Get started

Create virtual environment with 3.10 since modelresolvers require 3.10 and above

pipenv --python 3.10

Activate virtual environment

pipenv shell

Install modelresolvers

pipenv install modelresolvers

main.py

import strawberry

from modelresolvers import ModelResolvers, Schema

@strawberry.type
class User:
    firstname: str
    lastname: str


users = [
    User(firstname="John", lastname="Doe"),
    User(firstname="Jahe", lastname="Doe"),
]


@user_resolvers.query(name="user")
def user() -> User:
    return users[0]


@user_resolvers.mutation(name="add_user")
def add_user(firstname: str, lastname: str) -> User:
    user = User(firstname=firstname, lastname=lastname)
    users.append(user)
    return user

We are going to run the app by strawberry so we need strawberry schema. modelresolvers Schema converts its schema to strawberry schema. modelresolvers Schema has an attribute called strawberry_schema. So we will run the app based on strawberry schema

schema = Schema(models_resolvers=[user_resolvers]).strawberry_schema

The entire code is below.

main.py

import strawberry
from modelresolvers import ModelResolvers, Schema


user_resolvers = ModelResolvers()


@strawberry.type
class User:
    firstname: str
    lastname: str


users = [
    User(firstname="John", lastname="Doe"),
    User(firstname="Jahe", lastname="Doe"),
]


@user_resolvers.query(name="user")
def user() -> User:
    return users[0]


@user_resolvers.mutation(name="add_user")
def add_user(firstname: str, lastname: str) -> User:
    user = User(firstname=firstname, lastname=lastname)
    users.append(user)
    return user


schema = Schema(models_resolvers=[user_resolvers]).strawberry_schema

Run the app in your terminal

strawberry server main

Go to http://0.0.0.0:8000/graphql and run your mutations and queries.
