Laravel 4继承的属性为null

我有一个模型,它继承自Toddish \ Verify Laravel包(https://github.com/Toddish/Verify-L4/blob/master/src/Toddish/Verify/Models/User.php

我想要做的就是添加一些属性:

use Toddish\Verify\Models\User as VerifyUser;

class User extends VerifyUser
{
    public function __construct (array $attributes = array()) {
        parent::__construct($attributes);
        $this->fillable = array_merge ($this->fillable, array(
            'salutation', 'title', 'firstname', 'lastname', 'phonenumber', 'mobilenumber'
        ));
    }
}

当我进行测试时:

class UserTest extends TestCase {

    public function testUserCreation () {
        $user = User::create(
            [
                'username' => 'testusername',
                'email' => 'email@test.com',
                'password' => 'testpassword',
                'salutation' => 'MrTest',
                'title' => 'MScTest',
                'firstname' => 'Testfirstname',
                'lastname' => 'Testlastname',
                'phonenumber' => 'testPhoneNumber',
                'mobilenumber' => 'testMobileNumber',
            ]
        );

        $this->assertEquals($user->salutation, 'MrTest');
        $this->assertEquals($user->title, 'MScTest');
        $this->assertEquals($user->firstname, 'Testfirstname');
        $this->assertEquals($user->lastname, 'Testlastname');
        $this->assertEquals($user->phonenumber, 'testPhoneNumber');
        $this->assertEquals($user->mobilenumber, 'testMobileNumber');
    }
}

我得到以下内容:

1) UserTest::testUserCreation
Failed asserting that 'MrTest' matches expected null.

所有断言都返回null。但我检查了数据库列。那么为什么该属性为null?

编辑:

如果我交换断言参数:

$this->assertEquals('MrTest', $this->salutation);

我明白了:

ErrorException: Undefined property: UserTest::$salutation

答案 0 :(得分:2)

您需要将可填写覆盖移动到parent::__construct($attributes);

的调用之上

成功:

public function __construct (array $attributes = array()) {
    $this->fillable = array_merge ($this->fillable, array(
        'salutation', 'title', 'firstname', 'lastname', 'phonenumber', 'mobilenumber'
    ));
    parent::__construct($attributes);
}

这是因为主Model类构造函数使用fillable数组,因此需要在调用构造函数之前设置它。
