我的solr数据导入config.xml看起来像这样
<document>
<entity name="users" pk="id"
query="select id, user_name, site_id from users"
deltaQuery = "select id from users where updated >= '${dataimporter.last_index_time}'"
deltaImportQuery = "select id, user_name, site_id from users where id = ${dataimporter.delta.id}">
<field column="id" name="id"/>
<field column="name" name="user_name"/>
<field column="site_id" name="site_id"/>
<entity name="prefs" pk="id"
query="select pref_value from user_preferences where user_id = '${users.id}'"
deltaQuery="select id from user_preferences where updated >= '${dataimporter.last_index_time}'"
parentDeltaQuery="select user_id as id from user_preferences where id = ${prefs.id}">
<field column="pref_value" name="pref_value" />
</entity>
</entity>
</document>
每个用户可以有多个偏好。现在它只导入它找到的第一个user_preference。如何导入所有用户首选项?
