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）。我一直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 ***/
$manager->flush(); //Upload the data to the database.
}
决定重构它，我认为我的结果可能对做类似事情的其他人有用。我相信有办法改进它（我很高兴听到他们！）我相信会有很多人已经想到自己做类似的事情，但如果它对你有用，请随时使用它:)
你真的应该看看Jordi Boggiano（写作曲家的人）nelmio/alice！
通过深入研究这篇博客文章，了解设置灯具是多么简单，而无需在使用 Alice 的灯具课程中无休止地重复自己。
首先，
我在类中添加了一个名为createFixture（）的方法：
public function createFixture($code, $example, $lang) {
$codeExample = new codeExample();
$codeExample->setlang($lang);
$codeExample->setcodeExample($code);
$exampleFixture = (empty($example)) ? $code : $example;
$codeExample->settextExample($exampleFixture);
return $codeExample;
}
然后剩下的就是把固定装置放进去。如您所见，重复的代码大大减少：
/*** 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夹具重写一点，但原理是相同的。
