Symfony 4 - 為動態用戶角色加載裝置
[英]Symfony 4 - load fixtures for dynamic user roles
問題描述
目前我正在嘗試修改我的類並尋找保存用戶和角色之間動態關系的想法。
我想在加載裝置時創建關聯，並在需要創建具有關系的用戶時在控制器中具有這樣的功能，例如：
...
$user = new User();
$user->setName($_POST['name']);
$user->setPassword($_POST['password']);
...
$user->setRole('ROLE_USER');//Role for everyone
...
$role = new Role();
$role->setName('ROLE_' . strtoupper($_POST['name']) );//Role for personal use
...
//Here need to implement user+role association (I'm looking for recommendations)
...
$entityManager->persist($user);
$entityManager->persist($role);
//Persist role+user assosiacion
$entityManager->flush();
$entityManager->clear();

我正在尋找以下方面的建議：
用戶實體緩存在注解中，因為每個請求的 symfony 都會加載它。 配置部分：
orm: metadata_cache_driver: type: redis result_cache_driver: type: redis query_cache_driver: type: redis
我在 redis 中緩存所有數據 1 分鍾。 有什么更好的解決辦法嗎？
DB 模式在 users_roles 表上創建外鍵 (FK) 和額外的索引，我希望沒有 FK，因為恕我直言，這是“重”的事情。 我寧願只在 (user_id,role_id) 上使用主鍵。 這方面有什么建議嗎？

我會嘗試回答這個問題，但正如我在評論中提到的，這個問題有點大，所以其中一些可能是概括的。
- 用戶實體緩存在注解中，因為每個請求的 symfony 都會加載它。 配置部分：
orm: metadata_cache_driver: type: redis result_cache_driver: type: redis query_cache_driver: type: redis我在 redis 中緩存所有數據 1 分鍾。 有什么更好的解決辦法嗎？
當你在這里說“更好”時，這是主觀的。 每個應用程序都是不同的。 緩存以及緩存保持活動的長度特定於每個應用程序的要求。 我不知道這是否有任何本質上的錯誤，但這在很大程度上取決於您的應用程序的要求。
- DB 模式在 users_roles 表上創建外鍵 (FK) 和額外的索引，我希望沒有 FK，因為恕我直言，這是“重”的事情。 我寧願只在 (user_id,role_id) 上使用主鍵。 這方面有什么建議嗎？
首先，FK 很重要，它們旨在保持數據的完整性。 它們確保如果有人試圖刪除user_roles行鏈接到的用戶或角色，操作將失敗。 您通常希望這種行為不會丟失數據或創建孤立數據。
其次，我不確定您使用的是什么版本的 Doctrine，但我類似的 ManyToMany 表確實在(user_id, role_id)上創建了 PK 和唯一索引。
- user+role+roles_users靈活增刪解決方案
您可以通過使用 Doctrine 的ArrayCollections （單擊菜單中的 Collections 以確保錨鏈接有效，它們有時會損壞）來完成此操作。
但是，在使用默認的 Symfony User實體執行此操作時有一個警告。 它實現了Symfony\\Component\\Security\\Core\\User\\UserInterface接口，該接口定義了一個getRoles()方法，該方法旨在將角色數組作為字符串返回。 這是為了使某些 Symfony 安全功能按預期工作。 這意味着，如果您有一個private $roles屬性，您必須將其標准 Doctrine getter 重命名為其他名稱，以便您可以讓getRoles()按預期運行。
因此，對於User實體，我通常只是將我的 getter、setter、adder 和 remover 重命名為getUserRoles() 、 setUserRoles() 、 addUserRole()和removeUserRole() ，然后我離開getRoles()來實現預期的界面。
這是一個沒有 Role 類示例的用戶類的不完整示例。

}
/* ... */
}
如果您願意，您也可以對Role對象執行相反的操作，但這取決於您是否希望以這種方式將用戶添加到角色，並且通常最好選擇關系的擁有方。
下面是一個示例，說明如何在您使用實體、裝置或其他方式的任何地方使用它。
<?php
use Doctrine\Common\Collections\ArrayCollection;
use App\Entity\User;
use App\Entity\Role;
$entityManager = (get entity manager);
$user = new User();
// You can also add the name as an argument to Role::__construct()
// then call from setName() from that if you wanted to simplify this.
$roleFoo = (new Role())->setName('ROLE_FOO');
$roleBar = (new Role())->setName('ROLE_BAR');
// set roles using ArrayCollection of roles.
$user->setUserRoles(new ArrayCollection($roleFoo, $roleBar));
// add new role, see User::addUserRole() for
$user->addUserRole((new Role()->setName('ROLE_WIN'));
// remove ROLE_BAR
// You can also do this with entities that you find with Doctrine
// if you want to remove them from a persisted collection.
$user->removeUserRole($roleBar);
// get roles as a collection of Role objects.
// This will return either ArrayCollection or PersistentCollection
// depending on context. These are objects that act like arrays
// and each element will be a Role object.
$roles = $user->getUserRoles();
// get roles as strings... mostly used by Symfony's security system
// but could be used by your app too.
$roleStrings = $user->getRoles();
