## Using custom object types as argument
|
||||
|

To use a custom object type as an argument, you need to inherit `graphene.InputObjectType`, not `graphene.ObjectType`.
|
||||
|
||||
```python
|
||||
class CustomArgumentObjectType(graphene.InputObjectType):

field1 = graphene.String()
|
||||
field2 = graphene.String()
|
||||
|
||||
```
|
||||
|
||||
Then, when defining this in an argument, you need to wrap it in an `Argument` object.
|
||||
|
||||
```python
|
||||
graphene.Field(graphene.String(), to=graphene.Argument(CustomArgumentObjectType))
|
||||
```

description: Details of how to perform filtering in Graphene Django
|

---
|
||||
|
||||
# Filtering
|
||||
|
||||
Graphene integrates with [django-filter](https://django-filter.readthedocs.org)
|
||||
to provide filtering of results. See the
|
||||
[usage documentation](https://django-filter.readthedocs.org/en/latest/usage.html#the-filter)
|
||||
for details on the format for `filter_fields`.
|
||||
|
||||
This filtering is only available when using the Django integrations
|
||||
(i.e. nodes which extend `DjangoNode`). Additionally `django-filter`
|
||||
is an optional dependency of Graphene. You will need to
|
||||
install it manually, which can be done as follows:
|
||||
|
||||
```bash
|
||||
# You'll need to django-filter
|
||||
pip install django-filter
|
||||
```
|
||||
|
||||
**Note: The techniques below are demoed in the
|
||||
[cookbook example app](https://github.com/graphql-python/graphene/tree/master/examples/cookbook_django).**
|
||||
|
||||
## Filterable fields
|
||||
|
||||
The `filter_fields` parameter is used to specify the fields which can be filtered upon.
|
||||
The value specified here is passed directly to `django-filter`, so see the
|
||||
[filtering documentation](https://django-filter.readthedocs.org/en/latest/usage.html#the-filter)
|
||||
for full details on the range of options available.
|
||||
|
||||
For example:
|
||||
|
||||
```python
|
||||
class AnimalNode(DjangoNode):
|
||||
class Meta:
|
||||
# Assume you have an Animal model defined with the following fields
|
||||
model = Animal
|
||||
filter_fields = ['name', 'genus', 'is_domesticated']
|
||||
|
||||
class Query(ObjectType):
|
||||
animal = relay.NodeField(AnimalNode)
|
||||
all_animals = DjangoFilterConnectionField(AnimalNode)
|
||||
```
|
||||
|
||||
You could then perform a query such as:
|
||||
|
||||
```graphql
|
||||
query {
|
||||
# Note that fields names become camelcased
|
||||
allAnimals(genus: "cat", isDomesticated: true) {
|
||||
edges {
|
||||
node {
|
||||
id,
|
||||
name
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
You can also make more complex lookup types available:
|
||||
|
||||
```python
|
||||
class AnimalNode(DjangoNode):
|
||||
class Meta:
|
||||
model = Animal
|
||||
# Provide more complex lookup types
|
||||
filter_fields = {
|
||||
'name': ['exact', 'icontains', 'istartswith'],
|
||||
'genus': ['exact'],
|
||||
'is_domesticated': ['exact'],
|
||||
}
|
||||
```
|
||||
|
||||
Which you could query as follows:
|
||||
|
||||
```graphql
|
||||
query {
|
||||
# Note that fields names become camelcased
|
||||
allAnimals(name_Icontains: "lion") {
|
||||
edges {
|
||||
node {
|
||||
id,
|
||||
name
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Orderable fields
|
||||
|
||||
Ordering can also be specified using `filter_order_by`. Like `filter_fields`,
|
||||
this value is also passed directly to `django-filter` as the `order_by` field.
|
||||
For full details see the
|
||||
[order_by documentation](https://django-filter.readthedocs.org/en/latest/usage.html#ordering-using-order-by).
|
||||
|
||||
For example:
|
||||
|
||||
```python
|
||||
class AnimalNode(DjangoNode):
|
||||
class Meta:
|
||||
model = Animal
|
||||
filter_fields = ['name', 'genus', 'is_domesticated']
|
||||
# Either a tuple/list of fields upon which ordering is allowed, or
|
||||
# True to allow filtering on all fields specified in filter_fields
|
||||
order_by_fields = True
|
||||
```
|
||||
|
||||
You can then control the ordering via the `orderBy` argument:
|
||||
|
||||
```graphql
|
||||
query {
|
||||
allAnimals(orderBy: "name") {
|
||||
edges {
|
||||
node {
|
||||
id,
|
||||
name
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Custom Filtersets
|
||||
|
||||
By default Graphene provides easy access to the most commonly used
|
||||
features of `django-filter`. This is done by transparently creating a
|
||||
`django_filters.FilterSet` class for you and passing in the values for
|
||||
`filter_fields` and `order_by_fields`.
|
||||
|
||||
However, you may find this to be insufficient. In these cases you can
|
||||
create your own `Filterset` as follows:
|
||||
|
||||
```python
|
||||
class AnimalNode(DjangoNode):
|
||||
class Meta:
|
||||
# Assume you have an Animal model defined with the following fields
|
||||
model = Animal
|
||||
filter_fields = ['name', 'genus', 'is_domesticated']
|
||||
|
||||
|
||||
class AnimalFilter(django_filters.FilterSet):
|
||||
# Do case-insensitive lookups on 'name'
|
||||
name = django_filters.CharFilter(lookup_type='iexact')
|
||||
|
||||
class Meta:
|
||||
model = Animal
|
||||
fields = ['name', 'genus', 'is_domesticated']
|
||||
|
||||
|
||||
class Query(ObjectType):
|
||||
animal = relay.NodeField(AnimalNode)
|
||||
# We specify our custom AnimalFilter using the filterset_class param
|
||||
all_animals = DjangoFilterConnectionField(AnimalNode,
|
||||
filterset_class=AnimalFilter)
|
||||
```

description: A Quick guide to Graphene in Django
|

---
|
||||
|
||||
# Django Tutorial
|
||||
|
||||
Graphene has a number of additional features that are designed to make
|
||||
working with Django *really simple*.
|
||||
|
||||
**Note: The code in this quickstart is pulled from the
|
||||
[cookbook example app](https://github.com/graphql-python/graphene/tree/master/examples/cookbook_django)**.
|
||||
|
||||
|
||||
## Setup the Django project
|
||||
|
||||
We will setup the project, create the following:
|
||||
|
||||
* A Django project called `cookbook`
|
||||
* An app within `cookbook` called `ingredients`
|
||||
|
||||
```bash
|
||||
# Create the project directory
|
||||
mkdir cookbook
|
||||
cd cookbook
|
||||
|
||||
# Create a virtualenv to isolate our package dependencies locally
|
||||
virtualenv env
|
||||
source env/bin/activate # On Windows use `env\Scripts\activate`
|
||||
|
||||
# Install Django and Graphene with Django support
|
||||
pip install django
|
||||
pip install graphene[django]
|
||||
pip install django-graphiql
|
||||
|
||||
# Set up a new project with a single application
|
||||
django-admin.py startproject cookbook . # Note the trailing '.' character
|
||||
django-admin.py startapp ingredients
|
||||
```
|
||||
|
||||
Now sync your database for the first time:
|
||||
|
||||
```bash
|
||||
python manage.py migrate
|
||||
```
|
||||
|
||||
Let's create a few simple models...
|
||||
|
||||
|
||||
## Defining our models
|
||||
|
||||
Let's get started with these models:
|
||||
|
||||
```python
|
||||
# cookbook/ingredients/models.py
|
||||
from django.db import models
|
||||
|
||||
|
||||
class Category(models.Model):
|
||||
name = models.CharField(max_length=100)
|
||||
|
||||
def __str__(self):
|
||||
return self.name
|
||||
|
||||
|
||||
class Ingredient(models.Model):
|
||||
name = models.CharField(max_length=100)
|
||||
notes = models.TextField()
|
||||
category = models.ForeignKey(Category, related_name='ingredients')
|
||||
|
||||
def __str__(self):
|
||||
return self.name
|
||||
```
|
||||
|
||||
## Schema
|
||||
|
||||
GraphQL presents your objects to the world as a graph structure rather than a more
|
||||
hierarchical structure to which you may be accustomed. In order to create this
|
||||
representation, Graphene needs to know about each *type* of object which will appear in
|
||||
the graph.
|
||||
|
||||
This graph also has a *root type* through which all access begins. This is the `Query` class below.
|
||||
In this example, we provide the ability to list all users via `all_users`, and the
|
||||
ability to obtain a specific user via `get_user`.
|
||||
|
||||
Create `cookbook/ingredients/schema.py` and type the following:
|
||||
|
||||
```python
|
||||
# cookbook/ingredients/schema.py
|
||||
from graphene import relay, ObjectType
|
||||
from graphene.contrib.django.filter import DjangoFilterConnectionField
|
||||
from graphene.contrib.django.types import DjangoNode
|
||||
|
||||
from cookbook.ingredients.models import Category, Ingredient
|
||||
|
||||
|
||||
# Graphene will automatically map the User model's fields onto the UserType.
|
||||
# This is configured in the UserType's Meta class (as you can see below)
|
||||
class CategoryNode(DjangoNode):
|
||||
class Meta:
|
||||
model = Category
|
||||
filter_fields = ['name', 'ingredients']
|
||||
filter_order_by = ['name']
|
||||
|
||||
|
||||
class IngredientNode(DjangoNode):
|
||||
class Meta:
|
||||
model = Ingredient
|
||||
# Allow for some more advanced filtering here
|
||||
filter_fields = {
|
||||
'name': ['exact', 'icontains', 'istartswith'],
|
||||
'notes': ['exact', 'icontains'],
|
||||
'category': ['exact'],
|
||||
'category__name': ['exact'],
|
||||
}
|
||||
filter_order_by = ['name', 'category__name']
|
||||
|
||||
|
||||
class Query(ObjectType):
|
||||
category = relay.NodeField(CategoryNode)
|
||||
all_categories = DjangoFilterConnectionField(CategoryNode)
|
||||
|
||||
ingredient = relay.NodeField(IngredientNode)
|
||||
all_ingredients = DjangoFilterConnectionField(IngredientNode)
|
||||
|
||||
class Meta:
|
||||
abstract = True
|
||||
```
|
||||
|
||||
The filtering functionality is provided by
|
||||
[django-filter](https://django-filter.readthedocs.org). See the
|
||||
[usage documentation](https://django-filter.readthedocs.org/en/latest/usage.html#the-filter)
|
||||
for details on the format for `filter_fields`.
|
||||
|
||||
Note that the above `Query` class is marked as 'abstract'. This is because we
|
||||
want will now create a project-level query which will combine all our app-level
|
||||
queries.
|
||||
|
||||
Create the parent project-level `cookbook/schema.py`:
|
||||
|
||||
```python
|
||||
import graphene
|
||||
|
||||
import cookbook.ingredients.schema
|
||||
|
||||
|
||||
class Query(cookbook.ingredients.schema.Query):
|
||||
# This class will inherit from multiple Queries
|
||||
# as we begin to add more apps to our project
|
||||
pass
|
||||
|
||||
schema = graphene.Schema(name='Cookbook Schema')
|
||||
schema.query = Query
|
||||
```
|
||||
|
||||
You can think of this as being something like your top-level `urls.py`
|
||||
file (although it currently lacks any namespacing).
|
||||
|
||||
## Adding GraphiQL
|
||||
|
||||
GraphiQL is a web-based integrated development environment to assist in the
|
||||
writing and executing of GraphQL queries. It will provide us with a simple
|
||||
and easy way of testing our cookbook project.
|
||||
|
||||
Add `django_graphiql` to `INSTALLED_APPS` in `cookbook/settings.py`:
|
||||
|
||||
```python
|
||||
INSTALLED_APPS = [
|
||||
...
|
||||
'django_graphiql',
|
||||
|
||||
# This will also make the `graphql_schema` management command available
|
||||
'graphene.contrib.django',
|
||||
]
|
||||
```
|
||||
|
||||
## Creating GraphQL and GraphiQL views
|
||||
|
||||
Unlike a RESTful API, there is only a single URL from which GraphQL is accessed.
|
||||
Requests to this URL are handled by Graphene's `GraphQLView` view.
|
||||
|
||||
Additionally, we'll add a URL for aforementioned GraphiQL, and for the Django admin
|
||||
interface (the latter can be useful for creating test data).
|
||||
|
||||
```python
|
||||
from django.conf.urls import url, include
|
||||
from django.contrib import admin
|
||||
from django.views.decorators.csrf import csrf_exempt
|
||||
|
||||
from graphene.contrib.django.views import GraphQLView
|
||||
|
||||
from cookbook.schema import schema
|
||||
|
||||
urlpatterns = [
|
||||
url(r'^admin/', admin.site.urls),
|
||||
url(r'^graphql', csrf_exempt(GraphQLView.as_view(schema=schema))),
|
||||
url(r'^graphiql', include('django_graphiql.urls')),
|
||||
]
|
||||
```
|
||||
|
||||
## Load some test data
|
||||
|
||||
Now is a good time to load up some test data. The easiest option will be to
|
||||
[download the ingredients.json](https://raw.githubusercontent.com/graphql-python/graphene/feature/django/examples/cookbook/cookbook/ingredients/fixtures/ingredients.json)
|
||||
fixture and place it in
|
||||
`cookbook/ingredients/fixtures/ingredients.json`. You can then run the following:
|
||||
|
||||
```
|
||||
$ python ./manage.py loaddata ingredients
|
||||
|
||||
Installed 6 object(s) from 1 fixture(s)
|
||||
```
|
||||
|
||||
Alternatively you can use the Django admin interface to create some data youself.
|
||||
You'll need to run the development server (see below), and create a login
|
||||
for yourself too (`./manage.py createsuperuser`).
|
||||
|
||||
## Testing our GraphQL schema
|
||||
|
||||
We're now ready to test the API we've built. Let's fire up the server from the command line.
|
||||
|
||||
```bash

Performing system checks...
|

Django version 1.9, using settings 'cookbook.settings'
|
||||
Starting development server at http://127.0.0.1:8000/
|
||||
Quit the server with CONTROL-C.
|
||||
```
|
||||
|
||||
Go to [localhost:8000/graphiql](http://localhost:8000/graphiql) and type your first query!
|
||||
|
||||
```graphql
|
||||
query {
|
||||
allIngredients {
|
||||
edges {
|
||||
node {
|
||||
id,
|
||||
name
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
The above will return the names & IDs for all ingredients. But perhaps you want
|
||||
a specific ingredient:
|
||||
|
||||
```graphql
|
||||
query {
|
||||
# Graphene creates globally unique IDs for all objects.
|
||||
# You may need to copy this value from the results of the first query
|
||||
ingredient(id: "SW5ncmVkaWVudE5vZGU6MQ==") {
|
||||
name
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
You can also get each ingredient for each category:
|
||||
|
||||
```graphql
|
||||
query {
|
||||
allCategories {
|
||||
edges {
|
||||
node {
|
||||
name,
|
||||
ingredients {
|
||||
edges {
|
||||
node {
|
||||
name
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Or you can get only 'meat' ingredients containing the letter 'e':
|
||||
|
||||
```graphql
|
||||
query {
|
||||
# You can also use `category: "CATEGORY GLOBAL ID"`
|
||||
allIngredients(name_Icontains: "e", categoryName: "Meat") {
|
||||
edges {
|
||||
node {
|
||||
name
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```

# Introspection Schema
|
||||
|
||||
Relay uses [Babel Relay Plugin](https://facebook.github.io/relay/docs/guides-babel-plugin.html)
|
||||
that requires you to provide your GraphQL schema data.
|
||||
|
||||
Graphene comes with a management command for Django to dump your schema data to
|
||||
`schema.json` that is compatible with babel-relay-plugin.
|
||||
|
||||
|
||||
## Usage
|
||||
|
||||
Include `graphene.django.contrib` to `INSTALLED_APPS` in you project settings:
|
||||
|
||||
```python
|
||||
INSTALLED_APPS += ('graphene.django.contrib')
|
||||
```
|
||||
|
||||
Assuming your Graphene schema is at `tutorial.quickstart.schema`, run the command:
|
||||
|
||||
```bash
|
||||
./manage.py graphql_schema --schema tutorial.quickstart.schema --out schema.json
|
||||
```
|
||||
|
||||
It dumps your full introspection schema to `schema.json` inside your project root
|
||||
directory. Point `babel-relay-plugin` to this file and you're ready to use Relay
|
||||
with Graphene GraphQL implementation.
|
||||
|
||||
|
||||
## Advanced Usage
|
||||
|
||||
To simplify the command to `./manage.py graphql_schema`, you can specify the
|
||||
parameters in your settings.py:
|
||||
|
||||
```python
|
||||
GRAPHENE_SCHEMA = 'tutorial.quickstart.schema'
|
||||
GRAPHENE_SCHEMA_OUTPUT = 'data/schema.json' # defaults to schema.json
|
||||
```
|
||||
|
||||
Running `./manage.py graphql_schema` dumps your schema to
|
||||
`<project root>/data/schema.json`.
|
||||
|
||||
|
||||
## Help
|
||||
|
||||
Run `./manage.py graphql_schema -h` for command usage.

# Django Tutorial
|
||||
|
||||
In our previous quickstart page we created a very simple schema.
|
||||
|
||||
Now we will adapt the schema to automatically map some Django models,
|
||||
and expose this schema in a `/graphql` API endpoint.
|
||||
|
||||
## Project setup
|
||||
|
||||
```bash
|
||||
# Create the project directory
|
||||
mkdir tutorial
|
||||
cd tutorial
|
||||
|
||||
# Create a virtualenv to isolate our package dependencies locally
|
||||
virtualenv env
|
||||
source env/bin/activate # On Windows use `env\Scripts\activate`
|
||||
|
||||
# Install Django and Graphene with Django support
|
||||
pip install django
|
||||
pip install graphene[django]
|
||||
pip install django-graphiql
|
||||
|
||||
# Set up a new project with a single application
|
||||
django-admin.py startproject tutorial . # Note the trailing '.' character
|
||||
django-admin.py startapp quickstart
|
||||
```
|
||||
|
||||
Now sync your database for the first time:
|
||||
|
||||
```bash
|
||||
python manage.py migrate
|
||||
```
|
||||
|
||||
We'll also create an initial user named `admin` with a password of `password`.
|
||||
|
||||
```bash
|
||||
python manage.py createsuperuser
|
||||
```
|
||||
|
||||
Once you've set up a database and initial user created and ready to go, open up the app's directory and we'll get coding...
|
||||
|
||||
|
||||
|
||||
## Schema
|
||||
|
||||
GraphQL presents your objects to the world as a graph structure rather than a more
|
||||
heiricarcal structure to which you may be acustomed. In order to create this
|
||||
representation, Graphene needs to know about each *type* of object which will appear in
|
||||
the graph. Below we define these as the `UserType` and `GroupType` classes.
|
||||
|
||||
This graph also has a 'root' through which all access begins. This is the `Query` class below.
|
||||
In this example, we provide the ability to list all users via `all_users`, and the
|
||||
ability to obtain a single user via `get_user`.
|
||||
|
||||
Open `tutorial/quickstart/schema.py` and type the following:
|
||||
|
||||
```python
|
||||
import graphene
|
||||
from graphene.contrib.django import DjangoObjectType
|
||||
|
||||
from django.contrib.auth.models import User, Group
|
||||
|
||||
# Graphene will automatically map the User model's fields onto the UserType.
|
||||
# This is configured in the UserType's Meta class
|
||||
class UserType(DjangoObjectType):
|
||||
class Meta:
|
||||
model = User
|
||||
only_fields = ('username', 'email', 'groups')
|
||||
|
||||
|
||||
class GroupType(DjangoObjectType):
|
||||
class Meta:
|
||||
model = Group
|
||||
only_fields = ('name', )
|
||||
|
||||
|
||||
class Query(graphene.ObjectType):
|
||||
all_users = graphene.List(UserType)
|
||||
get_user = graphene.Field(UserType,
|
||||
id=graphene.String().NonNull)
|
||||
get_group = graphene.Field(GroupType,
|
||||
id=graphene.String().NonNull)
|
||||
|
||||
def resolve_all_users(self, args, info):
|
||||
return User.objects.all()
|
||||
|
||||
def resolve_get_user(self, args, info):
|
||||
return User.objects.get(id=args.get('id'))
|
||||
|
||||
def resolve_get_group(self, args, info):
|
||||
return Group.objects.get(id=args.get('id'))
|
||||
|
||||
schema = graphene.Schema(query=Query)
|
||||
```
|
||||
|
||||
|
||||
## Adding GraphiQL
|
||||
|
||||
For having the GraphiQL static assets we need to append `django_graphiql` in `INSTALLED_APPS` in `tutorial/settings.py`:
|
||||
|
||||
```python
|
||||
INSTALLED_APPS = [
|
||||
# The other installed apps
|
||||
'django_graphiql',
|
||||
]
|
||||
```
|
||||
|
||||
## Creating GraphQL and GraphiQL views
|
||||
|
||||
Unlike a RESTful API, there is only a single URL from which a GraphQL is accessed.
|
||||
Requests to this URL are handled by Graphene's `GraphQLView` view.
|
||||
|
||||
Additionally, an interface for navigating this API will be very useful. Graphene
|
||||
includes the [graphiql](https://github.com/graphql/graphiql) in-browser IDE
|
||||
which assists in exploring and querying your new API. We’ll add a URL for this too.
|
||||
|
||||
```python
|
||||
from django.conf.urls import url, include
|
||||
from django.views.decorators.csrf import csrf_exempt
|
||||
from graphene.contrib.django.views import GraphQLView
|
||||
from quickstart.schema import schema
|
||||
|
||||
|
||||
# Wire up our GraphQL schema to /graphql.
|
||||
# Additionally, we include GraphiQL view for querying easily our schema.
|
||||
urlpatterns = [
|
||||
url(r'^graphql', csrf_exempt(GraphQLView.as_view(schema=schema))),
|
||||
url(r'^graphiql', include('django_graphiql.urls')),
|
||||
]
|
||||
```
|
||||
|
||||
## Testing our GraphQL schema
|
||||
|
||||
We're now ready to test the API we've built. Let's fire up the server from the command line.
|
||||
|
||||
```bash
|
||||
python ./manage.py runserver
|
||||
```
|
||||
|
||||
Go to [localhost:8080/graphiql](http://localhost:8080/graphiql) and type your first query!
|
||||
|
||||
```graphql
|
||||
myQuery {
|
||||
getUser(id:"1") {
|
||||
username
|
||||
}
|
||||
}
|
||||
```

Cookbook Example Django Project
|
||||
===============================
|
||||
|
||||
This example project demos integration between Graphene and Django.
|
||||
The project contains two apps, one named `ingredients` and another
|
||||
named `recepies`.
|
||||
|
||||
Getting started
|
||||
---------------
|
||||
|
||||
First you'll need to get the source of the project. Do this by cloning the
|
||||
whole Graphene repository:
|
||||
|
||||
```bash
|
||||
# Get the example project code
|
||||
git clone https://github.com/graphql-python/graphene.git
|
||||
cd graphene/examples/cookbook
|
||||
```
|
||||
|
||||
It is good idea (but not required) to create a virtual environment
|
||||
for this project. We'll do this using
|
||||
[virtualenv](http://docs.python-guide.org/en/latest/dev/virtualenvs/)
|
||||
to keep things simple,
|
||||
but you may also find something like
|
||||
[virtualenvwrapper](https://virtualenvwrapper.readthedocs.org/en/latest/)
|
||||
to be useful:
|
||||
|
||||
```bash
|
||||
# Create a virtualenv in which we can install the dependencies
|
||||
virtualenv env
|
||||
source env/bin/activate
|
||||
```
|
||||
|
||||
Now we can install our dependencies:
|
||||
|
||||
```bash
|
||||
pip install -r requirements.txt
|
||||
```
|
||||
|
||||
Now setup our database:
|
||||
|
||||
```bash
|
||||
# Setup the database
|
||||
./manage.py migrate
|
||||
|
||||
# Load some example data
|
||||
./manage.py loaddata ingredients
|
||||
|
||||
# Create an admin user (useful for logging into the admin UI
|
||||
# at http://127.0.0.1:8000/admin)
|
||||
./manage.py createsuperuser
|
||||
```
|
||||
|
||||
Now you should be ready to start the server:
|
||||
|
||||
```bash
|
||||
./manage.py runserver
|
||||
```
|
||||
|
||||
Now head on over to
|
||||
[http://127.0.0.1:8000/graphiql](http://127.0.0.1:8000/graphiql)
|
||||
and run some queries!
|
||||
(See the [Django quickstart guide](http://graphene-python.org/docs/quickstart-django/)
|
||||
for some example queries)
