amacleay-cohere opened a new issue, #14382:
URL: https://github.com/apache/grails-core/issues/14382
This issue is WIP - I apologize for the lack of detail at this point. I will
be adding to it presently.
I have a simple POGO class that has an embedded property
```groovy
package com.partypeople
import grails.persistence.Entity
import javax.persistence.Embeddable
@Entity
class PersonAttribute {
String id
List<AttributeContext> contexts = []
static embedded = ['contexts']
}
@Embeddable
class AttributeContext {
String id
String neighborhoodId
static belongsTo = [attribute: PersonAttribute]
}
```
I would like to generate a query on an embedded field:
```groovy
package com.partypeople
import grails.gorm.services.Service
import grails.gorm.services.Where
@Service(PersonAttribute)
interface PersonAttributeDataService {
@Where({ contexts { neighborhoodId == neighborhoodId } })
List<PersonAttribute> findByNeighborhoodId(String neighborhoodId)
}
```
```groovy
package com.partypeople
import grails.test.mongodb.MongoSpec
import grails.testing.gorm.DataTest
import grails.testing.services.ServiceUnitTest
class PatientAttributeDataServiceSpec extends MongoSpec implements DataTest,
ServiceUnitTest<PersonAttributeDataService> {
void "Can do"() {
given:
def attribute = new PersonAttribute(contexts: [new
AttributeContext(neighborhoodId: '1234')])
attribute.save()
when:
def res = service.findByNeighborhoodId('1234')
then:
res.size() == 1
res[0].contexts.neighborhoodId == '1234'
}
}
```
Fails with
```
java.lang.NullPointerException
