Laravel/Ardent/用户模型编辑+保存 [英] Laravel/Ardent/User model editing + saving

问题描述

在laravel/ardent中用密码编辑用户模型的预期方法是什么?我的问题是，我不想在正确验证用户输入之前从数据库加载实际的用户模型.当我将密码字段保留为空时，验证显然会失败，因为需要密码.这是我当前的后期编辑操作:

what is the intended way to edit a user model with password in laravel/ardent? My problem is, that I do not want to load the actual user model from the db before the user input is validated correctly. Validation obviously fails when I leave the password field empty, because a password is required. This is my current post-edit-action:

public function postEdit($id)
{
    // ardent autohydrates this model
    $newUser = new User;

    // validation fails
    if(!$newUser->validate())
        return Redirect::action('UsersController@getEdit', $id)
            ->with('error', Lang::get('Bitte Eingabe überprüfen'))
            ->withErrors($newUser->errors())
            ->withInput(Input::except('password'));

    // load model from db
    $exUser = User::find($id);
    if(!$exUser->exists)
        return Response::make('No such user', 500);

    // save model, ardent autohydrates again?
    if($exUser->save())
        return Redirect::action('UsersController@getShow', $id)
            ->with('success', Lang::get('Änderungen gespeichert'));
    else
        return Redirect::action('UsersController@getEdit', $id)
            ->with('error', Lang::get('Bitte Eingabe überprüfen'))
            ->withErrors($newUser->errors())
            ->withInput(Input::except('password'));
}

这似乎是很多代码(+无法正常工作)，我无法找到这种情况的示例

this seems like an awful lot of code (+ it is not working), I was unable to find an example for this situation

推荐答案

好吧，我自己解决了这个问题，因为这不是一个非常活跃的话题.

Ok, solved it myself, seeing as this is not a very active topic.

问题在于结合了热情的自动补水功能和唯一的保留旧密码的要求(如果没有提供新密码的话).因为在validate()和save()上热切自动补水，所以也没有办法防止空密码自动补水.首先，我尝试更改Input数组并用旧密码覆盖它，但是随后我只是为用户模型关闭了自动补水功能:

The problem was combining ardents autohydration feature and the unique requirement to retain the old password, if no new one is given. Because ardent autohydrates on validate() AND save(), there was no way to prevent autohydrating empty passwords too. First, I tried to change the Input array and overwrite it with the old password, but then I simply turned off the autohydration for the user model:

class User extends Ardent implements UserInterface, RemindableInterface {

    public $forceEntityHydrationFromInput = false;
    public $autoHydrateEntityFromInput = false;

这是对POST的编辑操作:

This is the edit action on POST:

public function postEdit($id)
{
    // manually insert the input
    $user = new User(Input::all());

    // validate the user with special rules (password not required)
    if($user->validate(User::$updateRules)) {

        // get user from database and fill with input except password
        $user = User::find($id);
        $user->fill(Input::except('password'));

        // fill in password if it is not empty
        // will flag the pw as dirty, which will trigger rehashing on save()
        if(!empty(Input::get('password')))
            $user->password = Input::get('password');

        if($user->save())
            return Redirect::action('UsersController@getIndex')
                ->with('success', Lang::get('Änderungen gespeichert'));
    }

    return Redirect::action('UsersController@getEdit', $id)
        ->with('error', Lang::get('Bitte Eingaben überprüfen'))
        ->withErrors($user->errors())
        ->withInput(Input::except('password'));
}
