|pypi-package| |build-status| |docs| |marshmallow3|
Flask-Marshmallow is a thin integration layer for Flask
_ (a Python web framework) and marshmallow
_ (an object serialization/deserialization library) that adds additional features to marshmallow, including URL and Hyperlinks fields for HATEOAS-ready APIs. It also (optionally) integrates with Flask-SQLAlchemy <http://flask-sqlalchemy.pocoo.org/>
_.
::
pip install flask-marshmallow
Create your app.
.. code-block:: python
from flask import Flask
from flask_marshmallow import Marshmallow
app = Flask(__name__)
ma = Marshmallow(app)
Write your models.
.. code-block:: python
from your_orm import Model, Column, Integer, String, DateTime
class User(Model):
email = Column(String)
password = Column(String)
date_created = Column(DateTime, auto_now_add=True)
Define your output format with marshmallow.
.. code-block:: python
class UserSchema(ma.Schema):
class Meta:
# Fields to expose
fields = ("email", "date_created", "_links")
# Smart hyperlinking
_links = ma.Hyperlinks(
{
"self": ma.URLFor("user_detail", values=dict(id="<id>")),
"collection": ma.URLFor("users"),
}
)
user_schema = UserSchema()
users_schema = UserSchema(many=True)
Output the data in your views.
.. code-block:: python
@app.route("/api/users/")
def users():
all_users = User.all()
return users_schema.dump(all_users)
@app.route("/api/users/<id>")
def user_detail(id):
user = User.get(id)
return user_schema.dump(user)
# {
# "email": "fred@queen.com",
# "date_created": "Fri, 25 Apr 2014 06:02:56 -0000",
# "_links": {
# "self": "/api/users/42",
# "collection": "/api/users/"
# }
