On every request (most notably for Flowable) the results are mapped using copyFromRealm

   result.asFlowable()
            .filter { it.isLoaded }
            .map { **realm.copyFromRealm(it)** }
            .subscribe({
                subscriber.onNext(it)
            }, { subscriber.onError(it) })

This is certainly not desirable in every case and would be ideal to have the option to have a locally copied version of the objects or the managed realm backed version.

Consider the following example :

class Parent : RealmObject() {
var id:String?=null
var children:RealmList?=RealmList<>()
}

class Child:RealmObject() {
var id:String?=null
}

If I use a function like queryAllAsFlowable() on the Parent.class and want to display the attribute "children" backed by changes in the DB as a Flowable<RealmList> then this is not possible easily as it could be if the objects emitted were back by realm. If the objects emitted by the functions in RealmExtensionsFlowable were backed by Realm then I could simply do parent.children.asFlowable().

I could of course change the data model to make this work with the current lib, but it would be a shame.

Thank you for the lib in advance and hope I was clear?

I think pushing for RxJava in the library is too much, making it not dependent on it and adding on extension for RxJava 1 and separate extension RxJava2 would be better
I already had issue where I needed to add because of dual versioning of RxJava usage
packagingOptions { // because- com.github.vicpinm:krealmextensions exclude 'META-INF/rxjava.properties' }

Currently to query, I have to write something like this
val events = Event().query { query -> query.equalTo("id",1) }

Which according to me

• Not memory efficient: Because I need to initialize one empty object just to query.
• Not idiomatic: There is a better way to write this query functions.

I think the better way of writing query functions should be something like this

val events = query<Event> {query -> query.equalTo("id", 1) }

This feels more idiomatic and looks memory friendly.

can we get RealmResults instead of returning List when using Event().queryAll()
Thanks for this awesome library

Hello,

I use the RealmAdapter and i need to have an OrderedRealmCollection to pass.

Is it possible with the library ?

Thank's

I have the following crash which slashdot and google do not have any information on...

Process: com.agersens.eshepardcollarfitter.production, PID: 9241
java.lang.IllegalAccessError: Method 'io.realm.RealmQuery io.realm.RealmQuery.createQuery(io.realm.Realm, java.lang.Class)' is inaccessible to class 'com.vicpin.krealmextensions.RealmExtensionsKt' (declaration of 'com.vicpin.krealmextensions.RealmExtensionsKt' appears in /data/app/com.agersens.eshepardcollarfitter.production-1/split_lib_dependencies_apk.apk)

at com.maiatehcology.maialibrary.syncframework.database.DatabaseWrapper.fetchAnimals(DatabaseWrapper.kt:78)

Any hints as to why this might be happening... I used Kotlin realm extensions in another app and it worked and I can't figure out what I did different other than creating two modules, one for the app and one for all the network and realm code...

Will below code work ?

val answerInfo = AnswerInfo().query {
                equalTo("test_id", testId)
                equalTo("saved", false)
            }

Maybe I'm crazy but I can't figure out how to use your library and migrate the schema when I add a new Realm class. All of your code appears to pull the default instance?
The only thing I can see is the sample:

        RealmConfigStore.init(User::class.java, userAddressConfig)
        RealmConfigStore.init(Address::class.java, userAddressConfig)

Does that mean if I use migrations I need to init for every class? But you only use a single config (userAddressConfig) which makes it confusing.

I am using your extension, but I noticed that I want to do a AND query like this:
RealmResults<Person> r1 = realm.where(Person.class) .equalTo("dogs.name", "Fluffy") .equalTo("dogs.color", "Brown") .findAll();

do you have a method to do this? or with the methods that are in your README, Can I do this?
I'll be grateful with your answer, thank you

Hi, I need a little help with realm migration For Kotlin. I know in Java after creating a migration class that extends from io.realm.ReamMigration, you can use the class asrealmConfiguration = RealmConfiguration.Builder() .schemaVersion(REALM_SCHEMA_VERSION) .migration(**new RealmMigration()**) .build()
How can I do same in Kotlin, new RealmMigration() isn't working for me

This library is amazing!, I just have a concern, actually I replaced my old realm storage layer by Realm Extensions, that it's great, but I just discovered you don't have any realm extensions unit testing.

I just would like if you have any example or something like that cuz seems Mockito is not supporting yours extensions :/

Hi @ravidsrk

I'm trying to work with queries and this is what I get at every attempt:

Here's my class declaration.

Thank you in advance!

When trying to make a query that is not for a string, marks

Error:(128, 36) Overload resolution ambiguity:
public open fun equalTo(p0: String!, @Nullable p1: Byte?): RealmQuery<Notification!>! defined in io.realm.RealmQuery
public open fun equalTo(p0: String!, @Nullable p1: Int?): RealmQuery<Notification!>! defined in io.realm.RealmQuery
public open fun equalTo(p0: String!, @Nullable p1: Long?): RealmQuery<Notification!>! defined in io.realm.RealmQuery
public open fun equalTo(p0: String!, @Nullable p1: Short?): RealmQuery<Notification!>! defined in io.realm.RealmQuery

This is the query

Notification().queryAsObservable{
    query -> query.equalTo("status", 0)
}.subscribe { result ->
    //Do something
}

I think right now the extensions are limited to single RealmConfiguration (default).

Maybe we can introduce a extension method that would wrap into additional configurations, like:
User("testuser").realm(realmConfig).save() or User("testuser").save(realmConfig)

Or even remember configuration per Module/RealmObject or set it via initialization.

I get several manifest file merge errors when trying to import the lib
Would it be possible to remove

android:allowBackup="true" 
android:label="@string/app_name"
android:supportsRtl="true"

Are these actually needed, hence it's a library.

Hi! Thank you for the lib!
I'm having the following problem when I try to access my Realm Object:
java.lang.IllegalAccessError: Method 'io.realm.RealmQuery io.realm.RealmQuery.createQuery(io.realm.Realm, java.lang.Class)' is inaccessible to class 'com.vicpin.krealmextensions.RealmExtensionsKt' (declaration of 'com.vicpin.krealmextensions.RealmExtensionsKt' appears in /data/app/ch.farmy.myApp-8cgk5W4ugikhcBaGovMlRw==/base.apk)

Am I missing something? thanks :)

CartModel().queryFirst { it.equalsTo("_ID", 1) }
Method threw 'java.lang.ClassNotFoundException' exception.

this is my class
open class CartModel(
@PrimaryKey open var _ID: Int = 0,
open var qty: Int = 0,
open var foodTitle: String = "",
open var foodDes: String = "",
open var price: String = "",
open var previewURL: String = ""
) : RealmObject() {
fun copy(
_ID: Int = this._ID,
qty: Int = this.qty,
foodTitle: String = this.foodTitle,
foodDes: String = this.foodDes,
price: String = this.price,
previewURL: String = this.previewURL
) = CartModel(_ID, qty, foodTitle, foodDes, price, previewURL)
}

Current solution only supports RealmObject for definition of configuration.
We need to support also second way of creating Realm objects -> @RealmClass and RealmModel interface and RealmModule

I`ve updated kotlin from 1.3.11 to 1.3.20 and after that save() method not working. Just stuck on it. Tested with all combinations of realm\extensions versions. Please check and update libs to work with 5.9 realm and 1.3.20 kotlin. Thanks

Why queries return only detached objects? Isn't Realm so great because of data attached to it's reference?

Great work btw. 👍

Hi, I'm Using realm object server, but I want to know how it is used with sync, because in the README isn't anything about how to use it, Hope your answer, and thank you for your help.

Do I have to always pass an object from Java to access the kotlin extenion like below?

final ChatConversationsRealm F = new ChatConversationsRealm();
List<ChatConversationsRealm> xx = RealmExtensionsKt.queryAll(F);

Is there any way to access it without creating an object but just by specifying the type like RealmExtensionsKt.queryAll(ChatConversationsRealm.class)?

I get this error every time I try to save a record. Please help. This is the code I'm running.

Item("User").save()

I tried to use this library for my project. When I queried realm db via this library it returns "copyFromRealm" value. This will hardly affects the query performance.

Is there any way to get live Realm object with Realm instances management facility?

Thanks for this library. Let's rock realm world.

is their any extension for this, or i need to get all and edit one by one and saving all together ?

Nice tools,

Is there a way to achieve the same observables extensions with live data ?

Hello , Thanks for your great library

why you don't support async transactions in Save , Delete and Update Operations ?

Upon lowering the version to Realm 5.7.0 the code works fine but when I update the version to 5.8.0, and try to save a realm object, it gives me the following exception

I defined an base interface for my repo like this.

interface BaseDataStore<T : RealmObject> {

    fun getObject(): T
    fun getPrimaryKeyAttribute(): String
    fun getPrimaryKey(item: T): String

    fun add(item: T): Completable {
        return Completable
                .fromAction { item.save() }
}

It was compiling with 1.x version, but I just updated with latest version of realm extension + realm 3.5 => real 4.1 an this is not compiling anymore:

I get: cannot use t as reified type parameter use class instead

H Antonio, this library is awesome!
Although I've noticed that the proguard rules are missing in the Readme.md, could you add them? I'm having problems building when minify is enabled.

Adding
compile "com.github.vicpinm:krealmextensions:1.1.5"
to build.gradle and then I get below error:

I'm using Realm Extensions but currently no all our code is on Kotlin we have several layers that will need to refactor (Java), I know extensions are not supported on java, that why I created like and Grapper on kotlin that recieve RealmQuery instead of Query

I'd like to know (if you know). How I can made the compatibility between Query injected from a java class as RealmQuery.

I'm already know that you defined as

public typealias Query<T>  = io.realm.RealmQuery<T>.() -> kotlin.Unit

Where I supposed if you inject a field as RealmQuery should be supported, but seems like you library ignore my RealmQuery injected cuz isn't a Query

There's my example wrapper created in Kotlin it receive a class, fieldName, order and _query

    override fun <T : RealmObject> querySortedObjects(_clazz: Class<T>, _fieldName: String, _order: Sort, _query: RealmQuery<T>): List<T> {
        val newInstance = _clazz.newInstance()
        val results = newInstance.querySorted(_fieldName, _order, {
            _query
        })

        Timber.d("$javaClass -> querySortedObjects: ${_clazz.javaClass} results: ${results.size}")

        return results
    }

   override  fun <T : RealmObject> queryByClass(_clazz: Class<T>): RealmQuery<T>? {
        return try {
            Realm.getDefaultInstance().where(_clazz)
        }catch (e : Exception){
            null
        }
    }

And there's my code provide from java.

    @Override
    public List<User> getFavorites(@NotNull String query) {

        RealmQuery<User> userRealmQuery = mRealmProvider.queryByClass(User.class);

        if (userRealmQuery != null){

            userRealmQuery.equalTo("favorite", true);

            if (query.length() > 0)
                userRealmQuery.and().contains("name", query, Case.INSENSITIVE);

            userRealmQuery.isNotNull("name");

            return mRealmProvider.querySortedObjects(User.class, "name", Sort.ASCENDING, userRealmQuery);
        }
        return new ArrayList<>();
    }

Seems ignore my RealmQuery param

Then seems just perform this

val results = newInstance.querySorted(_fieldName, _order)

Hi,
so this is my class:

@AutoIncrementPK
open class Contact() : RealmObject() {
    @PrimaryKey
    var id: Long? = null
    var name: String = ""
    var publicKey: String = ""

    constructor(name: String, publicKey: String) : this() {
        this.name = name
        this.publicKey = publicKey
    }
}

I tried to do an update on an object like this:

contact.name = name
contact.save()

And instead of updating the object, a new object with these properties and new id is created. I checked the code and obviously the line initPk in save overrides the primary. I don't think that this is intended to happen, is it?

Hello,

I would to query my object and have in result an ObservableList. I need this to use the lib with the lib LastAdapter, is it possible ?

Thank's

Hi. library version 2.4.0, Realm version 5.8.0. I try to get one element by id, but have error!

1. This is DB call:
   fun getDataById(id: Int): Flowable {
   return RealmCar().queryAsFlowable {equalToValue("id", id)}
   }
2. This is error: http://joxi.ru/D2P9y6QHpnbjpA

Hello,

When queryAsFlowable, if I add Consumer for subscription in subscribe, the flowable doesn't work at all. I have to handle the subscription in doOnSubscribe in order to work. Is this normal behavior or a bug?

is there a queryAllManagedInstance(realmInstance)? or something equivalent?

Hey there, is there any plan to migrate to RxJava2 for your library? Currently, I'm getting conflicts during compilation when using RxJava2 and Kotlin-Realm-Extensions.

Thank you

I am building a fairly large application using this library. We've noticed on older devices that performance is poor. We identified the problem to be that the RealmExtensionsFlowable file creates a new thread and looper for every subscription if it's not already on the main thread. This causes a large number of threads with loopers, all contending for limited resources. To better understand scope -- we're using Nexus 5 and Nexus 6P as poor performing devices with 10s-20s lockups. Pixel 2 you don't really notice anything.

As a short-term solution, I forked the repo and replaced the thread creation with a singleton thread with a looper. All the performance issues go away. You can see the commit here bricestacey@e07ebab

I'm curious what we might be able to do to allow this behavior to be configurable. Off the top of my head

1. Add a parameter to the flowable extensions to specify a scheduler
2. Refactored to use some default LooperFactory, then expose a means of configuring it

I kind of think both are desirable. 1 is sufficient, but 2 would allow setting a default case or more complex strategies. I have only been using Kotlin a few months and this is the only extension library I'm using outside the core android one. I haven't seen anything yet for how to configure them so don't have much insight.

Happy to take a stab at this, but wanted to bring it up before I started down some haphazard path.

What do you think about adding support for RealmModel interface?

I'm not 100% sure if this would be important to other users, because even if you only implement RealmModel and add RealmClass annotation you still cannot extend from different classes then RealmObject. But still there may be some users that prefer this approach.

If you think this would be a nice to have feature I can prepare a PR to discuss :)

RealmQuery.createQuery in Realm 4.0 seems to be protected:

This library is really handy.

Is there a way to delete all from a managed instance? kind of like when you call .saveAllManaged()
so I can delete only from the managed instance?

Hi,
your library seems very interesting, I have been thinking about making the migration definitions more readable. Right now, I see as the best option to provide inline functions so you can write them like Anko does for layouts. What do you think? Once we agree on a way to add it, I will send a PR

Example:

val migration = realmMigration {
    migrate(fromVersion = 1) {
        newModel<MyModel>() {
            field<String>(name = "id") {
                primaryKey = true
            }
            field<Int>(name = "number")
        }
    }
    
    ...
}

Hello,
I can't make your extension work, I've got this error when I build :

Execution failed for task ':app:transformNativeLibsWithMergeJniLibsForDebug'.

More than one file was found with OS independent path 'lib/x86/librealm-jni.so'

I tried to clean, rebuild but it still doesn't work.
It looks like a conflict but I really have no idea of how to solve it.
I tried with an all new empty project too (I just included all the libraries I use in my main project)

Edit : I just saw this issue an it does solve the problem but according to realm documentation :

Enabling Realm Mobile Platform: Before your application can synchronize with the Realm Object Server, it has to be enabled in your build file. Add this to the application’s build.gradle:
realm {
syncEnabled = true;
}

So this line is necessary to make object server work. So, can your extensions work with it?

This is my project gradle file :

// Top-level build file where you can add configuration options common to all sub-
projects/modules.

i want to get the parent of specific object i have implemented this code

open class Parent() : RealmObject(){
  var steps: RealmList<Child>? =RealmList()}

and in Child

@LinkingObjects("steps")
    val parent: RealmResults<Parent>? = null

when i do this query StepDataStore.getObject().query { equalTo("parent.id", id, Case.INSENSITIVE) } }
i get always null

May you explain difference between createOrUpdate() and save() methods? Are they equal?

Hi,
how can I convert MutableList to RealmList?

Hello,
I would like avoid the filter{} like my sample
val documentsNotGetCount = RDocument().query { equalToValue("mission.id", mission?.id!! ) }.filter { rDocument -> !rDocument.is_get }.count()

Is it possible ?

Than,k's
