# Graphene-Mongo

A [Mongoengine](https://mongoengine-odm.readthedocs.io/) integration for [Graphene](http://graphene-python.org/).

## Installation

For installing graphene-mongo, just run this command in your shell

```
pip install graphene-mongo
```

## Examples

Here is a simple Mongoengine model as `models.py`:

```python
from mongoengine import Document
from mongoengine.fields import StringField


class User(Document):
    meta = {'collection': 'user'}
    first_name = StringField(required=True)
    last_name = StringField(required=True)
```

To create a GraphQL schema and sync executor; for it you simply have to write the following:

```python
import graphene

from graphene_mongo import MongoengineObjectType

from .models import User as UserModel


class User(MongoengineObjectType):
    class Meta:
        model = UserModel


class Query(graphene.ObjectType):
    users = graphene.List(User)

    def resolve_users(self, info):
        return list(UserModel.objects.all())


schema = graphene.Schema(query=Query)
```

Then you can simply query the schema:

```python
query = '''
    query {
        users {
            firstName,
            lastName
        }
    }
'''
result = await schema.execute(query)
```

To create a GraphQL schema and async executor; for it you simply have to write the following:

```python
import graphene

from graphene_mongo import AsyncMongoengineObjectType
from graphene_mongo.utils import sync_to_async
from concurrent.futures import ThreadPoolExecutor

from .models import User as UserModel


class User(AsyncMongoengineObjectType):
    class Meta:
        model = UserModel


class Query(graphene.ObjectType):
    users = graphene.List(User)

    async def resolve_users(self, info):
        return await sync_to_async(list, thread_sensitive=False,
                             executor=ThreadPoolExecutor())(UserModel.objects.all())


schema = graphene.Schema(query=Query)
```

Then you can simply query the schema:

```python
query = '''
    query {
        users {
            firstName,
            lastName
        }
    }
'''
result = await schema.execute_async(query)
```
