修改为

default_config_hash: Q1nMi90W6YQxKzZAgJQw7Ag9U4JrsEUwkomF0lhvbIM
langcode: zh-hans
field_prefix: ''
服务器需要安装: rsyslog
启用drupal核心模块：syslog
在这里配置admin/config/development/logging日志前缀. 一般选择默认的就行， 如果有多个站点。可以第一个站点选择local0, 第二站点选择local1
LOG_LOCAL0
LOG_LOCAL1
LOG_LOCAL2
LOG_LOCAL3
LOG_LOCAL4
LOG_LOCAL5
LOG_LOCAL6
LOG_LOCAL7
配置rsyslog
vim /etc/rsyslog.d/50-default.conf
添加行：
local0.* /var/log/drupal.log
这里的local0和你上面的选择有关系.
重新启动rsyslog服务
service rsyslog restart
禁用db log模块
测试
1. 打开一个404页面
2. \Drupal::logger('debug_test')->notice('hello world');
实现效果为:
*.docker/ 解析到127.0.0.1
方便映射到对应的开发目录比如:
drupal9.docker/ 映射到 /User/you/www/drupal9
drupal10.docker/ 映射到 /User/you/www/drupal10
$ brew install dnsmasq
$ cd $(brew --prefix); echo 'address=/.docker/127.0.0.1' > etc/dnsmasq.conf
$ sudo cp -v $(brew --prefix dnsmasq)/homebrew.mxcl.dnsmasq.plist /Library/LaunchDaemons
$ sudo launchctl load -w /Library/LaunchDaemons/homebrew.mxcl.dnsmasq.plist
$ sudo mkdir /etc/resolver
$ sudo bash -c 'echo "nameserver 127.0.0.1" > /etc/resolver/dev'
在定义Entity的handlers中自定义views_data
* handlers = {
* "views_data" = "Drupal\mymodule\Entity\MymoduleViewsData",
创建MymoduleViewsData字段
<?php
namespace Drupal\mymodule\Entity;
use Drupal\views\EntityViewsData;
class MymoduleViewsData extends EntityViewsData {
/**
* {@inheritdoc}
*/
public function getViewsData() {
$data = parent::getViewsData();
$data['my_entity_type']['my_field'] = [
'title' => $this->t('test field'),
'help' => $this->t('test field'),
'field' => [
'id' => 'field_id',
],
];
return $data;
}
}
如果是已存在Entity可以这样
/**
* Implements hook_views_data().
*/
function mymodule_views_data() {
$data['my_entity_type']['my_field'] = [
'title' => $this->t('test field'),
'help' => $this->t('test field'),
'field' => [
'id' => 'field_id',
],
];
return $data;
}
在模块src/Plugin/views/field下面创建文件MyField.php
<?php
namespace Drupal\my_module\Plugin\views\field;
use Drupal\views\Plugin\views\field\FieldPluginBase;
use Drupal\views\ResultRow;
// 这里的field_id和上面的field_id对应
/**
* @ViewsField("field_id")
*/
class MyField extends FieldPluginBase {
/**
* {@inheritdoc}
*/
public function query() {}
/**
* {@inheritdoc}
*/
public function render(ResultRow $values) {
// 自定义输出.
$entity = $this->getEntity($values);
return $entity->label();
}
}
由于上次写的Entity扩展改起来比较复杂。并且也不是太好用。所以这次提供了一个简单的模块来实现这个功能，已经上传到Drupal.org
https://www.drupal.org/project/entity_expand
在很多时候比如写抓取API代码。一般像这种是通过cron去跑. 而cron一般是匿名用户. 如果直接用admin方式来测试可能会有很多的Bug. 就比如profile一般都需要加accessCheck(false). 所以在写类似代码的时候一定要加上这段方便测试
$switcher = \Drupal::service('account_switcher');
$switcher->switchTo(new \Drupal\Core\Session\AnonymousUserSession());
// 你的逻辑代码
// 结尾加上这句回到当前登陆用户.
$switcher->switchBack();
当我们想用后台跑一个命令的时候可能经常是这样使用的
$ drush mycommand &
这个命令只是在后台跑。当我们关掉ssh了以后，此进程就没有了. 随后了解到了nohup。 他还会生成一个.out的日志文件 使用方法
$nohup drush mycommand &
以前的Query可以理解为
// 获取一个Entity类型的Storage
$node_storage = \Drupal::entityTypeManager()->getStorage('node');
// 获取Query
$query = $node_storage->getQuery();
$query->condition('type', 'article');
$query->condition('channel.entity:taxonomy_term.checkout_status', 1);
$ids = $query->execute();
dpm($ids);
再来看一个多层链接的
$node_storage = \Drupal::entityTypeManager()->getStorage('node');
$query = $node_storage->getQuery();
$query->condition('type', 'article');
$query->condition('channel.entity:taxonomy_term.vehicle_type.entity:taxonomy_term.name', '汽车运输');
$ids = $query->execute();
dpm($ids);
在使用entity中有些事情比较繁琐, 比如
1. 获取关联的entity
$entity->get('field')->entity->toArray()
这里有一个弊端.如果entity已经被删除了或者entity不存在都会报错.
2. 获取多值的target_id, 需要有多步操作.
$ids = [];
if (!$entity->get('field')->isEmpty()) {
$ids = $entity->get('field')->getValue();
$ids = array_column($ids, 'target_id');
}
3. 获取多值的广本字段.也需要有多步操作
$values = [];
if (!$entity->get('field')->isEmpty()) {
$values = $entity->get('field')->getValue();
$values = array_column($values, 'value');
}
4. 获取lis字段的label
$value = '';
if ($entity->get('field')->isEmpty()) {
$allow_values = $entity->get('field')->getSetting('allowed_values');
$value = $allow_values[$entity->get('field')->value];
}
以下是一个简单扩展
<?php
namespace Drupal\mymodule;
use Drupal\Core\Entity\EntityInterface;
use Drupal\Core\Field\FieldItemListInterface;
/**
* entity helper.
*
* Class Entity
*/
class Entity {
/**
* @var EntityInterface
*/
private EntityInterface $entity;
/**
* init entity.
*
* Entity constructor.
* @param EntityInterface $entity
*/
public function __construct(EntityInterface $entity) {
$this->entity = $entity;
}
/**
* get field use custom.
*
* @param $field
* @return FieldItem
*/
public function get($field):FieldItem {
return new FieldItem($this->entity, $field);
}
/**
* bundle key
* node key is type
* profile key is profile_type
* @return false|string
*/
public function bundleKey() {
return $this->entity->getEntityType()->getKey('bundle');
}
/**
* call entity old functions.
*
* @param $name
* @param $arguments
* @return false|mixed
*/
public function __call($name, $arguments)
{
if (method_exists($this->entity, $name)) {
return call_user_func_array(array(
$this->entity,
$name
), $arguments);
}
return false;
}
/**
* call entity old property.
*
* @param $name
* @return FieldItem
*/
public function __get($name) {
return new FieldItem($this->entity, $name);
}
}
/**
* entity field item.
* Class FieldItem
* @package Drupal\dyniva_helper
*/
class FieldItem {
/**
* @var FieldItemListInterface
*/
private FieldItemListInterface $field;
/**
* FieldItem constructor.
* @param EntityInterface $entity
* @param $field
*/
public function __construct(EntityInterface $entity, $field) {
$this->field = $entity->get($field);
}
/**
* set call field old functions.
*
* @param $name
* @param $arguments
* @return false|mixed
*/
public function __call($name, $arguments) {
if (method_exists($this->field, $name)) {
return call_user_func_array(array(
$this->field,
$name
), $arguments);
}
return false;
}
/**
* set call field old property.
*
* @param $name
* @return mixed
*/
public function __get($name) {
return $this->field->{$name};
}
public function emptyValue($default = '') {
if (!$this->field->isEmpty()) {
return $this->field->getString();
}
return $default;
}
/**
* get select field allow values.
*
* @return mixed
*/
public function getAllowValues() {
return $this->field->getSetting('allowed_values');
}
public function selectLabel() {
$allowvalues = $this->getAllowValues();
return $allowvalues[$this->field->value] ?? '';
}
/**
* get ref entity.
*
* @return false|EntityInterface
*/
public function ref() {
if (!$this->field->isEmpty() && $this->field->entity) {
return new Entity($this->field->entity);
}
return false;
}
/**
* get refs entity.
*
* @return false|array
*/
public function refs() {
if (!$this->field->isEmpty()) {
$entitys = $this->field->referencedEntities();
foreach ($entitys as $key => $entity) {
$entitys[$key] = new Entity($entity);
}
return $entitys;
}
return [];
}
/**
* get field targets.
*
* @return array
*/
public function targets() {
if ($this->field->isEmpty()) {
return [];
}
return array_column($this->field->getValue(), 'target_id');
}
/**
* get field values.
*
* @return array
*/
public function values() {
if ($this->field->isEmpty()) {
return [];
}
return array_column($this->field->getValue(), 'value');
}
}
使用方法
$node = node_load(1);
$entity = new \Drupal\mymodule\Entity($node);
$entity->uid->refs(); 获取多个关联entity
$entity->uid->ref(); 获取单个关联的entity
$entity->uid->targets(); 获取多个target_id
$entity->get('titlte')->values(); 获取多个value
$entity->get('select_field')->selectLabel(); 获取list select字段的label. 经常在使用value的时候只会获取Key
关键词：decorates. 比如覆盖系统里logger.factory服务.
以前的调用方式是
\Drupal::logger('my_channel')->notice('hello world');
比如我们想修改日志的写入方式, 定义新的服务
services:
my_log:
parent: logger.factory
decorates: logger.factory
class: Drupal\test_code\Mylog
定义Mylog文件和覆盖getChannel代码. 加一个打印信息
<?php
namespace Drupal\test_code;
use Drupal\Core\Logger\LoggerChannelFactory;
class Mylog extends LoggerChannelFactory{
public function get($channel)
{
dpm('run my loger');
return parent::get($channel); // TODO: Change the autogenerated stub
}
}
