• GraphQL
• Django queryset love
• __getattr__ abuse
• ???
• Profit!!!

What

py2graphql is a Python GraphQL client that makes GraphQL feel better to use. It almost feels like you're using Django's ORM.

Installation

.. code-block:: bash :class: ignore

pip install py2graphql

Example

This Python equates to the following GraphQL.

.. code-block:: python :class: ignore

from py2graphql import Query

Query().repository(owner='juliuscaeser', name='rome').pullRequest(number=2).values('title', 'url').commits(last=250).edges.node.commit.values('id', 'message', 'messageBody')

.. code-block:: graphql :class: ignore

query { repository(owner: "juliuscaeser", name: "rome") { pullRequest(number: 2) { title url commits(last: 250) { edges { node { commit { id message messageBody } } } } } } }

You can even use the library to do the HTTP requests:

.. code-block:: python :class: ignore

from py2graphql import Client

headers = { 'Authorization': 'token MY_TOKEN', } Client(url=THE_URL, headers=headers).query().repository(owner='juliuscaeser', name='rome').fetch()

It also supports Mutations:

.. code-block:: python :class: ignore

from py2graphql import Client, Query

headers = { 'Authorization': 'token MY_TOKEN', } client = Client(url=THE_URL, headers=headers) mutation = Query(name='mutation', client=client)

And multiple queries in a single request:

.. code-block:: python :class: ignore

from py2graphql import Client, Query

headers = { 'Authorization': 'token MY_TOKEN', } query = Client(url=THE_URL, headers=headers).query().repository(owner='juliuscaeser', name='rome') query.pullRequest(number=2).values('title', 'url') query.releases(first=10).edges.node.values('name') query.get_graphql()

.. code-block:: graphql :class: ignore

query { repository(owner: "juliuscaeser", name: "rome") { pullRequest(number: 2) { title url } releases(first: 10) { edges { node { name } } } } }

As well as GraphQL errors:

.. code-block:: python :class: ignore

from py2graphql import Client, Query

headers = { 'Authorization': 'token MY_TOKEN', } result = Client(url=THE_URL, headers=headers).query().repository(owner='juliuscaeser', name='rome').fetch() result._errors [{'message': "Field 'repository' is missing required arguments: name", 'locations': [{'line': 7, 'column': 3}]}]
