【问题描述】:
我想在每次更新时将一个对象添加到nested 字段中。
例如,我有一个文档:
{
"test":[{"remark":"remark1"}]
}
下一次,我想在测试字段中添加一个remark 对象并保存旧的remark 对象。结果是:
{
"test":[{"remark":"remark1"},{"remark":"remark2"}]
}
如何实现?
编辑 我使用脚本:
{
"script": "ctx._source.test= ((ctx._source.test?: []) += remarkItem)",
"params": {
"remarkItem": {
"remark": "addd"
}
}
}
但是,我得到了例外:
{
"error": {
"root_cause": [
{
"type": "remote_transport_exception",
"reason": "[es77][10.14.84.77:9300][indices:data/write/update[s]]"
}
],
"type": "illegal_argument_exception",
"reason": "failed to execute script",
"caused_by": {
"type": "script_exception",
"reason": "Failed to compile inline script [ctx._source.test= ((ctx._source.test?: []) += remarkItem)] using lang [groovy]",
"caused_by": {
"type": "script_exception",
"reason": "failed to compile groovy script",
"caused_by": {
"type": "multiple_compilation_errors_exception",
"reason": "startup failed:\na8220b2cf14b8b7ebeead7f068416882d04fa25d: 1: \nclass org.codehaus.groovy.ast.expr.ElvisOperatorExpression, with its value '(ctx._source.test) ? ctx._source.test: []', is a bad expression as the left hand side of an assignment operator at line: 1 column: 82. File: a8220b2cf14b8b7ebeead7f068416882d04fa25d @ line 1, column 82.\n CILastCallResultRemark ?: []) += remarkI\n ^\n\n1 error\n"
}
}
}
},
"status": 400
}
编辑
现在,我想添加一个字段以确保更新或插入对象。 例如:
{
"test":[{"remark":"remark1","id":"1"}]
}
当我更新字段时,当id存在时,我会更新对象。相反,我会插入对象。
【问题讨论】:
-
@Val { "script": "ctx._source.test= ((ctx._source.test?: []) += remarkItem)", "params": { "remarkItem": { "remark": "addd" } } }..这个脚本有错误。为什么?
