我已经尝试设置迁移模块一段时间了，但没有成功地将分类术语与节点关联起来。
让我们首先说，它的不是D2D迁移，源是旧的symfony数据库！
首先，我成功地导出了分类术语：
*.migrate.inc:
...
'symfony_db_countries' => array(
'class_name' => 'MigrateSymfonyCountriesMigration',
'group_name' => 'symfony_db_loc',
),
'symfony_db_cities' => array(
'class_name' => 'MigrateSymfonyCitiesMigration',
'group_name' => 'symfony_db_loc',
'dependencies' => array('symfony_db_countries'),
),
'symfony_db_sights' => array(
'class_name' => 'MigrateSymfonySightsMigration',
'group_name' => 'symfony_db_loc',
),
...
城市公司：
class MigrateSymfonyCitiesMigration extends MigrateSymfonyCitiesMigrationBase {
const TABLE_NAME = 'ya_loc_city';
public function __construct($arguments = array()) {
parent::__construct($arguments);
$this->description = t('Migrate cities from Symfony DB.');
$query = Database::getConnection('symfony', 'default')->select('ya_loc_city', 'c');
$query->leftJoin('ya_loc_city_translation', 'ct', 'ct.id = c.id');
$query->fields('c', array());
$query->fields('ct', array());
$this->source = new MigrateSourceSQL($query, array(), NULL, array('map_joinable' => FALSE));
$this->destination = new MigrateDestinationTerm('cities');
$this->map = new MigrateSQLMap($this->machineName,
array(
'id' => array(
'type' => 'int',
'not null' => TRUE,
'description' => 'City ID',
),
),
MigrateDestinationTerm::getKeySchema()
);
$this->addFieldMapping('name', 'name');
$this->addFieldMapping('parent', 'country_id')->sourceMigration('symfony_db_countries');
}
}
然后，我从另一个表中创建节点，该表具有分类术语的entityReference字段（field_city）。
<?php
class MigrateSymfonySightsMigration extends Migration {
public function prepareRow($row) {
parent::prepareRow($row);
$row->point = 'point (' . $row->longitude . ' ' . $row->latitude. ')';
}
public function __construct($arguments = array()) {
//entry is the name of a group.
parent::__construct($arguments);
$this->description = 'Migration sights';
/*************SOURCE DATA*************/
...
$this->source = new MigrateSourceSQL($query, array(), NULL,
array('map_joinable' => FALSE));
$this->destination = new MigrateDestinationNode('sight');
/*************MAPPING*************/
$this->addFieldMapping('field_city', 'name')->sourceMigration('symfony_db_cities');
$this->map = new MigrateSQLMap($this->machineName,
array(
'id' => array('type' => 'int',
'unsigned' => TRUE,
'not null' => TRUE,
)
),
MigrateDestinationNode::getKeySchema()
);
}
}
symfony表中有一列"name"，其中包含类似"Paris"的城市名称。
如何将此列（'name'）值（'Paris'）与分类术语相关联？以下不起作用：
$this->addFieldMapping('field_city', 'name')->sourceMigration('symfony_db_cities');
首先，确保您的"field_city"字段接受"cities"术语。
然后确保MigrateSymfonyitiesMigration是MigrateSymonySightsMigration的依赖项。
根据文档，术语引用字段迁移默认情况下具有术语名称的"source_type"。确保"ignore_case"设置正确。
如果所有其他操作都失败，则将MigrateSymfonyitiesMigration映射源id1更改为"name"而不是"id"，然后重试（必须重新注册迁移）：
$this->map = new MigrateSQLMap($this->machineName,
array(
'name' => array(
'type' => 'varchar',
'length' => 255,
'not null' => TRUE,
'description' => 'City Name',
),
),
MigrateDestinationTerm::getKeySchema()
);
