How to insert RealmList to RealmDB

I am trying to insert realm lists to my realmdb in my first insert there is no problem but when I insert another realmList with a different class, my old values are deleted. So how can I insert a realmlist to DB? inserts are done separately.
RealmList<Product> insertedProduct = new RealmList<Product>();
RealmList<ProductSubCategory> insertedSubCategory = new RealmList<ProductSubCategory>();
RealmList<ProductMainCategory> insertedMainCategory = new RealmList<ProductMainCategory>();
... inserting to realm list firt time ...
insertRealmList(insertedProduct); //inserting to realmDB first time
insertRealmList(insertedSubCategory); //inserting to realmDB first time
insertRealmList(insertedMainCategory); //inserting to realmDB first time
first insert to realmDB
RealmList insert function
private void insertRealmList(final RealmList realmObject) {
mRealm = Realm.getDefaultInstance();
realmTask = mRealm.executeTransactionAsync(
new Realm.Transaction() {
#Override
public void execute(Realm realm) {
realm.copyToRealmOrUpdate(realmObject);
}
},
new Realm.Transaction.OnSuccess() {
#Override
public void onSuccess() {
Log.i(TAG, "onSuccess: successfully inserted data");
}
},
new Realm.Transaction.OnError() {
#Override
public void onError(Throwable error) {
Log.i(TAG, "onError: error while inserting " + "error: " + error);
}
}
);
}
... inserting to realm list second time...
insertRealmList(insertedLanguages); //insert realmDB second time
second insert to realmDB

Other two models are similar with product.

Please try the following method:
private <T extends RealmModel> void insertRealmList(final List<T> objects) {
try (Realm realmInstance = Realm.getDefaultInstance()) {
realmInstance.executeTransaction(realm -> {
for (T object : objects) {
realmInstance.insertOrUpdate(object);

Hope this helps!

Android Nested Objects and Retrofit2

I am reading a JSON like this:
{
"matches": [{
"id": 246119,
"utcDate": "2018-08-17T18:15:00Z",
"status": "FINISHED",
"homeTeam": {
"id": 298,
"name": "Girona FC"
},
"awayTeam": {
"id": 250,
"name": "Real Valladolid CF"
},
"score": {
"winner": "DRAW",
"duration": "REGULAR"
}
}]
}
I must say that the JSON is valid. I am consuming this JSON through an API. I can correctly read the properties "id", "utc" and "status", but I could not with "score", "awayTeam" and "homeTeam". I don't really know how to work those properties. I'd like to handle each propertie of score, awayTeam, and homeTeam individually, for example, I want to get just the name of awayTeam and homeTeam and the 2 properties of score.
This, is my code:
MainActivity
public class MainActivity extends AppCompatActivity {
private Retrofit retrofit;
private static final String TAG = "Football";
private RecyclerView recyclerView;
private ListaPartidosAdapter listaPartidosAdapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
recyclerView = (RecyclerView)findViewById(R.id.recyclerView);
listaPartidosAdapter = new ListaPartidosAdapter(this);
recyclerView.setAdapter(listaPartidosAdapter);
recyclerView.setHasFixedSize(true);
final LinearLayoutManager layoutManager = new LinearLayoutManager(this, VERTICAL, true);
recyclerView.setLayoutManager(layoutManager);
retrofit = new Retrofit.Builder()
.baseUrl("http://api.football-data.org/v2/")
.addConverterFactory(GsonConverterFactory.create())
.build();
obtenerDatos();
}
private void obtenerDatos() {
footballdataService service = retrofit.create(footballdataService.class);
Call<PartidosRespuesta> partidosRespuestaCall = service.obtenerlistaPartidos();
partidosRespuestaCall.enqueue(new Callback<PartidosRespuesta>() {
#Override
public void onResponse(Call<PartidosRespuesta> call, Response<PartidosRespuesta> response) {
if(response.isSuccessful()) {
PartidosRespuesta partidosRespuesta = response.body();
ArrayList<Partido> listaPartidos = partidosRespuesta.getMatches();
listaPartidosAdapter.adicionarListaPartidos(listaPartidos);
}
else {
Log.e(TAG, "onResponse: " + response.errorBody());
}
}
#Override
public void onFailure(Call<PartidosRespuesta> call, Throwable t) {
Log.e(TAG, "onFailure: " + t.getMessage());
}
});
}
}
Now this is my interface. footballdataService
public interface footballdataService {
#GET("competitions/2014/matches")
Call<PartidosRespuesta> obtenerlistaPartidos();
}
This is PartidosRespuestas class
public class PartidosRespuesta {
private ArrayList<Partido> matches;
public ArrayList<Partido> getMatches() {
return matches;
}
public void setMatches(ArrayList<Partido> matches) {
this.matches = matches;
}
}
This, is the adapter.
public class ListaPartidosAdapter extends RecyclerView.Adapter<ListaPartidosAdapter.ViewHolder> {
private static final String TAG = "Football_Adapter";
private ArrayList<Partido> dataset;
private Context context;
public ListaPartidosAdapter(Context context) {
this.context = context;
dataset = new ArrayList<Partido>();
}
#Override
public ListaPartidosAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_partidos, parent, false);
return new ViewHolder(view);
}
#Override
public void onBindViewHolder(ListaPartidosAdapter.ViewHolder holder, int position) {
Partido p = dataset.get(position);
holder.status.setText(p.getId());
}
#Override
public int getItemCount() {
return dataset.size();
}
public void adicionarListaPartidos(ArrayList<Partido> listaPartidos){
dataset.addAll(listaPartidos);
notifyDataSetChanged();
}
public class ViewHolder extends RecyclerView.ViewHolder {
private TextView status;
public ViewHolder(View itemView) {
super(itemView);
status = (TextView) itemView.findViewById(R.id.status);
}
}
}
And this.., is Partido class
public class Partido {
private String id;
private String utcDate;
private String status;
private EquipoCasa homeTeam;
private EquipoVisita AwayTeam;
private Puntaje score;
public String getId() {
return id;
}
public String getUtcDate() {
return utcDate;
}
public String getStatus() {
return status;
}
public EquipoCasa getHomeTeam() {
return homeTeam;
}
public EquipoVisita getAwayTeam() {
return AwayTeam;
}
public Puntaje getScore() {
return score;
}
public void setId(String id) {
this.id = id;
}
public void setUtcDate(String utcDate) {
this.utcDate = utcDate;
}
public void setStatus(String status) {
this.status = status;
}
public void setHomeTeam(EquipoCasa homeTeam) {
this.homeTeam = homeTeam;
}
public void setAwayTeam(EquipoVisita awayTeam) {
AwayTeam = awayTeam;
}
public void setScore(Puntaje score) {
this.score = score;
}
public class EquipoCasa {
private String id;
private String name;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
public class EquipoVisita {
private String id;
private String name;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
public class Puntaje {
private String winner;
private String duration;
public String getWinner() {
return winner;
}
public void setWinner(String winner) {
this.winner = winner;
}
public String getDuration() {
return duration;
}
public void setDuration(String duration) {
this.duration = duration;
}
}
}

POJO classes of your code should this:
AwayTeam.java
//AwayTeam
public class AwayTeam {
#SerializedName("id")
#Expose
private Integer id;
#SerializedName("name")
#Expose
private String name;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
PartidosRespuesta.java
//Object response
public class PartidosRespuesta {
#SerializedName("matches")
#Expose
private List<Match> matches = null;
public List<Match> getMatches() {
return matches;
}
public void setMatches(List<Match> matches) {
this.matches = matches;
}
}
HomeTeam.java
//HomeTeam
public class HomeTeam {
#SerializedName("id")
#Expose
private Integer id;
#SerializedName("name")
#Expose
private String name;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
Score.java
//Score
public class Score {
#SerializedName("winner")
#Expose
private String winner;
#SerializedName("duration")
#Expose
private String duration;
public String getWinner() {
return winner;
}
public void setWinner(String winner) {
this.winner = winner;
}
public String getDuration() {
return duration;
}
public void setDuration(String duration) {
this.duration = duration;
}
}
Edit:
#Override
public void onBindViewHolder(ListaPartidosAdapter.ViewHolder holder, int position) {
Partido p = dataset.get(position);
HomeTeam homeTeam = p.getHomeTeam();
String nameHomeTeam = homeTeam.getName();
}
And tool convert json to java code: http://www.jsonschema2pojo.org/

try
public class Puntaje {
public String winner;
public String duration;
}

It's seems like you've problems with your models. Use this link to convert your json to java object.

Android Json parsing with GSON?

I am quite familiar with Json parsing with Gson. I have done Json parsing using Gson but recently i have multiple json objects with response, i am getting little bit stuck with parsing, here is my code,can anyone help me to solve my problem,that where i am doing wrong.
Thanks in advance
Here is my json response :-

Fetching objects with Collections

I'm trying to list objects that have an inner Collection. I can save and retrieve objects just fine, but when I do:
parentRepo.findAll()
Only the last object has it's child object listed, others has an empty collection.
Parent model
#ForeignCollectionField(eager = false)
private Collection<Child> childs;
Child model
#DatabaseField(foreign=true,foreignAutoRefresh=true)
private Parent parent;
eager true or false doesn't make any difference. If i query a child and get its parent, I can get it's children as well. What am I missing?
Edit:
It's working for the modeling that I made. My mistake was that I need a Many-to-many relation between parent and child. I made a quick research and what I need is an intermediate model to achieve this. I'll close this question and will try to made this many-to-many relation between my models.

I solve my Many-to-Many relationships like this:
This is an example from an ongoing project. I have a Many-to-Many relationship between Preparation and GlideWax. To solve it I use thee classes: Preparation, GlideWax and PreparationGlideWax. PreparationGlideWax represents the connections between the the other classes, just like the way you usually solve many-to-many relationships with a table that is a "link" between the tables in the relationship. As you can see GripWax and Structure also has a Many-to_many relationship to preparation. Here is the code:
GlideWax.java
#DatabaseTable(tableName = "glide_waxes")
public class GlideWax {
#DatabaseField(id = true)
private int id;
#DatabaseField(canBeNull = false)
private String name;
#DatabaseField

As I said in the edit, I'm able to load the child from parent just fine. My problem is that I need a many-to-many relation between my models. I'll accept this answer in two days.

Android Realm return exception "Table has no columns"

This is my code:
PSTrip psTrip = JsonUtil.jsonToObject(jsonObject.toString(), PSTrip.class);
int size = psTrip.getTripSteps().size()-1;
RealmList<Step> steps = psTrip.getTripSteps().get(size).getSteps();
RealmList<TripStep> tripSteps = psTrip.getTripSteps();
Log.i("","continue init after getting tripsteps and steps");
if(tripSteps.size() > 0) {
Log.i("","continue init blabla");
for (int i = 0; i < tripSteps.size(); i++) {
RealmList<Step> mergedSteps = Utils.getMergedSteps(context, tripSteps.get(i).getRoute().getSteps());
tripSteps.get(i).getRoute().getSteps().clear();
for (Step step : mergedSteps) {
tripSteps.get(i).getRoute().getSteps().add(step);
}
}
Log.i("", "continue init after for in which I merge the steps for the tripsteps");
steps = Utils.getMergedSteps(context, steps);
Log.i("", "continue init after merging the steps");
tripSteps.get(size).setSteps(steps);
Log.i("", "continue init after settting steps on tripsteps");
psTrip.setTripSteps(tripSteps);
}
PSTripDBFactory.getInstance(context).addToList(psTrip);
The Utils.getMergedSteps just takes the list of steps (Step from Google maps class), and if it is possible, it merges them.
My problem is at the last line which does:
public void addToList(PSTrip psTrip){
try{
PSTrip insideAlready = getListOfCompletedTripsByID(psTrip.getId());
Log.i("","continue init inside already:" + insideAlready);
if(insideAlready == null){
Log.i("","continue init will copy to realm");
realm.beginTransaction();
realm.copyToRealm(psTrip);
realm.commitTransaction();
Log.i("","continue init will copy to realm finished");
}else{
Log.i("","continue init will copyorupdate to realm");
realm.beginTransaction();
realm.copyToRealmOrUpdate(psTrip);
realm.commitTransaction();
Log.i("","continue init will copyorupdate to realm finished");
}
}catch (Exception e){
Log.i("","continue init error trying to add to realm" + e.getMessage());
realm.cancelTransaction();
}
}
Where getListOfCompletedTripsByID is the following function:
public PSTrip getListOfCompletedTripsByID( String id){
RealmResults<PSTrip> completed = realm.where(PSTrip.class).equalTo("id" , id).findAll();
if(completed.size() > 0){
return completed.get(0);
}else{
return null;
}
}
I get back the following error response:
03-18 11:14:56.135 21908-21908/nl.hgrams.passenger I/﹕ continue init after for in which I merge the steps for the tripsteps

Does anyone have an ideea why does realm return me a "table has no columns" error?
