## Documentation

[Visit the documentation to get started!](https://docs.graphene-python.org/projects/django/en/latest/)

## Quickstart

For installing graphene, just run this command in your shell

```bash
pip install "graphene-django>=2.0"
```

### Settings

```python
INSTALLED_APPS = (
    # ...
    'django.contrib.staticfiles', # Required for GraphiQL
    'graphene_django',
)

GRAPHENE = {
    'SCHEMA': 'app.schema.schema' # Where your Graphene schema lives
}
```

### Urls

We need to set up a `GraphQL` endpoint in our Django app, so we can serve the queries.

```python
from django.urls import path
from graphene_django.views import GraphQLView

urlpatterns = [
    # ...
    path('graphql', GraphQLView.as_view(graphiql=True)),
]
```

## Examples

Here is a simple Django model:

```python
from django.db import models

class UserModel(models.Model):
    name = models.CharField(max_length=100)
    last_name = models.CharField(max_length=100)
```

To create a GraphQL schema for it you simply have to write the following:

```python
from graphene_django import DjangoObjectType
import graphene

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

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

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

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

Then you can query the schema:

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

Quickstart
----------

For installing graphene, just run this command in your shell

.. code:: bash

    pip install "graphene-django>=2.0"

Settings
~~~~~~~~

.. code:: python

    INSTALLED_APPS = (
        # ...
        'graphene_django',
    )

    GRAPHENE = {
        'SCHEMA': 'app.schema.schema' # Where your Graphene schema lives
    }

Urls
~~~~

We need to set up a ``GraphQL`` endpoint in our Django app, so we can
serve the queries.

.. code:: python

    from django.conf.urls import url
    from graphene_django.views import GraphQLView

    urlpatterns = [
        # ...
        url(r'^graphql$', GraphQLView.as_view(graphiql=True)),
    ]

Examples
--------

Here is a simple Django model:

.. code:: python

    from django.db import models

    class UserModel(models.Model):
        name = models.CharField(max_length=100)
        last_name = models.CharField(max_length=100)

To create a GraphQL schema for it you simply have to write the
following:

.. code:: python

    from graphene_django import DjangoObjectType
    import graphene

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

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

        @graphene.resolve_only_args
        def resolve_users(self):
            return UserModel.objects.all()

    schema = graphene.Schema(query=Query)

Then you can simply query the schema:

.. code:: python

    query = '''
        query {
          users {
            name,
            lastName
          }
        }
    '''
    result = schema.execute(query)
