## Contributing
After cloning this repo, ensure dependencies are installed by running:
After cloning this repo, create a [virtualenv](https://virtualenv.pypa.io/en/stable/) and ensure dependencies are installed by running:
```sh
virtualenv venv
source venv/bin/activate
pip install -e ".[test]"
```
After developing, the full test suite can be evaluated by running:
Well-written tests and maintaining good test coverage is important to this project. While developing, run new and existing tests with:
```sh
py.test graphene --cov=graphene --benchmark-skip # Use -v -s for verbose mode
py.test PATH/TO/MY/DIR/test_test.py # Single file
py.test PATH/TO/MY/DIR/ # All tests in directory
```
Add the `-s` flag if you have introduced breakpoints into the code for debugging.
Add the `-v` ("verbose") flag to get more detailed test output. For even more detailed output, use `-vv`.
Check out the [pytest documentation](https://docs.pytest.org/en/latest/) for more options and test running controls.
You can also run the benchmarks with:
```sh
py.test graphene --benchmark-only
```
Graphene supports several versions of Python. To make sure that changes do not break compatibility with any of those versions, we use `tox` to create virtualenvs for each python version and run tests with that version. To run against all python versions defined in the `tox.ini` config file, just run:
```sh
tox
```
If you wish to run against a specific version defined in the `tox.ini` file:
```sh
tox -e py36
```
Tox can only use whatever versions of python are installed on your system. When you create a pull request, Travis will also be running the same tests and report the results, so there is no need for potential contributors to try to install every single version of python on their own system ahead of time. We appreciate opening issues and pull requests to make graphene even more stable & useful!

Interfaces
==========
An Interface contains the essential fields that will be implemented by
multiple ObjectTypes.
An *Interface* is an abstract type that defines a certain set of fields that a
type must include to implement the interface.
The basics:
- Each Interface is a Python class that inherits from ``graphene.Interface``.
- Each attribute of the Interface represents a GraphQL field.
Quick example
-------------
This example model defines a ``Character`` interface with a name. ``Human``
and ``Droid`` are two implementations of that interface.
For example, you can define an Interface ``Character`` that represents any
character in the Star Wars trilogy:
.. code:: python
import graphene
class Character(graphene.Interface):
name = graphene.String()
id = graphene.ID(required=True)
name = graphene.String(required=True)
friends = graphene.List(lambda: Character)
Any ObjectType that implements ``Character`` will have these exact fields, with
these arguments and return types.
For example, here are some types that might implement ``Character``:
.. code:: python
# Human is a Character implementation
class Human(graphene.ObjectType):
class Meta:
interfaces = (Character, )
born_in = graphene.String()
starships = graphene.List(Starship)
home_planet = graphene.String()
# Droid is a Character implementation
class Droid(graphene.ObjectType):
class Meta:
interfaces = (Character, )
function = graphene.String()
primary_function = graphene.String()
``name`` is a field on the ``Character`` interface that will also exist on both
the ``Human`` and ``Droid`` ObjectTypes (as those implement the ``Character``
interface). Each ObjectType may define additional fields.
Both of these types have all of the fields from the ``Character`` interface,
but also bring in extra fields, ``home_planet``, ``starships`` and
``primary_function``, that are specific to that particular type of character.
The above types have the following representation in a schema:
The full GraphQL schema defition will look like this:
.. code::
interface Character {
name: String
}
type Droid implements Character {
name: String
function: String
id: ID!
name: String!
friends: [Character]
}
type Human implements Character {
name: String
bornIn: String
id: ID!
name: String!
friends: [Character]
starships: [Starship]
homePlanet: String
}
type Droid implements Character {
id: ID!
name: String!
friends: [Character]
primaryFunction: String
}
Interfaces are useful when you want to return an object or set of objects,
which might be of several different types.
For example, you can define a field ``hero`` that resolves to any
``Character``, depending on the episode, like this:
.. code:: python
class Query(graphene.ObjectType):
hero = graphene.Field(
Character,
required=True,
episode=graphene.Int(required=True)
)
def resolve_hero(_, info, episode):
# Luke is the hero of Episode V
if episode == 5:
return get_human(name='Luke Skywalker')
return get_droid(name='R2-D2')
schema = graphene.Schema(query=Query, types=[Human, Droid])
This allows you to directly query for fields that exist on the Character interface
as well as selecting specific fields on any type that implments the interface
using `inline fragments <https://graphql.org/learn/queries/#inline-fragments>`_.
For example, the following query:
.. code::
query HeroForEpisode($episode: Int!) {
hero(episode: $episode) {
__typename
name
... on Droid {
primaryFunction
}
... on Human {
homePlanet
}
}
}
Will return the following data with variables ``{ "episode": 4 }``:
.. code:: json
{
"data": {
"hero": {
"__typename": "Droid",
"name": "R2-D2",
"primaryFunction": "Astromech"
}
}
}
And different data with the variables ``{ "episode": 5 }``:
.. code:: json
{
"data": {
"hero": {
"__typename": "Human",
"name": "Luke Skywalker",
"homePlanet": "Tatooine"
}
}
}
Resolving data objects to types
-------------------------------
As you build out your schema in Graphene it's common for your resolvers to
return objects that represent the data backing your GraphQL types rather than
instances of the Graphene types (e.g. Django or SQLAlchemy models). This works
well with ``ObjectType`` and ``Scalar`` fields, however when you start using
Interfaces you might come across this error:
.. code::
"Abstract type Character must resolve to an Object type at runtime for field Query.hero ..."
This happens because Graphene doesn't have enough information to convert the
data object into a Graphene type needed to resolve the ``Interface``. To solve
this you can define a ``resolve_type`` class method on the ``Interface`` which
maps a data object to a Graphene type:
.. code:: python
class Character(graphene.Interface):
id = graphene.ID(required=True)
name = graphene.String(required=True)
@classmethod
def resolve_type(cls, instance, info):
if instance.type == 'DROID':
return Droid
return Human
