Graphene: Is it possible to have an array or list as an argument?

[jloveric]

This is a Noob question, is it possible to have a list or array as an argument?

{
  somfunc(value : ["a","b","c"]) {
    value
  }
}

I've tried the above, and if it's possible the syntax is clearly wrong (and the schema). What I really want is a tokenized string as the argument and then process it to eventually return the result. I don't want to do the tokenization in the resolver since it's already been done.

Hi, @jloveric. I do it this way:

class Query(ObjectType):
    some_func = Field(SomeObjectType, args={'value': graphene.List(graphene.String)})

This is real-world example of how to use lists/arrays as input values: Basically the same behavior of the node field, but get a list of Relay nodes for a list of Relay IDs:

import graphene
from graphene import relay

class Query(graphene.ObjectType):
    node = relay.Node.Field(required=True)
    nodes = graphene.List(relay.Node, required=True, ids=graphene.List(graphene.ID))

    def resolve_nodes(self, info, ids=None):
        if ids:
            return [
                relay.Node.get_node_from_global_id(info, node_id)
                for node_id in ids
            ]
        return []

I just did something very similar, but with a list of global IDs

If you need make a filter with multiples choices, you can use GlobalIDMultipleChoiceFilter class..

This filter receive a list of GlobalIds
