Kotlin-GDE commented 6 years ago

hi good work,

i suggest to add more attributes for collection mapping (exp : orphanRemoval, mappedBy),
there is a bug problem when use bidirection relationship (exp : person -> cars , car -> own person) when persist data there an exception for rerurcive data (spring boot + jackson) because the 2 side off relationship refrences recursivly one to other (person -> list cars & car -> person -> list cars -> ......, son can resole this without loose the the reference of 2 relationship

Hello

Thank you for submitting the issue, don't forget to star the repository if you enjoy!.

Regarding mappedBy, I have been working on it since a few days , in fact due to absence of persistence context and transactional cache it's a little bit difficult to implement it but I think it should be a manner to achieve this may be not like jpa but with a non-full featured version.
Regarding orphanRemoval it is possible to implement it with no problems in theory.

I will give you feedback of the progression on these features.

hi

how about if i referrence a car owner (person) so when persist data (with spring boot) i have n exception of recusisvity between cars and person (person -> list cars -> each car -> person -> list cars -> ....) it possible to not reference a person from car entity but in this case you loose the info about the owner of car from car entity, so how to resole this probleme of recursivity data between bidiection relationships

hi

that's what I said in my comment the only solution is the mappedBy and I'm working on it

Kotlin-GDE commented 6 years ago

hi

i try to resolve this exception with @JsonView @JsonManaged @JsonBackRef but the second side of relationship is broken (exp : car has no ref for owner = person) but this not what i want

hi

I will deliver a release candidate version soon to fix your problem. I will drop a comment here to inform you.

kaiso commented 6 years ago

Hello I delivered the version 2.2.0-RC1 The version introduces the mappedBy property to enable bidirectional associations. To use the OneToOne bidirectional mapping follow the following example:

// in person class
    @OneToOne(fetch=FetchType.EAGER)
    @JoinProperty(name = "passport")
    private Passport passport;

//in passport class 
   @OneToOne(mappedBy = "passport", fetch = FetchType.EAGER)
    private Person owner;

To use the OneToMany bidirectinal mapping follow the following example:

//in person class
    @OneToMany(fetch=FetchType.EAGER, cascade = CascadeType.ALL)
    @JoinProperty(name="carsrefs")
    private List<Car> cars;

//in car class
    @ManyToOne(mappedBy="cars")
    private Person owner;

Please let me know if all works well for you, do not forget to star the repository. Feel free to submit the issues you discover. IMPORTANT! this is only a candidate version, so there are some changes until the final version is released.

Thank you

hi

first i try to make s demo with @OntoMany (Person)-> @ManyToOne (Car) (jdk 11 , kotlin 1.2.60, spring boot 2.0.4 + reactive mongodb driver)

@Document @TypeAlias(value = "car") data class Car(@Id var id: String? = null, var marque: String? = null, @ManyToOne(mappedBy = "cars") var owner: Person? = null) {

override fun equals(other: Any?) = if(other is Car) id == other.id else false

}

@Document @TypeAlias(value = "person") data class Person (@Id var id: String? = null, var name: String? = null, var age: Int? = null, @JsonFormat(pattern = "dd/MM/yyyy", shape = JsonFormat.Shape.STRING) var dateNais: LocalDate? = null, @JsonProperty("cars") @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY) var cars: MutableList? = null) {

override fun equals(other: Any?) = if(other is Person) id == other.id else false

}

@SpringBootApplication @EnableRelationalMongo class DemoApplication(val personRepository: PersonRepository, val carRepository: CarRepository) : ApplicationRunner { override fun run(args: ApplicationArguments?) { val person = Person().apply { id = "person-1" age = 36 name = "halim" this.dateNais = LocalDate.of(1982,3,18) }

    val car = Car().apply {
        owner = person
        id = "car-1"
        marque = "oodi-7"
    }

    person.cars?.add(car)

    personRepository.save(person).log().subscribe()
    //carRepository.save(car).log().subscribe()
}

}

so the car instance its saved with success, person instance not saved (car have no cascade to save person instance) also person collection not created

Hi

The exception is clear if you look at the stack trace : ˋˋˋjava io.github.kaiso.relmongo.exception.RelMongoConfigurationException: Missing or misconfigured @JoinProperty annotation on Field cars from Class class com.spring.mongodb.demo.demo.entity.Person at io.github.kaiso.relmongo.util.AnnotationsUtils.getJoinProperty(AnnotationsUtils.java:45) ~[relmongo-2.2.0-RC1.jar:na]ˋˋˋ

you are missing the @JoinProperty (and not JsonPropery)

good luck

i i use carRepositoty.save(car) -> car persist with owner (person) success but person list cars still empty in person document (no reference for cars)

Hi

you followed exactly what was mentionned in the wiki to do cascading ? normally if you do so, when you persist a person, the cars are persisted automatically by RelMongo. try to follow exactly the usage in the wiki and if you have an issue please open a dedicated issue and close this one because it is not the same issue.

kaiso / relmongo
