Basic Usage

# models.py
from django.db import models

class Fruit(models.Model):
    """A tasty treat"""
    name = models.CharField(max_length=20)
    color = models.ForeignKey('Color', blank=True, null=True,
            related_name='fruits', on_delete=models.CASCADE)

class Color(models.Model):
    name = models.CharField(
        max_length=20,
        help_text="field description",
    )

# types.py
import strawberry
from strawberry import auto
from typing import List
from . import models

@strawberry.django.type(models.Fruit)
class Fruit:
    id: auto
    name: auto
    color: 'Color'

@strawberry.django.type(models.Color)
class Color:
    id: auto
    name: auto
    fruits: List[Fruit]

# schema.py
import strawberry
from typing import List
from .types import Fruit

@strawberry.type
class Query:
    fruits: List[Fruit] = strawberry.django.field()

schema = strawberry.Schema(query=Query)

Code above generates following schema.

"""
A tasty treat
"""
type Fruit {
  id: ID!
  name: String!
  color: Color
}

type Color {
  id: ID!
  """
  field description
  """
  name: String!
  fruits: [Fruit!]
}

type Query {
  fruits: [Fruit!]!
}

# urls.py
from django.urls import include, path
from strawberry.django.views import AsyncGraphQLView
from .schema import schema

urlpatterns = [
    path('graphql', AsyncGraphQLView.as_view(schema=schema)),
]
