Hi all,

Does anyone have any advice regarding support for DataFetcherResult<List<DataFetcherResult<Entity>>> style return types as per this issue? https://github.com/ExpediaGroup/graphql-kotlin/issues/1337

I am happy to try and get a PR to add support for this; but before doing so, I wanted to make sure this requirement makes sense and get any advice on how to implement this feature?

somewhat curious on the use case here -> if you already have computed the result why do you need to update the local context?

[Daniel Ryan]

Sure, this is not really explained by the simple example provided, but it is for what I believe is a typical use case for localStorage. It is for the case whereby entity allows listing sub-entities, and these sub-entities might have sub-sub-entities. Each level needs to understand the context of the previous levels to be able to filter effectively (for example region->sales->items).

I am not experienced with GraphQL, but I believe it is this kind of use-case that localStorage was created for?

[Dariusz Kuc]

gotcha yeah if entity have some child fields that would be function calls then yeah I guess you would use local context

[Daniel Ryan]

Created a PR. I would be very gratefully if someone can review? As well as testing that the schema generation works, I also tested on my application to make sure it works with the GraphQL Java libraries and it does 🙂
