在Laravel中制作Ardent，不需要保存新密码

问题描述：

I'm doing user editing facility for my admin panel. I want to ignore empty password on update, but not on create.

I have following validation rules for User model:

public static $rules = array(
    'login'                 => 'required|max:255|alpha_dash|unique',
    'displayname'           => 'required|max:255|unique',
    'email'                 => 'required|email|max:255|unique',
    'password'              => 'required|confirmed',
    'password_confirmation' => 'required',
);

But it doesn't let me update user model when I don't pass password to it. It just complains about not having a password.

How to make it work?

我正在为我的管理面板进行用户编辑工具。我想在更新时忽略空密码，但不想在创建时忽略。 p>

我有以下用户模型的验证规则： p>

  public static  $ rules = array（
'login'=＆gt;'required | max：255 | alpha_dash | unique'，
'displayname'=＆gt;'required | max：255 | unique'，
'email'=＆gt  ;'required | email | max：255 | unique'，
'password'=＆gt;'required | confirmed'，
'passate_confirmation'=＆gt;'required'，
）; 
  code>  
 
 但是当我不向其传递密码时，它不允许我更新用户模型。 它只是抱怨没有密码。 p> 
 
 
如何使它工作？ p> 
  div>

You can do something like this in your controller:

if ($user->exists)
{
    $user::$rules['password'] = (Input::get('password')) ? 'required|confirmed' : '';
    $user::$rules['password_confirmation'] = (Input::get('password')) ? 'required' : '';
}

$user->save();

That's something people are still thinking about. But usually create rules and update rules will be different.

public static $create_rules = array(
    'login'                 => 'required|max:255|alpha_dash|unique',
    'displayname'           => 'required|max:255|unique',
    'email'                 => 'required|email|max:255|unique',
    'password'              => 'required|confirmed',
    'password_confirmation' => 'required',
);

public static $update_rules = array(
    'login'                 => 'required|max:255|alpha_dash|unique',
    'displayname'           => 'required|max:255|unique',
    'email'                 => 'required|email|max:255|unique',
);

Then in your validation code, you can

if ( ! $this->exists || Input::get('password'))
{
   $validation_rules = static::$create_rules;
}
else
{
   $validation_rules = static::$update_rules;
}

If you want to consolidate this behavior to the model itself (so it doesn't matter where it's being created/saved from) you can utilize Ardent's beforeValidate function to change the rules before validating:

public function beforeValidate() { if(isset($this->id)) { self::$rules['password'] = 'confirmed'; self::$rules['password_confirmation'] = ''; } }

You would just add code like that anywhere in the model in question.
