如何在Doctrine 2.0中编写UNION（union使用教程）
如何在Doctrine 2.0中编写此SQL查询（并获取结果）？
(SELECT 'group' AS type,CONCAT(u.firstname," ",u.surname) as fullname,g.name AS subject,user_id,who_id,group_id AS subject_id,created
FROM group_notification
JOIN users u ON(who_id = u.id)
JOIN groups g ON(group_id = g.id)
)
UNION
(SELECT 'event' AS type,e.name AS subject,event_id AS subject_id,created
FROM event_notification
JOIN users u ON(who_id = u.id)
JOIN events e ON(event_id = e.id)
)
ORDER BY created
c# – 如何在Dynamic Linq中编写String.Contains
var q = obj.Where("message.Contains('hello')");
我知道它适用于
var q = obj.Where(o => o.message.Contains('hello'));
但我正在寻找动态的linq解决方案
谢谢.
解决方法
var q = obj.Where("message.Contains(@0)","hello");
docker Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/
利用docker构建时，报错
+ docker pull maven:3-alpine Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post http://%2Fvar%2Frun%2Fdocker.sock/v1.40/images/create?fromImage=maven&tag=3-alpine: dial unix /var/run/docker.sock: connect: permission denied script returned exit code 1解决方案
启动docker或者重启docker之后
cd /var/run
sudo chmod 666 docker.sock
docker: Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run
问题描述：
ubuntu 18.04 docker拉取镜像时出错
docker: Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post http://%2Fvar%2Frun%2Fdocker.sock/v1.24/containers/create: dial unix /var/run/docker.sock: connect: permission denied.
原因分析：
非root，所以权限不足
解决方案：
sudo gpasswd -a $(whoami) docker #将当前用户添加至docker用户组
newgrp docker #更新docker用户组
doctrine2 – Symfony / Doctrine UnitTests with SQLite memory DB
我想测试所有底层,但我不想用测试弄乱我的数据库.我不想使用模拟ups,而是使用内存中的sqlite数据库,我可以在其中设置测试场景以检查所有修改.
我发现了很多关于如何使用doctrine 1.x做到这一点的提示,但它们不再起作用了.
所以我想要这样的东西：
class BlahblahTest extends WebTestCase {
public function testXXXYYY() {
// 1. Setup a new database with sqlite:memory:
// 2. create the database and all tables according the entities in my project
$this->createTestScenario(); // 3.
$crawler = $this->client->request('GET','/testpage'); // 4.
// 5. Lots of checks against the database and / or the $crawler data
}
}
有机会获得这项工作吗？

为此你应该添加
# app/config/config_test.yml
doctrine:
dbal:
default_connection: default
connections:
default:
driver: pdo_sqlite
path: %kernel.cache_dir%/test.db
到你的测试配置(对我来说是config_test.yml)
您应该能够根据文档将其更改为内存
http://docs.doctrine-project.org/projects/doctrine-
dbal/en/latest/reference/configuration.html#pdo-sqlite
memory (boolean): True if the sqlite database should be in-memory (non-persistent). Mutually exclusive with path. path takes precedence.
所以配置应该是
# app/config/config_test.yml
doctrine:
dbal:
default_connection: default
connections:
default:
driver: pdo_sqlite
memory: true
