Is it possible to pass an array of inputs to a relay.clientIDMutation?

[samarthkathal]

I want to update a django model that has a one to many relation with the model that has the mutation. I know this is possible with queries and also with graphene.Mutation mutations using class Arguments.

i am currently using graphene.relay.ClientIDMutation and I would like to know if its possible to have a dynamic sized class of inputs as an argument for the mutation.

here is a representation of inputs(array) I want to work with,

mutation{
  addGamePrequels(input:{
    gameThatNeedsPrequels: "game2"
    gamearray:[
      {
        name:"test1",
    	price:"1",
    	datereleased:"2020-07-17",
      },
      {
        name:"test2",
    	price:"1",
    	datereleased:"2020-07-17",
      },
      {
        name:"test3",
    	price:"1",
    	datereleased:"2020-07-17",
      },
    ]
  }
 
  ){
    game{
      name
      collection{
        collectionname
      }
    }
  }
}

@samarthkathal it should be possible to define an input type of List(MyInputType) to a mutation. Does that not work?

Hello, @samarthkathal , @jkimbo

I'm having an issue with the described method of using an input type of List(MyInputType).

Roughly, my code looks like this:

class MyInputType(graphene.ObjectType):
    id = graphene.String(required=True)
    credentials = graphene.JSONString(required=True)


class MyMutation(graphene.Mutation):
    class Arguments:
        my_types = graphene.List(MyInputType, required=True)

    async def mutate(root, info, my_types):
        # Do some stuff

It fails resolving the mutation fields:

  File "/Users/icebreaker/Projects/graphene-test/lib/python3.9/site-packages/graphql/type/definition.py", line 745, in fields
    raise TypeError(f"{self.name} fields cannot be resolved. {error}")
TypeError: MutationRoot fields cannot be resolved. Argument type must be a GraphQL input type.

Moreover, changing the graphene.List to graphene.Argument, raises the same exception.

I have tried to replace the MyInputType with a built-in graphene type: my_types = graphene.List(graphene.String, required=True), and the error did not appear.

I assume it's an issue with supporting custom ObjectType classes in mutation arguments.

@samarthkathal , @jkimbo , Just figured it out.
Custom input types should inherit from graphene.InputObjectType instead of graphene.ObjectType.
Changed to MyInputType(graphene.InputObjectType and it worked like a charm
