JSONAPI 1.0 server implementation for Flask.
This package requires at least python 3.7. To install run: pip install flask-jsonapi
. You can install SQLAlchemy support
with: pip install flask-jsonapi[sqlalchemy]
.
Full documentation is available at: https://flask-jsonapi.readthedocs.io/.
Let’s create a working example of a minimal Flask application. It will expose a single resource Article
as a REST
endpoint with fetch/create/update/delete operations. For persistence layer, it will use an in-memory SQLite database
with SQLAlchemy for storage.
import flask
import sqlalchemy
from sqlalchemy.orm import scoped_session
from sqlalchemy.orm import sessionmaker
from sqlalchemy.ext.declarative import declarative_base
from marshmallow_jsonapi import Schema, fields
import flask_jsonapi
from flask_jsonapi.resource_repositories import sqlalchemy_repositories
db_engine = sqlalchemy.create_engine('sqlite:///')
session = scoped_session(sessionmaker(bind=db_engine))
Base = declarative_base()
Base.query = session.query_property()
class Article(Base):
__tablename__ = 'articles'
id = sqlalchemy.Column(sqlalchemy.Integer, primary_key=True)
title = sqlalchemy.Column(sqlalchemy.String)
Base.metadata.create_all(db_engine)
class ArticleRepository(sqlalchemy_repositories.SqlAlchemyModelRepository):
model = Article
instance_name = 'articles'
session = session
class ArticleSchema(Schema):
id = fields.Int()
title = fields.Str()
class Meta:
type_ = 'articles'
strict = True
class ArticleRepositoryViewSet(flask_jsonapi.resource_repository_views.ResourceRepositoryViewSet):
schema = ArticleSchema
repository = ArticleRepository()
app = flask.Flask(__name__)
api = flask_jsonapi.Api(app)
api.repository(ArticleRepositoryViewSet(), 'articles', '/articles/')
app.run(host='127.0.0.1', port=5000)
Create a new Article
with title “First article”:
curl -H 'Content-Type: application/vnd.api+json' \
-H 'Accept: application/vnd.api+json' \
http://localhost:5000/articles/ \
--data '{"data": {"attributes": {"title": "First article"}, "type": "articles"}}' \
2>/dev/null | python -m json.tool
Result:
{
"data": {
"type": "articles",
"id": 1,
"attributes": {
"title": "First article"
}
},
"jsonapi": {
"version": "1.0"
}
}
Get the list of Articles
:
curl -H 'Accept: application/vnd.api+json' \
http://localhost:5000/articles/ \
2>/dev/null | python -m json.tool
Result:
{
"data": [
{
"type": "articles",
"id": 1,
"attributes": {
"title": "First article"
}
}
],
"jsonapi": {
"version": "1.0"
},
"meta": {
"count": 1
}
}
