如何加载 Yii 2 fixture？

Question

我使用一个简单的装置来填充测试数据库中的 table。但是当我尝试加载它时，检查完整性代码抛出异常 'Table not found: []'.

我的固定装置：

<?php

namespace tests\unit\fixtures;

use yii\test\ActiveFixture;

class IdentityDocumentFixture extends ActiveFixture
{
    public $modelClass = 'backend\modules\persons\models\IdentityDocument';
}

为了加载夹具，我使用来自@app/tests 的命令：yii fixture/load IdentityDocument

C:\php-projects\ais\tests\codeception\bin>yii fixture/load IdentityDocument
Fixtures namespace is:
        tests\unit\fixtures

Global fixtures will be used:

        1. yii\test\InitDb

Fixtures below will be loaded:

        1. IdentityDocument

Load above fixtures? (yes|no) [no]:yes

因此，我收到此错误消息：

Exception 'yii\base\InvalidParamException' with message 'Table not found: []' in C:\php-projects\ais\vendor\yiisoft\yii2\db\mssql\QueryBuilder.php:180

堆栈跟踪：

如何加载fixture？测试数据库存在，数据源配置正确

table的真名是tbl_identitydocument:

CREATE TABLE [dbo].[tbl_identitydocument](
    [ID] [int] IDENTITY(1,1) NOT NULL,
    [Name] [varchar](100) NOT NULL,
    [FISID] [int] NULL,
 CONSTRAINT [PK_tbl_identitydocument] PRIMARY KEY CLUSTERED 
(
    [ID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]

这里是模型IdentityDocument的方法tableName()：

public static function tableName()
{
    return '{{%identitydocument}}';
}

模型代码完整：

<?php

namespace backend\modules\persons\models;

use Yii;
use backend\modules\persons\Module;

/**
 * This is the model class for table "{{%identitydocument}}".
 *
 * @property integer $ID
 * @property string $Name
 * @property integer $FISID
 */
class IdentityDocument extends \yii\db\ActiveRecord
{
    /**
     * @inheritdoc
     */
    public static function tableName()
    {
        return '{{%identitydocument}}';
    }

    /**
     * @inheritdoc
     */
    public function rules()
    {
        return [
            [['Name'], 'required'],
            [['Name'], 'string'],
            [['FISID'], 'integer']
        ];
    }

    /**
     * @inheritdoc
     */
    public function attributeLabels()
    {
        return [
            'ID' => Module::t('ML', 'ID'),
            'Name' => Module::t('ML', 'Name'),
            'FISID' => Module::t('ML', 'FISID'),
        ];
    }
}

在调试器下我可以看到那个方法IdentityDocument::tableName() returns:

$tableNameTmp = IdentityDocument::tableName();

我看到$tableNameTmp等于{{%identitydocument}}（逐字，returns这个字符串）

在调试器下我可以看到以下内容。在classTestCase.php中有一个方法setUp():

/**
 * @inheritdoc
 */
protected function setUp()
{
    parent::setUp();
    $this->mockApplication();
    $this->unloadFixtures();
    $this->loadFixtures();
}

这里抛出异常：$this->unloadFixtures():

在屏幕截图中可以看到 initScript 引用了路径 @app/tests/fixtures/initdb.php 但是没有这样的文件.. 还有 schemas 数组包含单个元素 "".

我使用了@slinstj here - Run fixture/load User fails to load User data写的指令。在我的本地项目（高级模式和 MySQL rdbms）中，夹具已成功加载：

1 - 检查您是否为 yii\db\Connection:

设置了 tablePrefix 参数

'components' => [
    'db' => [
        'class' => '\yii\db\Connection',
        'dsn' => 'mysql:host=127.0.0.1;dbname=demo',
        'username' => 'root',
        'password' => '',
        'charset' => 'utf8',
        'tablePrefix' => 'tbl_', // <<<<<<<<
    ],
],

来自 docs 的更多信息：

$tablePrefix:

The common prefix or suffix for table names. If a table name is given as {{%TableName}}, then the percentage character % will be replaced with this property value. For example, {{%post}} becomes {{tbl_post}}.

或

2 - 设置 dataFile 路径：

根据this：

// In your IdentityDocumentFixture, set this:
public $dataFile = __DIR__ . '/path/to/your/data-file.php';
