[英]ElasticSearch.Net - Update array with multiple components
I've got data indexed using ElasticSearch, and I'm having trouble updating a particular field. 我已经使用ElasticSearch索引了数据,但在更新特定字段时遇到了麻烦。 A snippet of the JSON is as follows:
JSON的片段如下:
{
"_index": "indexName",
"_type": "type",
"_id": "00001",
"colors": [
"red",
"green"
]
"place": "london",
"person": [
{
"name": "john",
"age": "27",
"eyes": "blue"
}
{
"name": "mary",
"age": "19",
"eyes": "green"
}
]
}
I need to add in a new person
object, something like: 我需要添加一个新的
person
对象,例如:
{
"name": "jane",
"age": "30",
"eyes": "grey"
}
I've got People
defined as follows: 我已经将
People
定义如下:
public class People
{
public List<string> colors {get; set; }
public string place {get; set; }
public List<Person> person {get; set; }
}
public class Person
{
public string name {get; set; }
public string age {get; set; }
public string eyes {get; set; }
}
I updated color
with no problems by doing: 通过执行以下操作,我更新
color
没有问题:
client.Update<People>(u => u
.Id(u.Id)
.Index(u.Index)
.Type(u.Type)
.Script("if ctx._source.containsKey(\"color\")) { ctx._source.color += color; } else { ctx._source.color = [color] }")
.Params(p => p
.Add("color", "pink"))
);
I can't figure out how to update the person
field though, as it's a list of Person
objects rather than a list of strings. 我无法弄清楚如何更新
person
字段,因为它是Person
对象列表而不是字符串列表。
Any help is greatly appreciated! 任何帮助是极大的赞赏!
I have done this previously by using an anonymous object and sending a partial document update to Elasticsearch to only update the needed section. 我以前通过使用匿名对象并将部分文档更新发送给Elasticsearch来仅更新所需的部分来完成此操作。
Here is a code snippet that should work... 这是一个应该起作用的代码片段...
var peopleId = //Get Id of document to be updated.
var persons = new List<Person>(3);
persons.Add(new Person { name = "john", eyes = "blue", age = "27" });
persons.Add(new Person { name = "mary", eyes = "green", age = "19" });
persons.Add(new Person { name = "jane", eyes = "grey", age = "30" });
var response = Client.Update<People, object>(u => u
.Id(peopleId)
.Doc(new { person = persons})
.Refresh()
);
