用https://github.com/jenssegers/Laravel-MongoDB作爲後端。Laravel 4與MongoDB的關係
我的用戶模型是這樣的：
use Illuminate\Auth\UserInterface;
/**
* Class User
* @property string $username
* @property string $password
*/
class User extends Moloquent implements UserInterface {
/**
* Primary key for collection
*
* @var string
*/
protected $primaryKey = 'username';
/**
* The attributes excluded from the model's JSON form.
*
* @var array
*/
protected $hidden = array('password');
/**
* Relationship with role
*
* @return \Illuminate\Database\Eloquent\Relations\HasOne
*/
public function role() {
return $this->belongsTo('Role');
}
/**
* Get the unique identifier for the user.
*
* @return mixed
*/
public function getAuthIdentifier()
{
return $this->username;
}
/**
* Get the password for the user.
*
* @return string
*/
public function getAuthPassword()
{
return $this->password;
}
/**
* Get the token value for the "remember me" session.
*
* @return string
*/
public function getRememberToken()
{
return $this->remember_token;
}
/**
* Set the token value for the "remember me" session.
*
* @param string $value
* @return void
*/
public function setRememberToken($value)
{
$this->remember_token = $value;
}
/**
* Get the column name for the "remember me" token.
*
* @return string
*/
public function getRememberTokenName()
{
return 'remember_token';
}
}
，這是我的榜樣：
/**
* Class Role
* @property string name
*/
class Role extends Moloquent {
/**
* Primary key for collection
*
* @var string
*/
protected $primaryKey = 'name';
/**
* Collection name for role
*
* @var string
*/
protected $collection = 'roles';
/**
* Relationship with users
*
* @return \Illuminate\Database\Eloquent\Relations\BelongsToMany
*/
public function users() {
return $this->belongsToMany('User');
}
}
正如你看到的，我的用戶只能username和password和角色只有name。
問題是，如何保存相關模型？我嘗試了很多方法，如在Laravel Eloqoent文檔中，如$user->role()->save($role)或attach而不是save，但只有$role->users()->save($user)正常工作。爲什麼？它們不應該全部工作嗎？我似乎不瞭解Laravel的關係概念非常好。
另一件事是如何獲得用戶的角色？例如：
$user = Auth::user();
var_dump($user->role()->get());
給出一個空的集合。這不應該給我用戶的角色？
我很困惑！
預先感謝您。
編輯：這裏是我的接種：將
class RoleTableSeeder extends Seeder {
public function run() {
$adminRole = Role::where('name', 'admin')->first();
if(empty($adminRole)) {
Role::create(array(
'name' => 'admin',
));
Role::create(array(
'name' => 'superuser',
));
Role::create(array(
'name' => 'user',
));
}
}
}
class UserTableSeeder extends Seeder {
public function run() {
$admin = User::where('name', 'admin')->first();
if(empty($admin)) {
$role = Role::where('name', 'admin')->first();
$admin = new User();
$admin->username = 'admin';
$admin->password = Hash::make('[email protected]%%');
$admin->save();
$role->users()->attach($admin);
}
}
}
