我希望能够在ES索引中存储json对象。下面是我试图存储的一个示例(这是一个序列化模型,一个发送给ES的请求体):
"{"id":218,"name":"Test2","category_id":1,"address":"Pushkin street","phone":null,"site":null,"location":{"lat":64,"lon":70},"city":"Heaven","description":"Super company","tags":["#test1","#test2"]}"当我试图存储它时(当然是通过扩展),下面是ES返回的错误:
"{"error":{"root_cause":[{"type":"mapper_parsing_exception","reason":"failed to parse [location]"}],"type":"mapper_parsing_exception","reason":"failed to parse [location]","caused_by":{"type":"illegal_argument_exception","reason":"unknown property [lat]"}},"status":400}"如果没有特定类型的映射(如docs:https://www.elastic.co/guide/en/elasticsearch/reference/1.4/mapping-object-type.html ),我似乎无法做到这一点。
但是,我似乎没有找到在模型中提供映射的方法。扩展的文档并没有真正说明任何关于它的信息。所以,我的问题是:我需要它吗?如果我需要,怎么做?
感谢所有反馈。

我假设您的模型是\yii\elasticsearch\ActiveRecord。您需要描述它的属性:
public function attributes()
{
return [
'name',
'category_id',
'address',
'phone',
'site',
'location',
'city',
'description',
'tags'
];
}不要忘记配置index()和type()。在下面的示例中,type是my_address。
然后,您将需要使用创建索引和适当场映射。下面是您的映射应该是什么样子:
"mappings" : {
"my_address" : {
"properties" : {
"name" : { "type" : "string"},
"category_id" : { "type" : "integer"},
"address" : { "type" : "string"},
"phone" : { "type" : "string"},
"site" : { "type" : "string"},
"location" : { "type" : "geo_point"},
"city" : { "type" : "string"},
"description" : { "type" : "string"},
"tags" : { "type" : "string"}
}
}
}注意三件事:
geo_point类型。string。这也将允许它们成为字符串数组。$model->primaryKey = '123')。否则,您的ES模型将其内部id设置为类似于AVDXmfJ3Ou7LzqD1DDMj的内容,并且还有一个不太方便的id字段。我鼓励您更仔细地查看映射--在配置字符串的准确分析方式时,它们非常重要。
更新:您没有真正描述模型中任何位置的映射的。在迁移中这样做--类似于在SQL中创建表。

如果您使用ElasticSearch ActiveRecord,您可以为setupMapping定义一个方法
Class BookIndex extends yii\elasticsearch\ActiveRecord
{
/**
* sets up the index for this record
*
*/
public static function setUpMapping()
{
$db = static::getDb();
//in case you are not using elasticsearch ActiveRecord so current class extends database ActiveRecord yii/db/activeRecord
// $db = yii\elasticsearch\ActiveRecord::getDb();
$command = $db->createCommand();
/*
* you can delete the current mapping for fresh mapping but this not recommended and can be dangrous.
*/
// $command->deleteMapping(static::index(), static::type());
$command->setMapping(static::index(), static::type(), [
static::type() => [
// "_id" => ["path" => "id", "store" => "yes"],
"properties" => [
'name' => ["type" => "string"],
'author_name' => ["type" => "string"],
'publisher_name' => ["type" => "string"],
'created_at' => ["type" => "long"],
'updated_at' => ["type" => "long"],
'status' => ["type" => "long"],
],
],
]);
}
}稍后,您只需要在任何时候调用此方法,就可以应用新的映射。
