I'm struggling to filter on a third level nested object within my JPA repository query.
I have the following object, in which I want to receive all the proms which are part of the journey with id = 5 AND only the promMeasurement objects from the user with id = 12.
proms: [
{
id: 1,
name: "test",
journeys: [
{
id: 5
},
{
id: 6
},
]
promMeasurements: [
{
id: 101,
value: 6,
user: {
id: 12
}
},
{
id: 102,
value: 2,
user: {
id: 13
}
},
{
id: 103,
value: 8,
user: {
id: 14
}
},
]
},
{
id: 2,
name: "test 2",
journeys: [
{
id: 5
},
{
id: 6
},
]
promMeasurements: [
{
id: 223,
value: 1,
user: {
id: 12
}
},
{
id: 224,
value: 5,
user: {
id: 13
}
},
{
id: 225,
value: 3,
user: {
id: 14
}
},
]
},
{
id: 3,
name: "test 3",
journeys: [
{
id: 7
}
]
promMeasurements: [
{
id: 223,
value: 1,
user: {
id: 26
}
},
{
id: 224,
value: 5,
user: {
id: 33
}
},
{
id: 225,
value: 3,
user: {
id: 4
}
},
]
}
]
So the outcome of this all would be to have the following object in the end:
proms: [
{
id: 1,
name: "test",
journeys: [
{
id: 5
}
]
promMeasurements: [
{
id: 101,
value: 6,
user: {
id: 12
}
}
]
},
{
id: 2,
name: "test 2",
journeys: [
{
id: 5
}
]
promMeasurements: [
{
id: 223,
value: 1,
user: {
id: 12
}
}
]
}
]
Right now, I'm already able to do the filtering part on journeys by using this query:
List<Prom> findAllByJourneysId(Long id);
But filtering the promMeasurements didn't yet succeed. A few examples of things I've tried. But those don't work as they just return the same result as the query above.
List<Prom> findAllByJourneysIdAndPromMeasurements_Patient_Id(Long journeyId, Long patientId);
List<Prom> findAllByJourneysIdAndPromMeasurementsPatientId(Long journeyId, Long patientId);
Query log of the last function:
[DEBUG] 2020-08-06 10:57:56.028 [qtp1976725830-44] SQL - select prom0_.id as id1_38_, prom0_.createdAt as createdA2_38_, prom0_.updatedAt as updatedA3_38_, prom0_.name as name4_38_, prom0_.threshold as threshol5_38_ from prom prom0_ left outer join prom_journey journeys1_ on prom0_.id=journeys1_.prom_id left outer join journey journey2_ on journeys1_.journey_id=journey2_.id left outer join prommeasurement prommeasur3_ on prom0_.id=prommeasur3_.prom_id left outer join user user4_ on prommeasur3_.patient_id=user4_.id left outer join user_address user4_1_ on user4_.id=user4_1_.user_id where journey2_.id=? and user4_.id=?
When I manually execute this function, I get the following result. As you can see, each 'prom' is shown two times, which is already not correct.
Someone that can help me with this?
