Basic Usage

# models.py
from django.db import models

class Fruit(models.Model):
    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)

# 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.

type Fruit {
  id: ID!
  name: String!
  color: Color
}

type Color {
  id: ID!
  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)),
]

Autocompletion with editors

Some editors like VSCode may not be able to resolve symbols and types without explicit strawberry.django import. Adding following line to code fixes that problem.

import strawberry.django

Running unit tests

poetry install
poetry run pytest
