Question

这是我的用户控制器

public function action_create_student(){

    $view = View::forge('admin/users/create_student');

    if (Input::method() == 'POST')
    {   
        $val = Model_User::validate('create');

if ($val->run())
        {
            $newuser = Model_User::forge(array(
                'username'=> Input::post('username'),
                'firstname' =>Input::post('firstname'),
                'middlename'=> Input::post('middlename'),
                'lastname'=> Input::post('lastname'),
                'password'=> Auth::instance()->hash_password(Input::post('password')),
                'phone_number'=> Input::post('phone_number'),
                'group'=> Input::post('group'),
                'email'=> Input::post('email'),
                'course' =>Input::post('course'),
            ));
            $useruser = Model_Student::forge(array(
                'course' =>Input::post('course'),
                'user_id' =>Input::post('user_id'),
            ));
            $useruser->save();
            $newuser->save();

我想添加用户，我希望user_id（外键）等于用户表中的id（主键）

<?php
class Model_User extends \Orm\Model
{

protected static $_properties = array(
    'id',
    'username',
    'password',
    'firstname',
    'middlename',
    'lastname',
    'phone_number',
    'group',
    'email',
    'created_at',
    'updated_at',

);
protected static $_has_one = array(
    'student' => array(
        'model_to' => 'Model_Student',
        'key_from' => 'id',
        'key_to' => 'user_id',
        'cascade_delete' => true,
    ),
);


// public function get_full_name () {
//  return $this->'firstname' . ' ' . $this->'lastname';
//  static::method_exists(object, method_name());
// }
protected static $_observers = array(
    'Orm\Observer_CreatedAt' => array(
        'events' => array('before_insert'),
        'mysql_timestamp' => false,
    ),
    'Orm\Observer_UpdatedAt' => array(
        'events' => array('before_save'),
        'mysql_timestamp' => false,
    ),
);


public static function validate($factory)
{
    $val = Validation::forge($factory);
    $val->add_field('username', 'Username', 'required|max_length[50]');
    $val->add_field('password', 'Password', 'required|max_length[255]');
    $val->add_field('firstname', 'Firstname', 'required|max_length[50]');
    $val->add_field('middlename', 'Middlename', 'required|max_length[255]');
    $val->add_field('lastname', 'Lastname', 'required|max_length[255]');
    $val->add_field('phone_number', 'Phone Number', 'required|valid_string[numeric]');
    $val->add_field('group', 'Group', 'required|valid_string[numeric]');
    $val->add_field('email', 'Email', 'required|valid_email|max_length[255]');
    return $val;
}
}

    $val->add_field('user_id', 'User_id',  'required|valid_string[numeric]');
    return $val;
}
}

帮我摆脱这个需要帮助谢谢:)）

Answer 1

在您的控制器中，您只需执行

$newuser->student = $useruser;
$newuser->save();

而不是

$newuser->save();
$useruser->save();

如果您正确设置了关系，那么ORM会在保存时自动为您填充密钥。基本代码示例可在文档中找到：http://fuelphp.com/docs/packages/orm/relations/has_one.html#/has_one

Answer 2

现在我将回答我的问题：）

  $newuser = Model_User::forge(array(
                'username'=> Input::post('username'),
                'firstname' =>Input::post('firstname'),
                'middlename'=> Input::post('middlename'),
                'lastname'=> Input::post('lastname'),
                'password'=> Auth::instance()->hash_password(Input::post('password')),
                'phone_number'=> Input::post('phone_number'),
                'group'=> Input::post('group'),
                'email'=> Input::post('email'),
                'course' =>Input::post('course'),
            ));
            $newuser->student = Model_Student::forge(array(
                'course' =>Input::post('course'),
            ));

            if($newuser->save()){
                Session::set_flash('success', e('Added user'));
                Response::redirect('admin/users');
            }

您只需将该字段保存在学生中，但user_id除外，当你使用orm加入它时它会自动保存。
