Is there a way to grab the parent argument in a DgsData function?

[BCantos17]

Given a schema like this

type Actor {
    name: String
    movies(size: Int): [Movie]
}

type Movie {
    name: String
}

type Query {
    actor(id: String)
}

and given a movie field implementation. is there a way to grab the id field from the actor query? Maybe something like this?

    @DgsData(parentType = "Actor", field = "movies")
    fun movies(dfe: DgsDataFetchingEnvironment, @InputArgument size: Int): List<Movie> {
        val id = dfe.arguments["id"] as String? ?: ""
        return movieService.getMoviesByActorId(id, size)
    }

Currently arguments only has the the arguments for the query it is being called in and not the parent query

You can pass any additional information as part of the context to child data fetchers, so you could add it there: https://netflix.github.io/dgs/advanced/context-passing/#no-showid-use-local-context

The other alternative for the parent is to inspect the Data fetching environment that's passed in and extract it, a bit more convoluted.

Hope this helps.

Does the first solution work with reactive code? Would I return a Mono with a DataFetcherResult or do I return a DataFetcherResult with a Mono?

Just tested it out, it works with a mono of a DataFetcherResult. Thanks @srinivasankavitha!

👍 . Yes it works the same way with Mono as well.
