Laravel 4 - 更新子表“persons”的值，同时更新父表“users”的值

Question

我正在使用框架 Laravel。

我有 2 个表（用户和人员）。我想更新子表“persons”的值，同时更新父表“users”的值。我有一个 edit.blade.php，我在其中创建了我的表单，我将数据库中的值存储在输入字段中。

表用户

CREATE TABLE IF NOT EXISTS `festival_aid`.`users` (
  `user_id` BIGINT NOT NULL AUTO_INCREMENT,
  `user_username` VARCHAR(45) NOT NULL,
  `user_email` VARCHAR(45) NOT NULL,
  `user_password` CHAR(32) NOT NULL,
  `user_salt` CHAR(32) NOT NULL,
  `user_created` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
  `user_modified` TIMESTAMP NULL,
  `user_deleted` TIMESTAMP NULL,
  `user_lastlogin` TIMESTAMP NULL,
  `user_locked` TIMESTAMP NULL,
  `user_token` VARCHAR(128) NULL,
  `user_confirmed` TIMESTAMP NULL,
  PRIMARY KEY (`user_id`, `person_id`),
  UNIQUE INDEX `user_email_UNIQUE` (`user_email` ASC),
  INDEX `fk_users_persons1_idx` (`person_id` ASC),
  CONSTRAINT `fk_users_persons1`
    FOREIGN KEY (`person_id`)
    REFERENCES `festival_aid`.`persons` (`person_id`)
    ON DELETE CASCADE
    ON UPDATE NO ACTION)
ENGINE = InnoDB;

桌人

CREATE TABLE IF NOT EXISTS `festival_aid`.`persons` (
  `person_id` BIGINT NOT NULL AUTO_INCREMENT,
  `person_firstname` VARCHAR(45) NULL,
  `person_surname` VARCHAR(45) NULL,
  `person_created` TIMESTAMP NOT NULL,
  `person_modified` TIMESTAMP NULL,
  `person_deleted` TIMESTAMP NULL,
  PRIMARY KEY (`person_id`))
ENGINE = InnoDB;

编辑操作

public function edit($person_id)
    {
        $person = Person::find($person_id);
        //$person = Person::with('user')->orderBy('person_id');

        return View::make('persons.edit')
            ->with('person', $person);
    }

更新操作

public function update($person_id)
    {
        $rules = array();
        $validator = Validator::make(Input::all(), $rules);

        if ($validator->fails()) {
            return Redirect::to('persons/' . $person_id . '/edit')
                ->withErrors($validator);
        } else {
            //$person = Person::with('user')->orderBy('person_id');
            $person = Person::find($person_id);

            $person->person_firstname      = Input::get('person_firstname');
            $person->person_surname      = Input::get('person_surname');
            //$person->user->user_username = Input::get('user_username');
            //$person->user->user_surname = Input::get('user_surname');
            //$person->user->user_email = Input::get('user_email');

            $person->save();

            Session::flash('message', 'Successfully updated user!');
            return Redirect::to('persons');
        }
    }

编辑视图

 <legend>Edit {{ $person->person_firstname }}</legend>

    {{ HTML::ul($errors->all()) }}

    {{ Form::model($person->user, array('route' => array('persons.update', $person->person_id), 'method' => 'PUT')) }}

    <div class="form-group">
        {{ Form::label('firstname', 'Firstname') }}
        {{ Form::text('person_firstname', $value = $person->person_firstname, array('class'=>'form-control', 'placeholder' => 'Firstname')) }}
    </div>

    <div class="form-group">
        {{ Form::label('surname', 'Surname') }}
        {{ Form::text('person_surname', $value = $person->person_surname, array('class'=>'form-control', 'placeholder' => 'Surname')) }}
    </div>

    <div class="form-group">
        {{ Form::label('username', 'Username') }}

        {{ Form::text('user_username', $value = $person->user->user_username, array('class'=>'form-control', 'placeholder' => 'Username')) }}
    </div>

    <div class="form-group">
        {{ Form::label('email', 'Email') }}
        {{ Form::text('user_email', $value = $person->user->user_email, array('class' => 'form-control')) }}
    </div>

    <div class="form-group">
        {{ Form::label('Password') }}
        {{ Form::password('user_password', array('class'=>'form-control', 'placeholder' => 'Password')) }}
    </div>

    {{ Form::submit('Edit the User!', array('class' => 'btn btn-primary')) }}

    {{ Form::close() }}
@stop

用户迁移

Schema::table('users', function(Blueprint $table)
        {
        $table->increments('user_id');
            $table->string('user_email');
            $table->timestamp('user_created');
            $table->timestamp('user_modified');
            $table->timestamp('user_deleted');
            $table->timestamp('user_lastlogin');
            $table->timestamp('user_locked');

            $table->foreign('person_id')
                ->references('id')->on('persons')
                ->onDelete('cascade');
        });

人员迁移

public function up()
    {
        Schema::table('persons', function(Blueprint $table)
        {
            $table->increments('person_id');

            $table->string('person_firstname');
            $table->string('person_surname');
        });
    }

模型用户

class User extends Eloquent  {

    protected $primaryKey = 'user_id';

    public function persons()
    {
        return $this->hasOne('Person');
    }

    public $timestamps = false;
}

模范人物

class Person extends Eloquent {

    protected $table = 'persons';

    protected $primaryKey = 'person_id';

    public function users()
    {
        return $this->belongsTo('User');
    }

    public $timestamps = false;
}

我的问题是更新操作只更新了 person 表中的值，而不是 users 表中的值。

Answer 1

根据 Laravel 文档，在更新 belongsTo 关系时，您可以使用 associate 方法。此方法将在子模型上设置外键：

$person->users()->associate($person);

$person->save();

参考：

http://laravel.com/docs/eloquent#inserting-related-models

Answer 2

我找到了解决办法：

公共函数更新（$person_id） {

    $rules = array();
    $validator = Validator::make(Input::all(), $rules);

    if ($validator->fails()) {
        return Redirect::to('persons/' . $person_id . '/edit')
            ->withErrors($validator);
    } else {

        $user = User::find($person_id); // <= ADD THIS
        $person = Person::find($person_id);

        $person->person_firstname      = Input::get('person_firstname');
        $person->person_surname      = Input::get('person_surname');

        $user->user_username = Input::get('user_username'); // <= ADD THIS
        $user->user_email = Input::get('user_email'); // <= ADD THIS

        $person->save();
        $user->save();

        Session::flash('message', 'Successfully updated user!');
        return Redirect::to('persons');
    }
}
