Getting started
|
||
===============
|
||
|
||
Let’s build a basic GraphQL schema from scratch.
|
||
|
||
Requirements
|
||
------------
|
||
|
||
- Python (2.7, 3.2, 3.3, 3.4, 3.5, pypy)
|
||
- Graphene (1.0)
|
||
|
||
Project setup
|
||
-------------
|
||
|
||
.. code:: bash
|
||
|
||
pip install graphene --upgrade
|
||
|
||
Creating a basic Schema
|
||
-----------------------
|
||
|
||
A GraphQL schema describes your data model, and provides a GraphQL
|
||
server with an associated set of resolve methods that know how to fetch
|
||
data.
|
||
|
||
We are going to create a very simple schema, with a ``Query`` with only
|
||
one field: ``hello``. And when we query it should return ``"World"``.
|
||
|
||
.. code:: python
|
||
|
||
import graphene
|
||
|
||
class Query(graphene.ObjectType):
|
||
hello = graphene.String()
|
||
|
||
def resolve_hello(self, args, context, info):
|
||
return 'World'
|
||
|
||
schema = graphene.Schema(query=Query)
|
||
|
||
Querying
|
||
--------
|
||
|
||
Then, we can start querying our schema:
|
||
|
||
.. code:: python
|
||
|
||
result = schema.execute('{ hello }')
|
||
print result.data['hello'] # "World"
|
||
|
||
Congrats! You got your first graphene schema working!
