How to create a Mutation with a List of (something) as argument

[mrbarletta]

Lets say I have a mutation like this

mutation
{createPost(
  title: 'Copa America', 
  description: ' Latest results ',
  authors: [  
     {name: 'Maradona', email: 'maradona@gmail.com' } ,
     {name: 'Messi', email: 'messi@gmail.com' } ]  
)}

How Do I handle this scenario? -

I tried the author ListType( new AuthorType()) ?

ListType is not iterating each AuthorType sent on the request so its failing with Not valid Type....

ResolveValidator line

if (!$argumentType->isValidValue($argumentType->parseValue($argument->getValue()->getValue()))) {

Is receiving the entire array sent and not a single iteration..

I guess we need a InputListType ? or I am missing something

Ok, so the thing here is that your AuthorType should also be an InputType e.g. extended from AbstractInputObjectType. Details in Gitter :)

And example for future references.

$config->getMutation()->addFields([
            'createProperty' => [
                'type' => new PropertyType(),
                'args' => [
                    'title' => new StringType(),
                    'tenants' => new ListType(new InputTenantType()),
                ],
                'resolve' => function($value, $args, $info) {
                    // do your insert
                    return [];
                }
            ]
        ]);
