We have some cases when local context is required for Data fetching, to be able to pass some specific data for child resolvers. In this case, global context from DataFetchingEnvironment is not an option.
An example of using a local context:
return DataFetcherResult.<MobileLandingBlockGraph>newResult()
.data(new BooksMobileLandingBlockGQL(groups.stream()
.map((Function<BooksProductGroup, BooksProductGroupGraph>) BooksProductGroupGQL::new)
.toList()))
.localContext(booksProductService.populateContextForMobile(input.getInput(), "advantures"))
.build();As DataFetcherResult is not supported in the current version of the generator, we have to use the following to be able to generate it for a specific field in GraphQl schema:
abstract class GraphQLCodegenFixesGradleTask : DefaultTask() {
@get:InputFile
abstract val inputFile: RegularFileProperty
@TaskAction
fun updateMobileLandingGridDataGraph() {
val findStr = "java.util.List<MobileLandingBlockGraph>" // Specify the string to find
val replaceStr = "java.util.List<graphql.execution.DataFetcherResult<MobileLandingBlockGraph>>" // Specify the string to replace with
val file = inputFile.get().asFile
val content = file.readText()
val updatedContent = content.replace(findStr, replaceStr)
file.writeText(updatedContent)
}
}
tasks.register<GraphQLCodegenFixesGradleTask>("graphQLCodegenFixes") {
dependsOn("graphqlCodegen")
inputFile.set(file("$buildDir/generated/com/scentbird/web/graphql/model/MobileLandingGridDataGraph.java"))
}Describe the solution you'd like
The solution I'm proposing is the following:
- Add a new property for a plugin:
fieldsWithDataFetcherResult = setOf("@dataFetcherResult")
This property will be used to mark fields that require DataFetcherResult generation. For example:
type MobileLandingGridData {
# blocks of landing grid
blocks: [MobileLandingBlock!]! @dataFetcherResult
# there are more blocks on the next page
hasNext: Boolean!
}
- Update the generator to be able to generate this code.
