Question

我的应用程序有两个数据库连接：

mysql_default_connection => default_database
mysql_custom_connection => custom_database

我在使用Laravel unique验证方面遇到了一些问题。

protected $connection = 'mysql_custom_connection';

protected $table = 'aluno';

public $rules = [
    'email' => 'required|email|unique:custom_database.aluno'
];

当我尝试保存新模型时，唯一的规则可以正常运行，但是当从aluno中检索某些模型并尝试将其保存为：

$aluno = Aluno::find(1);
$aluno->attribute = 'new value';
$aluno->save();

此日志：

SQLSTATE[42S02]: Base table or view not found: 1146 Table 'default_database.aluno' doesn't exist (SQL: select count(*) as aggregate from `aluno` where `email` = aluno3@email.com and `id` <> 50)

如果我从验证中删除unique规则，请正常工作。

特别是，我无法理解为什么要查询Table 'default_database.aluno'，因为此数据库不是上面的模型连接。

有人可以向我解释为什么会这样吗？

我的连接配置

'connections' => [

    'mysql_default_connection' => [
        'driver'    => 'mysql',
        'host'      => 'localhost',
        'port'      => 3306,
        'database'  => 'default_database',
        'username'  => 'root',
        'password'  => '',
        'charset'   => 'utf8',
        'collation' => 'utf8_unicode_ci',
        'prefix'    => '',
    ],

    'mysql_custom_connection' => [
        'driver'    => 'mysql',
        'host'      => 'localhost',
        'port'      => 3306,
        'database'  => 'custom_database',
        'username'  => 'root',
        'password'  => '',
        'charset'   => 'utf8',
        'collation' => 'utf8_unicode_ci',
        'prefix'    => '',
    ],
];
'default' => 'mysql_default_connection',

aluno模型的相关部分

protected $connection = 'mysql_custom_connection';
protected $table = 'aluno';
public $rules = [
    'nome' => 'required|between:5, 45',
    'email' => 'required|email|unique:custom_database.aluno|max:64'
];

此规则适用于创建新模型

解

我正在使用实施Laravel的OctoberCMS，这个问题是OctoberCMS的麻烦而不是Laravel，对不起。要对模型进行验证，我们需要使用10月验证特性，使$rules, $attributeNames and $customMessages数组调用Validator::make()...。

在这个特性中，10月只是忽略验证时的模型连接

    /**
 * Instantiates the validator used by the validation process, depending if the class is being used inside or
 * outside of Laravel.
 * @return \Illuminate\Validation\Validator
 */
protected static function makeValidator($data, $rules, $customMessages, $attributeNames)
{
    return Validator::make($data, $rules, $customMessages, $attributeNames);
}

并且

  /*
  * Hand over to the validator
  */
  $validator = self::makeValidator($data, $rules, $customMessages, $attributeNames);

所以，我确实需要改变

 protected static function makeValidator($data, $rules, $customMessages, $attributeNames,$connection = null)
 {
     $validator = Validator::make($data, $rules, $customMessages, $attributeNames);
     if($connection !== null) {
         $validator->getPresenceVerifier()->setConnection($connection);
     }
     return $validator;
 }

并且

 $validator = self::makeValidator($data, $rules, $customMessages, $attributeNames,$this->connection);

现在就像一个魅力

$rules = [
  'email' => 'required|unique:aluno'
];

Answer 1

从验证中删除default_database，试试这个

public $rules = [
    'email' => 'required|email|unique:aluno'
];

如果要指定自定义连接

，请尝试此操作

public $rules = [
    'email' => 'required|email|unique:mysql_custom_connection.aluno'
];

Answer 2

试试这个

     $rules = [
          'email' => 'unique:mysql_custom_connection.aluno,email'
     ];

它有效，我现在已经尝试过了。只要了解aluno是表，就需要检查唯一的FIELD not table。
