Laravel 4 检查唯一性 /数据库/ 忽略当前

当然，有必要阅读更多文件， laravel 4 可以...

我有

$rules = array/'username' => 'required|unique:users'/;

我有的

$rules = array/'username' => 'required|unique:users,username,'.$id/;

你可以告诉验证器忽略这个 ID, 如上所述。

这个决定为我工作：

protected $rules = array/

 'email' => "required|email|unique:users,email,:id",

/;

为了 Laravel 4.1, 如果延长课程

Illuminate\Validation\Validator

, 覆盖方法

validateUnique//

因此：

/**

 * Validate the uniqueness of an attribute value on a given database table.

 *

 * If a database column is not specified, the attribute will be used.

 *

 * @param string $attribute

 * @param mixed $value

 * @param array $parameters

 * @return bool

 */

protected function validateUnique/$attribute, $value, $parameters/

{

 $this->requireParameterCount/1, $parameters, 'unique'/;



 $table = $parameters[0];



 // The second parameter position holds the name of the column that needs to

 // be verified as unique. If this parameter isn't specified we will just

 // assume that this column to be verified shares the attribute's name.

 $column = isset/$parameters[1]/ ? $parameters[1] : $attribute;



 // If the specified ID column is present in the data, use those values; otherwise,

 // fall back on supplied parameters.

 list/$idColumn, $id/ = [null, null];

 if /isset/$parameters[2]// {

 list/$idColumn, $id/ = $this->getUniqueIds/$parameters/;



 if /strtolower/$id/ == 'null'/ $id = null;

 else if /strtolower/$id/ == 'id' && isset/$this->data[$idColumn]// $id = $this->data[$idColumn];

 }

 else if /isset/$this->data['id']// {

 $idColumn = 'id';

 $id = $this->data[$idColumn];

 }



 // The presence verifier is responsible for counting rows within this store

 // mechanism which might be a relational database or any other permanent

 // data store like Redis, etc. We will use it to determine uniqueness.

 $verifier = $this->getPresenceVerifier//;



 $extra = $this->getUniqueExtra/$parameters/;



 return $verifier->getCount/



 $table, $column, $value, $id, $idColumn, $extra



 / == 0;

}

在您的验证器规则中，您可以执行此操作 /检查领域的存在

id

在数据验证中 - 这是最广泛的用途。/:

$rules = 'unique:model,field';

这是 /检查领域的存在

id

在数据检查中/ /相当于上面的/:

// specifying anything other than 'id' or 'null' as the 3rd parameter

// will still use the current behavior

$rules = 'unique:model,field,id';

或者那个 /检查领域的存在

idColumn

在数据检查中/:

// specifying anything other than 'id' or 'null' as the 3rd parameter

// will still use the current behavior

$rules = 'unique:model,field,id,idColumn';

嗨，您可以使用验证程序作为服务或复制逻辑并应用您需要的内容

$valitator = MyCustomValidator::make//->on/'update'/->setCurrent/$id/;
