小编Mat*_*teo的帖子

我试图理解Lisp-1和Lisp-2之间的区别以及它与Clojure的关系,但我仍然不理解.任何人都可以开导我吗？

我刚刚升级到symfony 2.7,并且有令人讨厌的行为.

我的config.yml中的某些连接是可选项,并描述了不打算在每个prod实例中使用的外部数据库.

在执行缓存时:清除,现在似乎检查了每个连接,即使我不希望它们在特定服务器上处于活动状态.

设置--no-warmup选项时,问题发生的时间是一半

php app/console cache:clear --env=prod --no-warmup --verbose

自从我Symfony 2更新到2.7.我得到了很多过时erors的PHPUnit和console(信息是明确的现在).

ProjectX\ApiBundle\Tests\Controller\SectionsControllerTest::testPostDebug()
The twig.form.resources configuration key is deprecated since version 2.6 and will be removed in 3.0. Use the twig.form_themes configuration key instead.

知道如何禁用它们吗？

我创建服务但它不起作用

services:
    redirectionListener:
          class: Front\EcommerceBundle\Listener\RedirectionListener
          arguments: ["@service_container","@session"]
          tags:
            - { name: kernel.event_listener, event: kernel.request, method: onKernelRequest }

这是我的课

namespace Front\EcommerceBundle\Listener;

use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\HttpFoundation\Session\Session;
use Symfony\Component\HttpFoundation\RedirectResponse;
use Symfony\Component\HttpKernel\Event\GetResponseEvent;

class RedirectionListener
{
    public function __construct(ContainerBuilder $container, Session $session)
    {
        $this->session = $session;
        $this->router = $container->get('router');
        $this->securityContext = $container->get('security.context');
    }

    public function onKernelRequest(GetResponseEvent $event)
    {
        $route = $event->getRequest()->attributes->get('_route');

        if ($route == 'livraison' || $route == 'validation') {
            if ($this->session->has('panier')) {
                if (count($this->session->get('panier')) == 0)
                    $event->setResponse(new RedirectResponse($this->router->generate('panier')));
            }

            if (!is_object($this->securityContext->getToken()->getUser())) {
                $this->session->getFlashBag()->add('notification','Vous devez …

FOSUserBundle可以与symfony 3一起使用吗？无法在其网站上看到有关该信息的任何信息.

我刚刚安装了Symfony 3的新副本,确实composer update已经尝试安装FOSUserBundle.

在控制台上接收不太友好的东西;)

composer require friendsofsymfony/user-bundle

  Problem 1
    - Conclusion: remove symfony/symfony v3.0.0
    - Conclusion: don't install symfony/symfony v3.0.0
    - friendsofsymfony/user-bundle v1.3.0 requires symfony/security-bundle 2.1.* -> satisfiable by symfony/security-bundle[v2.1.0, v2.1.1, v2.1.10, v2.1.11, v2.1.12, v2.1.13, v2.1.2, v2.1.3, v2.1.4, v2.1.5, v2.1.6, v2.1.7, v2.1.8, v2.1.9].

我需要查询所有记录类型,而不进行任何过滤.我试过两种方法:

let query = CKQuery(recordType: "Pm", predicate: nil)
let query = CKQuery(recordType: "Pm", predicate: NSPredicate(format: ""))

我收到了错误:

'NSInvalidArgumentException',原因:'无法解析格式字符串""'

怎么做？

我想在我RandomController::indexAction()的XML响应中返回:

return new Response($this->renderView(
    'AcmeRandomBundle:Random:index.xml.twig',
    array(
        'randomParameter' => $randomParameter
    )
));

那样的地方index.xml.twig:

<?xml version="1.0" encoding="UTF-8"?>
<randomTag>
    {{ randomParameter }}
</randomTag>

当我想在firefox中打开这个动作时,我会进入firebug:

<html>
   <body>
    <randomTag>
        randomValue
    </randomTag>
   </body>
</html>

如何返回正确的XML响应？

我必须遵循实体:

/**
 * ProductService
 *
 * @ORM\Table(name="sf_products_services")
 * @ORM\Entity(repositoryClass="Evo\BackendBundle\Entity\ProductServiceRepository")
 */
class ProductService
{
    [...]

    /**
     * @var string
     *
     * @ORM\Column(name="name", type="string", length=150)
     */
    protected $name;

    [...]

如何读取$ name属性的"length"值？我读过我可以使用doctrine元数据,但我没有找到任何关于如何使用它以及如何读取这些数据的信息.

使用Symfony 2.7,您可以使用方法自定义EntityType类中的表单名称getName()
.现在不推荐使用.是否有另一种方法可以使用Symfony 3.0？
我有自定义原型entry_rows的集合,我需要以不同的形式使用.
由于行的名称基于表单的名称,因此我需要更改后者才能使用不同的表单.

我在Windows 2008 R2上运行带有Erlang OTP 17.1的RabbitMQ v3.3.5.我的Dev和QA环境是独立的.我的登台和生产环境是集群的.

我发现RabbitMQ服务正在运行时经常出现这个问题,RabbitMQ管理控制台正在查看所有内容,但是当我尝试从命令行运行rabbitmqctl时,它失败并显示节点已关闭的错误(在本地和在远程服务器).

如果我重新启动Windows服务,则会解决此问题.

我在RabbitMQ错误日志中看不到任何错误消息.最后一条消息表明节点已启动.

下面是我最近在登台窗口集群的节点2上遇到的问题的示例输出:

PS C:\Program Files (x86)\RabbitMQ Server\rabbitmq_server-3.3.5\sbin> .\rabbitmqctl.bat status
Status of node rabbit@MYSERVER2 ...
Error: unable to connect to node rabbit@MYSERVER2: nodedown

DIAGNOSTICS
===========

attempted to contact: [rabbit@MYSERVER2]

rabbit@MYSERVER2:
  * connected to epmd (port 4369) on MYSERVER2
  * epmd reports: node 'rabbit' not running at all
                  no other nodes on MYSERVER2
  * suggestion: start the node

current node details:
- node name: rabbitmqctl2199771@MYSERVER2
- home dir: C:\Users\RabbitMQ
- cookie hash: mn6OaTX9mS4DnZaiOzg8pA==

此时我重新启动RabbitMQ服务,然后再试一次 …
