Strawberry GraphQL Django extension
Project description
Strawberry GraphQL Django extension
This library provides helpers to generate fields, mutations and resolvers for Django models.
Sample project files
models.py:
from django.db import models
class User(models.Model):
name = models.CharField(max_length=50)
age = models.IntegerField()
groups = models.ManyToManyField('Group', related_name='users')
class Group(models.Model):
name = models.CharField(max_length=50)
schema.py:
import strawberry
from strawberry_django import ModelResolver, ModelPermissions
from .models import User, Group
class UserResolver(ModelResolver):
model = User
@strawberry.field
def age_in_months(info, root) -> int:
return root.age * 16
class GroupResolver(ModelResolver):
model = Group
fields = ['name', 'users']
# only users who have permissions for group models can access and modify
permissions_classess = [ModelPermissions]
def get_queryset(self):
qs = super().get_queryset()
if not self.request.user.is_superuser:
qs = qs.none()
return qs
@strawberry.type
class Query(UserResolver.query(), GroupResolver.query()):
pass
@strawberry.type
class Mutation(UserResolver.mutation(), GroupResolver.mutation()):
pass
schema = strawberry.Schema(query=Query, mutation=Mutation)
urls.py:
from strawberry.django.views import GraphQLView
from .schema import schema
urlpatterns = [
path('graphql', GraphQLView.as_view(schema=schema)),
]
Add models and schema. Create database. Start development server.
pip install strawberry-graphql-django
manage.py makemigrations
manage.py migrate
manage.py runserver
Mutations and Queries
Open http://localhost:8000/graphql and start testing.
Create new user.
mutation {
createUser(data: {name: "my user", age: 20}) {
id
}
}
Make first queries.
query {
user(id: 1) {
name
age
groups {
name
}
}
users(filters: ["name__contains=my", "!age__gt=60"]) {
id
name
age_in_months
}
}
Update user data.
mutation {
updateUsers(data: {name: "new name"}, filters: ["id=1"]) {
id
name
}
}
Finally delete user.
mutation {
deleteUsers(filter: ["id=1"]) {
id
}
}
