Laravel 验证唯一

Question

我有一个带有唯一列的 table。我的表单验证规则如下所示：

    return Validator::make($data, [
      'nameEN'   => 'required|string',
      'nameHE'   => 'required|string',
      'address'  => 'required|string|min:10|unique:clients'
    ]);

我的问题是，当我编辑一行时，如果我没有更改地址列，则会收到验证错误。

我的编辑功能是这样的：

public function editPost(Request $request,$id){
    $client = new Client();
    $client->editValidation($request->all())->validate();
    $row = $client->where('id',$id)->get()->first();
    $update = array();
    if(!empty($request->input("nameEN"))    && $request->input("nameEN")    != $row->nameEN) $update["nameEN"] = $request->input("nameEN");
    if(!empty($request->input("nameHE"))    && $request->input("nameHE")    != $row->nameHE) $update["nameHE"] = $request->input("nameHE");
    if(!empty($request->input("address"))   && $request->input("address")   != $row->address) $update["address"] = $request->input("address");

    if(empty($update)) $message = $this->message("info", "Notic: Client {$row->nameEN} was not updated because nothing was changed.");
    else if($client->where("id",$row->id)->update($update)){
        $message = $this->message("success", "Client {$row->nameEN} was updated.");
    } else {
        $message = $this->message("danger", "Error: Client {$row->nameEN} was not updated.");
    }
    $redirect = redirect("clients");
    if(isset($message)) $redirect->with("message",$message);
    return $redirect;
}

如果我从我的验证规则中删除 unique，我可能会遇到 mysql 错误。

如何解决这个问题？

提前致谢。

Answer 1

来自docs：

有时，您可能希望在唯一性检查期间忽略给定的 ID，指示验证器忽略对象的 ID

'address'  => 'required|string|min:10|unique:clients,address,'.$id

或者您可以使用 Rule class

use Illuminate\Validation\Rule;

Validator::make($data, [
   'address' => [
        Rule::unique('clients')->ignore($id),
  ]
]);

If your table uses a primary key column name other than id, you may specify the name of the column when calling the ignore method:

'address' => Rule::unique('clients')->ignore($id, 'primary_key')

用于验证 laravel 5.6 上的唯一列：

仅用于按需使用的字段：

唯一：table，列，除了，idColumn

'address'  => 'required|string|min:10|unique:clients,address,'.$id

当您想使用单独的 class 进行验证时。我使用一个通用的 class 作为添加和更新：

public function rules()
{
  if($this->method() == 'POST')
      $address = 'required|string|min:10|unique:clients,address';
  else
     $address  = 'required|string|min:10|unique:clients,address,'.$this->id;
   //put a hidden input field named id with value on your edit view and catch it here; 
    return [
       'nameEN'   => 'required|string',
       'nameHE'   => 'required|string',
       'address'  => $address
    ];
}
