php-Kohana ORM和验证,有问题

试图通过适用于Kohana 3.2的ORM进行验证.

目前,我有我的模特：

<?php defined('SYSPATH') or die('No direct access allowed.');

class Model_Brand extends ORM {

    protected $_has_many = array('models' => array());

    protected $_rules = array(
        'name' => array(
            'not_empty' => NULL,
            'min_length' => array(3),
            'max_length' => array(20),
        ),
        'sku' => array(
            'not_empty' => NULL,
            'min_length' => array(3),
            'max_length' => array(6),
        ),

    );

}

这是我的控制器：

<?php defined('SYSPATH') or die('No direct script access.');

class Controller_Brand extends Controller_Layout {

    public function action_view()
    {
        $brands = ORM::factory('brand')->find_all();
        $this->template->title = __('Brands');
        $this->template->content = View::factory('brands/view' );
        $this->template->content->set('brands', $brands);
    }

    public function action_edit()
    {
        if($_POST)
        {
            try
            {
                $brand = ORM::factory('brand', $this->request->param('id'));
                $brand->values($_POST);

                if($brand->check())
                {
                    $brand->update();
                    $brand->save();

                    //go to brand/views
                }

            }
            catch (ORM_Validation_Exception $e)
            {
                //pass errors to brand/edit
            }
        }
        else
        {
            $brand = ORM::factory('brand', $this->request->param('id'));

            $this->template->title = __('Edit Brand');
            $this->template->content = View::factory('brands/edit' );
            $this->template->content->set('brand', $brand);
        }
    }
}

我什至还没有到错误部分.我遇到的问题是它可以对任何输入进行验证,而不能使用模型中的规则.同样,如果有人可以告诉我如何设计这样的更新操作,将大有帮助.谢谢.

解决方法:

这就是我进行模型验证的方式,我觉得这是最简单明了的.

首先,我在rules()方法中设置规则：

<?php defined('SYSPATH') or die('No direct access allowed.');

class Model_Brand extends ORM {

    public function rules()
    {
        return array(
            'name' => array(
                array('not_empty'),
                array('min_length', array(':value', 3)),
                array('max_length', array(':value', 20)),
            )
            'sku' => array(
                array('not_empty'),
                array('min_length', array(':value', 3)),
                array('max_length', array(':value', 6)),
            )
        );
    );
}

这就是我管理编辑操作的方式：

public function action_edit()
{
    $brand = ORM::factory('brand', $this->request->param('id'));

    if (!$brand->loaded())
    {
        throw new Kohana_Exception('Brand not found.');
    }

    $this->template->title = __('Edit Brand');
    $this->template->content = View::factory('brands/edit')
        ->set('brand', $brand)
        ->bind('errors', $errors);

    if ($this->request->method() === Request::POST)
    {
        try
        {
            $brand->values($this->request->post());
            $brand->save();

            // Success! You probably want to set a session message here.

            $this->request->redirect($this->request->uri());
        }
        catch(ORM_Validation_Exception $e)
        {
            // Fail!

            $errors = $e->errors('brand');
        }
    }
}

在我看来：

<?php if ($errors) {?>
    <!-- display errors here -->
<?php } ?>

<?php echo Form::open()?>
    <fieldset>

        <div class="field">
            <?php echo 
                Form::label('name', __('Name')),
                Form::input('name',  $brand->name)
            ?>
        </div>

        <?php echo Form::submit('save', 'Save')); ?>
    </fieldset>
<?php echo Form::close()?>

正如您在视图中看到的那样,我没有进行任何条件检查以查看在表单字段中显示什么,因为这是由模型中的数据管理的,而模型是由控制器管理的.

希望对您有所帮助,请问是否需要进一步说明.
