【问题描述】：
我们知道 laravel 有一个 update() 方法，通过“put”http 方法更新记录。一切都很正常，除非我尝试针对我的用户模型中的静态 $rules 方法验证新输入值。 请看看我的模型
protected $guarded = ['id', 'admin'];
public static $rules = [
'name' => 'required|min:4',
'username' => 'required|min:3|alpha_num|unique:users',
'email' => 'required|email|unique:users',
'password' => 'required|alpha_num|between:5,12|confirmed',
'password_confirmation' => 'required|alpha_num|between:5,12',
'phone' => 'required|min:5|alpha_num',
'city' => 'required|min:2|alpha',
'town' => 'required|min:2|alpha_num',
'address' => 'required|min:5|alpha_num',
'blood' => 'required|min:2',
'img' => 'image|mimes:jpeg,jpg,bmp,png,gif',
'active' => 'integer',
'admin' => 'integer'
];
您看到我已将电子邮件设置为 user 表的唯一性。因此，当我尝试更新有关登录用户个人资料信息的记录时，如果我更新所有记录以及电子邮件地址，它就可以工作。但是，如果我将电子邮件字段保持原样，则会引发验证错误，说明电子邮件地址已被占用。 但我希望 laravel 只验证更新的字段，以便用户可以更新他们想要的任何内容，或者像以前一样保留一两个。 有没有办法做到这一点？
现在请检查负责更新新输入数据的控制器方法
//update the changes now
public function update($id) {
$user = User::find($id);
$validator = Validator::make(Input::all(), User::$rules);
$input = array_except(Input::all(), ['_method', 'password_confirmation']);
if( $validator->passes() ) {
$user->save($input);
return Redirect::to('donors/'.$user->username.'/profile')
->withMessage('Information Updated');
}
return Redirect::to('donors/'.$user->username.'/profile/edit')
->withMessage('Something went wrong! Please fix the errors.')
->withErrors($validator)
->withInput();
}
为了更清楚地理解场景，我也添加了视图表单和路由文件sn-p。
路线
Route::put('donors/{id}', ['uses'=>'DonorsController@update']);
查看表单
{{ Form::open(['url'=>'donors/'.$donor->id, 'method'=>'put', 'role'=>'form']) }}
<table class="table table-bordered donors-table">
<colgroup>
<col class="col-xs-1">
<col class="col-xs-7">

<tr class="odd">

<tr class="odd">

<span class="text-green">City</span>

<td>
{{ Form::text('city', $donor->city) }}
<span class="text-red input-error">{{ $errors->first('city') }}</span>

<td>
{{ Form::text('phone', $donor->phone) }}
<span class="text-red input-error">{{ $errors->first('phone') }}</span>
</td>
</tr>
<tr>
</tbody>
</table>
<p class="submit clearfix">
{{ Form::submit('Update', ['class'=>'btn btn-success pull-left']) }}
{{ link_to('donors/'.$donor->username.'/profile', 'Cancel', ['class'=>'pull-right btn btn-danger']) }}
</p>
{{ Form::close() }}
请问我有什么遗漏吗？ 让我知道是否应该显示我的代码的任何其他 sn-p。
