我正在尝试使用Grails Criteria来获取Mongodb中hasMany关系的结果，但是没有得到正确的结果。我不确定代码有什么问题，或者我错过了什么。
My Grails版本为3.3.2，mongodb插件版本为6.1.2。
我的域名类是：
SampleDoc.groovy
class SampleDoc implements Serializable{
static mapWith = "mongo"
static belongsTo = [ samplefile : SampleFile ]
static hasMany = [sampleDocElements : SampleDocElement ]
static {
JSON.registerObjectMarshaller(SampleDoc) {
Map properties = it.properties.findAll {it}
properties.put("id", it.id.toString())
return properties
}
}
}
SampleFile.groovy
class SampleFile implements Serializable{
static mapWith = "mongo"
String name
static {
JSON.registerObjectMarshaller(SampleFile) {
Map properties = it.properties.findAll {it}
properties.put("id", it.id.toString())
return properties
}
}
}
SampleDocElement.groovy
class SampleDocElement implements Serializable{
static mapWith = "mongo"
String value
static {
JSON.registerObjectMarshaller(SampleDocElement) {
Map properties = it.properties.findAll {it}
properties.put("id", it.id.toString())
return properties
}
}
}
以下标准不起作用：
SampleDoc.createCriteria().list{
eq ('samplefile', samplefile)
sampleDocElements {
ilike ('value', value)
}
}
我收到错误：
Error :groovy.lang.MissingMethodException:
No signature of method:
org.grails.datastore.mapping.mongo.query.MongoQuery$MongoResultList.call()

(test.SampleDocService$__tt__getSampleDocs_closure45$_closure106)

使用Grails findAllBy不会抛出任何错误，但是为空而不是正确的resultSet：
SampleDoc.findAllBySampleFileAndSampleDocElementsInList(sampleFile, sampleDocElements)
