How to dynamically generate Graphene 2.0 objects mid-runtime

A quick a dirty example of how a dictionary could be used modify Graphene ObjectType field definitions without restarting the engine.

import graphene

modeled = [{
    "type": "String",
    "name": "hello"
}]


class Query(graphene.ObjectType):
    hello = graphene.String(argument=graphene.String(default_value="stranger"))

    def resolve_hello(self, info, argument):
        return 'Hello ' + argument


class Query2(graphene.ObjectType):

    empty = graphene.String()

    def resolve_hello(self, info, argument):
        return 'Hello ' + argument

for m in modeled:
    t = getattr(graphene, m.get('type'))
    n = m.get('name')
    d = graphene.Dynamic(lambda: t)

    f = graphene.Field(
        graphene.String,
        argument=graphene.String(default_value="stranger")
    )

    Query2._meta.fields.update({n: f})
    setattr(Query2, n, t(argument=graphene.String(default_value="stranger")))

schema = graphene.Schema(query=Query)
schema2 = graphene.Schema(query=Query2)

result = schema.execute('{ hello }')
print(result.data['hello']) # "Hello stranger"

# or passing the argument in the query
result = schema2.execute('{ hello (argument: "graph") }')
print(result.data['hello']) # "Hello graph"
