### Relay Schema
|
||||
|
||||
Graphene also supports Relay, check the (Starwars Relay example)[/tests/starwars_relay]!
|
||||
|
||||
```python
|
||||
import graphene
|
||||
from graphene import relay
|
||||
|
||||
class Ship(relay.Node):
|
||||
'''A ship in the Star Wars saga'''
|
||||
name = graphene.StringField(description='The name of the ship.')
|
||||
|
||||
@classmethod
|
||||
def get_node(cls, id):
|
||||
ship = getShip(id)
|
||||
if ship:
|
||||
return Ship(ship)
|
||||
|
||||
|
||||
class Faction(relay.Node):
|
||||
'''A faction in the Star Wars saga'''
|
||||
name = graphene.StringField(description='The name of the faction.')
|
||||
ships = relay.ConnectionField(Ship, description='The ships used by the faction.')
|
||||
|
||||
@resolve_only_args
|
||||
def resolve_ships(self, **kwargs):
|
||||
return [Ship(getShip(ship)) for ship in self.instance.ships]
|
||||
|
||||
@classmethod
|
||||
def get_node(cls, id):
|
||||
faction = getFaction(id)
|
||||
if faction:
|
||||
return Faction(faction)
|
||||
|
||||
|
||||
class Query(graphene.ObjectType):
|
||||
rebels = graphene.Field(Faction)
|
||||
empire = graphene.Field(Faction)
|
||||
node = relay.NodeField()
|
||||
|
||||
@resolve_only_args
|
||||
def resolve_rebels(self):
|
||||
return Faction(getRebels())
|
||||
|
||||
@resolve_only_args
|
||||
def resolve_empire(self):
|
||||
return Faction(getEmpire())
|
||||
|
||||
|
||||
Schema = graphene.Schema(query=Query)
|
||||
|
||||
# Later on, for querying
|
||||
Schema.execute('''rebels { name }''')
|
||||
|
||||
```
