Store key-less JSON to Realm using Retrofit

Question

I want to save the following JSON from an online API directly to Realm using Retrofit. I am struggling to define the model because there are no keys and the values are dynamic.

JSON:

{
  "Plants": {
    "Green": [
      "Ascia",
      "Musca Arabica"
      ...
    ],
    "Yellow": [
      "Campona",
      "Zirata",
      ...
    ],
    ...
  }
}

Is this even doable? I know I can use a Map<String, Map<String, Set<String>>>, but makeing the Realm model is causing me trouble.

Answer 1

You could flatten it completely.

public class Data extends RealmObject {
    @PrimaryKey 
    private String typeCategoryName; // "Plants_Green_Ascia"

    @Index
    private String type; // "Plants"
    @Index
    private String category; // "Green"

    private String name; // "Ascia"
}

Then you could query it like

RealmResults<Data> data = realm.where(Data.class)
                            .equalTo("type", "Plants")
                            .equalTo("category", "Green")
                            .findAll();
