Laravel 唯一且存在验证 - Class 不存在
Laravel Unique and Exists Validation - Class Does Not Exist
好的，我使用 lumen 5.4，我对某些事情有点困惑，我一直使用这两个验证，如下所示：
$rules = [
"field1" => "required|exists:users",
"field2" => "required|unique:users"
];
$messages = [
"field1.exists" => "Lorem ipsum dolor sit amet.",
"field2.unique" => "Lorem ipsum dolor sit amet."
];
$validator = Validator::make($request->all(), $rules, $messages);
if ($validator->fails()) {
return response($validator->errors(), 400);
}
就像文档所说的那样，其中 "users" 是数据库中 table 的名称。但是现在突然间我得到
Error 500 Class users does not exist
这让我很困惑，再次检查了文档，它说要使用 table 名称，所以我只是假设有一些更新，它现在使用模型名称，所以我尝试了。
问题是我的所有模型都在具有以下命名空间的模型文件夹中：App\Models;
然后我尝试了：
$rules = [
‘field1’ => "required|exists:User",
‘field2’ => "required|unique:User"
];
和
$rules = [
‘field1’ => "required|exists:\App\Models\User",
‘field2’ => "required|unique:\App\Models\User"
];
和
$rules = [
‘field1’ => "required|exists:App/Models/User",
‘field2’ => "required|unique:App/Models/User"
];
和
$rules = [
‘field1’ => "required|exists:App\Models\User",
‘field2’ => "required|unique:App\Models\User"
];
None 其中有效，我已经在 Java 中编码了一段时间，所以我可能忘记了我的东西，我在这里做错了。

老实说，我什至不熟悉 laravel 原则，我只是一直遵循 laravel/lumen 文档，这就是我一直用来构建我的应用程序的方法。
我假设您正在使用 laravel-doctrine 包（来自该堆栈跟踪）。 documentation 表示要进行 unique 验证，您应该使用 2 个参数：
/**
* Store a new blog post.
*
* @param Request $request
* @return Response
*/
public function store(Request $request)
{
$this->validate($request, [
'username' => 'required|unique:App\User,username',
]);
}
exists 验证：
/**
* Store a new blog post.
*
* @param Request $request
* @return Response
*/
public function update($id, Request $request)
{
$this->validate($request, [
'username' => 'required|exists:App\User,username',
]);
}
所以在你的情况下，它将是：
$rules = [
"field1" => "required|exists:App\User,field1",
"field2" => "required|unique:App\User,field2"
];
$messages = [
"field1.exists" => "Lorem ipsum dolor sit amet.",
"field2.unique" => "Lorem ipsum dolor sit amet."
];
$validator = Validator::make($request->all(), $rules, $messages);
if ($validator->fails()) {
return response($validator->errors(), 400);
}
更新
如果你得到错误：Call to a member function createQueryBuilder() on null，那么你忘记装饰你的 Doctrine Metadata。在您的情况下，您需要更新 App\Models\User class:
use Doctrine\ORM\Mapping AS ORM;
/**
* @ORM\Entity
* @ORM\Table(name="users")
*/
class User
{
/**
* @ORM\Id
* @ORM\GeneratedValue
* @ORM\Column(type="integer")
*/
public $id;
/**
* @ORM\Column(type="string")
*/
public $field1;
/**
* @ORM\Column(type="string")
*/
public $field2;
}
好的，我使用 lumen 5.4，我对某些事情有点困惑，我一直使用这两个验证，如下所示：
$rules = [
"field1" => "required|exists:users",
"field2" => "required|unique:users"
];
$messages = [
"field1.exists" => "Lorem ipsum dolor sit amet.",
"field2.unique" => "Lorem ipsum dolor sit amet."
];
$validator = Validator::make($request->all(), $rules, $messages);
if ($validator->fails()) {
return response($validator->errors(), 400);
}
就像文档所说的那样，其中 "users" 是数据库中 table 的名称。但是现在突然间我得到
Error 500 Class users does not exist
这让我很困惑，再次检查了文档，它说要使用 table 名称，所以我只是假设有一些更新，它现在使用模型名称，所以我尝试了。
问题是我的所有模型都在具有以下命名空间的模型文件夹中：App\Models;

‘field2’ => "required|unique:\App\Models\User"
];
和
$rules = [
‘field1’ => "required|exists:App/Models/User",
‘field2’ => "required|unique:App/Models/User"
];
和
$rules = [
‘field1’ => "required|exists:App\Models\User",
‘field2’ => "required|unique:App\Models\User"
];

更改我的验证规则以使用我的模型而不是 table 名称后，我现在收到此错误：

老实说，我什至不熟悉 laravel 原则，我只是一直遵循 laravel/lumen 文档，这就是我一直用来构建我的应用程序的方法。
我假设您正在使用 laravel-doctrine 包（来自该堆栈跟踪）。 documentation 表示要进行 unique 验证，您应该使用 2 个参数：
/**
* Store a new blog post.
*
* @param Request $request
* @return Response
*/
public function store(Request $request)
{
$this->validate($request, [
'username' => 'required|unique:App\User,username',
]);
}
exists 验证：
/**
* Store a new blog post.
*
* @param Request $request
* @return Response
*/
public function update($id, Request $request)
{
$this->validate($request, [
'username' => 'required|exists:App\User,username',
]);
}
所以在你的情况下，它将是：
$rules = [
"field1" => "required|exists:App\User,field1",
"field2" => "required|unique:App\User,field2"
];
$messages = [
"field1.exists" => "Lorem ipsum dolor sit amet.",
"field2.unique" => "Lorem ipsum dolor sit amet."
];
$validator = Validator::make($request->all(), $rules, $messages);
if ($validator->fails()) {
return response($validator->errors(), 400);
}
更新
如果你得到错误：Call to a member function createQueryBuilder() on null，那么你忘记装饰你的 Doctrine Metadata。在您的情况下，您需要更新 App\Models\User class:
use Doctrine\ORM\Mapping AS ORM;
/**
* @ORM\Entity
* @ORM\Table(name="users")
*/
class User
{
/**
* @ORM\Id
* @ORM\GeneratedValue
* @ORM\Column(type="integer")
*/
public $id;
/**
* @ORM\Column(type="string")
*/
public $field1;
/**
* @ORM\Column(type="string")
*/
public $field2;
}
