I've successfully built a GraphQL API which allows nested queries. Using the generic examples of Countries & States, I can perform a query like this:
query{
country(id:"Q291bnRyeTo0Nw==") {
states {
edges {
node {
id,
name,
area,
population
}
}
}
}
}What I've discovered I can't seem to do is this:
query{
country(id:"Q291bnRyeTo0Nw==") {
state(id:"U3RhdGU6MzM=") {
edges {
node {
id,
name,
area,
population
}
}
}
}
}Might there be a way with GraphQL to specify a specific parent and specific child in one query?

Update: For Daniel's benefit, here is my current GraphQL Query code:
from .models import Country as CountryModel
from .models import State as StateModel
class Query(graphene.AbstractType):
country = graphene.Field(Country, id=graphene.String())
countries = graphene.List(Country)
state = graphene.Field(State, id=graphene.String())
states = graphene.List(State)
def resolve_country(self, args, context, info):
id = args.get('id')
if id is not None:
return CountryModel.objects.get(id=Schema.decode(id))
return None
def resolve_countries(self, args, context, info):
return CountryModel.objects.all()
def resolve_state(self, args, context, info):
id = args.get('id')
if id is not None:
return StateModel.objects.get(id=Schema.decode(id))
return None
def resolve_states(self, args, context, info):
return StateModel.objects.all()
