[英]Composer and PSR-0
I have composer.json structure like this: 我有这样的composer.json结构:
"psr-0": {
"DatabaseSeeder\\": "app/database/seeds/"
},
I have files in app/database/seeds (Files here can be created dynamically so solution with "classmap": ["app/database/seeds"] doesn't work here bcs I have to always dump-autoload before seeding: 我在app / database / seeds中有文件(此处的文件可以动态创建,因此使用“ classmap”解决方案:[“ app / database / seeds”]在这里不起作用bcs我必须始终在播种前自动转储自动加载:
with structure like this: 具有这样的结构:
# DatabaseSeeder.php
namespace DatabaseSeeder;
use Doctrine\ORM\EntityManager;
class DatabaseSeeder implements Seeder {
/**
* Run the database seeds.
*
* @return void
*/
public function run(EntityManager $em)
{
$this->call('DatabaseSeeder\UserTableSeeder', $em);
}
private function call($class, $em)
{
$reflectionMethod = new \ReflectionMethod($class, 'run');
$reflectionMethod->invoke(new $class, $em);
}
After php composer.phar install and php composer.phar dump-autoload I cannot use in application for example in index.php 安装php composer.phar和php composer.phar dump-autoload之后,我无法在应用程序中使用,例如在index.php中
$object = new \DatabaseSeeder\DatabaseSeeder();
because I recieve error: Class DatabaseSeeder\\DatabaseSeeder does not exist WHY ?? 因为我收到错误:类DatabaseSeeder \\ DatabaseSeeder不存在,为什么? It should autoload class while initiating object.
它应该在启动对象时自动加载类。
First of all, you should make sure your index.php properly includes composer autoload. 首先,您应确保index.php正确包含composer自动加载。
<?php
include __DIR__ . '/vendor/autoload.php';
Then you need to validate your directory structure to be properly autoloaded. 然后,您需要验证目录结构以正确地自动加载。
If your PSR-0 configuration is 如果您的PSR-0配置是
"psr-0": {
"DatabaseSeeder\\": "app/database/seeds/"
},
then your directory structure should looks like: 那么您的目录结构应如下所示:
app/
database/
seeds/
DatabaseSeeder/
DatabaseSeeder.php
For more information about composer PSR-0 autoload, you can read composer schema documentation. 有关composer PSR-0自动加载的更多信息,您可以阅读composer 模式文档。 Hope this helps.
