Hello people, I got a Json like ```[ { // MovieRating.kt "rating": 7 "movie": { // Movie....

# serialization

Hello people,
I got a Json like

[
  { // MovieRating.kt
    "rating": 7
    "movie": { // Movie.kt
      "title": ...,
      ...
  },
  { // ShowRating.kt
    "rating": 8
    "show": { // Show.kt
      "title": ...,
      ...
  }
]

For Movie and Show I've set the discriminator as:

@SerialName("movie")
data class Movie(...): Parent

Now, how to properly set a discriminator for MovieRating and ShowRating, based on the inner field "movie" / "show"?

[ephemient]

it will be easier to deserialize to a

@Serializable
data class RatingContainer(
    val rating: Int,
    movie: MovieRating? = null,
    show: ShowRating? = null,
)

and then map that to the structure you want, possibly wrapped up with https://github.com/Kotlin/kotlinx.serialization/blob/master/docs/serializers.md#composite-serializer-via-surrogate

Thank you for your answer!
I would be glad if I could achieve that without a middle class, as I already have many classes for Trakt API and it’s getting confusing 😄
I will take a look at that doc.
Have you got any alternatives? I rather create a custom serializer, than another data structure 🙂

I took some time to understand the doc: so, basically, the container you mentioned will be used only by the serializer and it will not be part of my model's hierarchy. That sounds amazing! I will give it a try tomorrow.
Thank you again.

Awesome 🍻
