描述

生成并持久化种子数据。源于 Soyuka 的种子包：https://github.com/soyuka/SeedBundle

配置

ds_restauration_seed:
  prefix: 'seed' # Command prefix "seed:yourseedname"
  directory: 'Seeds' # Default seed path: Bundle/Seeds
  separator: ':'
  seed_order: # Order to load seeds in, lowest loads first.  Any seed not in the list defaults to an order of 0
    seed1: -1
    seed2: 1
  seed_bundle: # Order to load bundles in, lowest loads first.  Any bundles not in the list defaults to an order of 0
    bundle1: -1
    bundle2: 1

构建种子

Seed 类是一个 Command，并且

• 必须扩展 DsRestauration\SeedBundle\Command\Seed
• 类名必须以 Seed 结尾
• 必须在配置方法中调用 setSeedName

<?php

namespace AcmeBundle\ISOBundle\Seeds;

use DsRestauration\SeedBundle\Command\Seed;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;

use Symfony\Component\Yaml\Parser;
use AcmeBundle\ISOBundle\Entity\Country;

class CountrySeed extends Seed
{

    protected function configure()
    {
        //The seed won't load if this is not set
        //The resulting command will be {prefix}:country
        $this->setSeedName('country');
        //Needed if you want to load seeds by bundle
        $this->setBundleName('geo');

        parent::configure();
    }

    public function load(InputInterface $input, OutputInterface $output){

        //Doctrine logging eats a lot of memory, this is a wrapper to disable logging
        $this->disableDoctrineLogging();

        //Access doctrine through $this->doctrine
        $countryRepository = $this->doctrine->getRepository('AcmeISOBundle:Country');

        $yaml = new Parser();

        //for example, using umpirsky/country-list (lazy yaml)
        $countries = $yaml->parse(file_get_contents('vendor/umpirsky/country-list/country/cldr/fr/country.yaml'));

        foreach ($countries as $id => $country) {

            if($countryRepository->findOneById($id)) {
                continue;
            }

            $e = new Country();

            $e->setId($id);
            $e->setName($country);

            //Doctrine manager is also available
            $this->manager->persist($e);

            $this->manager->flush();
        }

        $this->manager->clear();
    }
}

加载种子

SeedBundle 提供了两个默认命令和每个创建的种子一个命令。以前面的示例为例，我将有

app/console seed:load #calls the load method of every seed
app/console seed:unload #calls the unload method of every seed
app/console seed:country

全局的 seed:load 和 seed:unload 允许您在一个命令中运行多个种子。当然，您可以跳过种子 app/console seed:load --skip Town，也可以指定一个 app/console seed:load Country。有关更多信息，请使用 app/console seed:load --help。

种子顺序

种子顺序在配置文件中定义。顺序最低的种子先加载。任何未定义顺序的种子默认为顺序 0（将首先加载）。

包顺序

与种子顺序类似，包顺序也在配置文件中定义。顺序最低的包先加载。任何未定义顺序的包默认为顺序 0（将首先加载）。

按包/加载种子

可以使用 seed:load 的 --bundle 或 -bn 选项完成（seed:load --bundle geo --bundle params）。在这个例子中，只有那些将包定义为 'geo' 或 'params' 的种子会被加载。

仅加载特定种子

可以使用 seed:load 的 --seed 或 -s 选项完成（seed:load --seed countries --seed regions）。在这个例子中，只有那些将种子定义为 'countries' 或 'regions' 的种子会被加载。

跳过种子

可以使用 '--skip' 参数跳过一个或多个种子

跳过包

可以使用 '--skip-bundle' 参数跳过一个或多个包
