Variables are not supported

[Oxymoron290]

When creating a query like the following, I get a 500 error.

{
    "query":"query($id: Int!)
    {
        TruckLoad(id: $id){
            id
            truckload{id}
        }
    }",
    "variables":{
	"id": 5
    }
}

The endpoint throws an exception about a null argument

com.apurebase.kgraphql.RequestException: argument id is not optional, value cannot be null

However, if I specify a default variable, like the following, the endpoint returns, but only using the default value (2 in this example) instead of the defined variable (5 in this example)

{
    "query":"query($id: Int! = 2)
    {
        TruckLoad(id: $id){
            id
            truckload{id}
        }
    }",
    "variables":{
	"id": 5
    }
}

how are you calling .execute() ?

Passing variables is split into 2 different arguments.

Here's an example:

val dollarSign = '$'

val query = """
    query(${dollarSign}id: Int! = 6){
        TruckLoad(id: ${dollarSign}id) {
            id
            TruckLoad{
                id
            }
        }
    }""".trimIndent()
val variables = """
    {
        "id": 5
    }
""".trimIndent()

val res = schema.execute(query, variables)

println(res)

Using ktor:

routing {
    route("/graphql") {
        post {
            val request = call.receive<GraphQLRequest>()
            val query = request.query
            val context: ThetaContext by inject()
            val sch = ThetaSchema(context)
            val result = sch.schema.execute(query)
            call.respondText(result, io.ktor.http.ContentType.Application.Json)
        }
    }
}

I'm planning to do a module for ktor, so in the feature you would just install KGraphQL into ktor something like this:

embeddedServer(...) {
    install(KGraphQL)
}

But for for you could take a look at this project: https://github.com/jeggy/ktorgraphql/blob/master/src/Application.kt#L55

I think I saw a PR or something about that in ktor's project. do you have a link?

[jeggy]

I've seen some that are using the java implementation of GraphQL. But I haven't seen any for KGraphQL.
I'm gonna do one that is specifically made for KGraphQL

[Oxymoron290]

Awesome. also, trying your solution it shows that request does not have properties for mutation or variables

Using v0.6.6

I'm sorry, I got confused
