有没有更简单的方法来设置学说中的装置？

以前，在创建夹具文档以构建网站时（用于测试或没有CMS的网站）。我总是按照示例文档中所示的方式进行操作。因此，灯具页面将有很多重复的代码。像这样（这是一个简短的！）：

class codeExampleFixtures  extends AbstractFixture implements OrderedFixtureInterface
{
/**
 * {@inheritDoc}
 */
public function load(ObjectManager $manager)
{
    /*** Begin data fixture ***/
    $code1 = '<p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.</p><p>Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur.</p>';        
    // The $exampleX variable can be left empty if not needed.
    $example1 = '<p>In this example. The code is different for the example itself.</p><p>Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur.</p>';
    $lang1 = 'html'; // choices are 'html', 'css' and 'js'

    // Do not edit anything else in this fixture.
    $codeExample1 = new codeExample();
    $codeExample1->setlang($lang1);
    $codeExample1->setcodeExample($code1);
    $exampleFixture1 = (empty($example1)) ? $code1 : $example1;
    $codeExample1->settextExample($exampleFixture);
    $manager->persist($codeExample1);
    $this->setReference('ce1', $codeExample1);
    /*** End data fixture ***/

    /*** Begin data fixture ***/
    $code2 = '<p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.</p><p>Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur.</p>';        
    // The $exampleX variable can be left empty if not needed.
    $example2 = Null;
    $lang2 = 'css'; // choices are 'html', 'css' and 'js'

    // Do not edit anything else in this fixture.
    $codeExample2 = new codeExample();
    $codeExample2->setlang($lang2);
    $codeExample2->setcodeExample($code2);
    $exampleFixture2 = (empty($example2)) ? $code2 : $example2;
    $codeExample2->settextExample($exampleFixture2);
    $manager->persist($codeExample2);
    $this->setReference('ce2', $codeExample2);
    /*** End data fixture ***/

    $manager->flush(); //Upload the data to the database.
}

我决定重构它，我认为我的结果可能对其他做类似事情的人有用。我敢肯定有很多方法可以改善它（我很高兴听到他们的声音！），我敢肯定会有很多人已经考虑过自己做类似的事情，但是如果对您有用的话，请随意使用它：）

首先，我在类中添加了一个名为createFixture（）的方法：

public function createFixture($code, $example, $lang) {
    $codeExample = new codeExample();
    $codeExample->setlang($lang);
    $codeExample->setcodeExample($code);
    $exampleFixture = (empty($example)) ? $code : $example;
    $codeExample->settextExample($exampleFixture);
    return $codeExample;
}

然后剩下的就是将固定装置放进去。如您所见，大大减少了重复的代码：

/*** Begin data fixture ***/
    $fixture = $this->createFixture(
        "<p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor 
        incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud 
        exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.</p>
        <p>Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu 
        fugiat nulla pariatur.</p>", 
        "<p>In this example. The code is different from the example itself.</p>
        <p>Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu 
        fugiat nulla pariatur.</p>", 
        "html"
    );
    /* in order to reference this later, specify a simple and uniqe key for this fixture */
    $this->setReference('ce1', $fixture);
    $manager->persist($fixture);
    /*** End data fixture ***/

    /*** Begin data fixture ***/
    $fixture = $this->createFixture(
        "<p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor 
        incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud 
        exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.</p>
        <p>Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu 
        fugiat nulla pariatur.</p>", 
        "", 
        "css"
    );
    /* in order to reference this later, specify a simple and uniqe key for this fixture */
    $this->setReference('ce2', $fixture);
    $manager->persist($fixture);
    /*** End data fixture ***/

显然，您必须为每种不同类型的灯具重新编写一些代码，但是原理是相同的。
