Mandatory arguments

[Fredrikp-ume]

Hi,
is it possible to specify that a value has to be provided when querying?

an example:
type Query { dataset(id: Int!): Dataset}

It crashes when I try to build the schema

cheers

Hello Fredrikp-ume, Thank you very much for your comment.

The schema only defines the structure of the data, similar to a database schema

type Person {
  name: String
  age: Int
}
 type Query{
  person: Person
  neomatrix: Persona
}

In the resolvers it is where it is determined what data will be returned from the query with respect to the input data. link to documentation

resolvers=Dict(
    "Query"=>Dict(
        "neomatrix" => (root,args,ctx,info)->(
        	return Dict("name"=>"josue","age"=>25,"height"=>10.5,"spooilers"=>false)
        	)
        ,"person" => (root,args,ctx,info)->(
        	return Dict("name"=>"Diana","age"=>14,"height"=>11.8,"spooilers"=>true)
        	)
    )
)

A resolver function receives four arguments:

1. root :
   The previous object, which for a field on the root Query type is often not used.

2. args :
   The arguments provided to the field in the GraphQL query.

3. context:
   A value which is provided to every resolver and holds important contextual information like the currently logged in user, or access to a database.

4. info:
   A value which holds field-specific information relevant to the current query as well as the schema details.
