grails - 在Grails和ElasticSearch中解码属性失败

Question

我正在使用Grails 2.5.0和ElasticSearch 0.0.4.6!我有以下域类:

Class Library {
    --- code omitted ---
    static hasMany = [books:Book]
    static searchable = true
    --- code omitted ---
}

Class Book {
    --- code omitted ---
    static belongsTo = [library:Library]
    static searchable = true
    --- code omitted ---
}

我尝试搜索这样的书:

--- code omitted ---
def events = elasticSearchService.search(
            {
                query_string(fields: ["Name"],
                        query: query)
                suggest : { suggest_mode: 'popular' }
            })

    render events as JSON

我收到以下错误:

ERROR unmarshall.DomainClassUnmarshaller - Error unmarshalling property 'library' of Class Book with id 2 Message: Property Book.library is not mapped as [component], but broken search hit found.

Answer 1

您需要将Book域的'library'属性设置为组件。

在您的书域中，替换以下代码

static searchable = true

与

static searchable = { library component: true }
