**sandman** "makes things REST". Have an existing database you'd like to
expose via a REST API? Normally, you'd have to write a ton of
boilerplate code for the ORM you're using, then integrate that into some
web framework.
I don't want to write boilerplate.
Here's what's required to create a RESTful API service from an existing
database using **sandman**:
.. code:: python
from sandman import app, db
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///chinook'
from sandman.model import register, Model
class Artist(Model):
__tablename__ = 'Artist'
class Album(Model):
__tablename__ = 'Album'
class Playlist(Model):
__tablename__ = 'Playlist'
register((Artist, Album, Playlist))
app.run()
Let's start our new service and make a request. While we're at it, lets
make use of Sandman's awesome filtering capability by specifying a
filter term:
.. code:: zsh
> python runserver.py &
* Running on http://127.0.0.1:5000/
> curl GET "http://localhost:5000/artists?Name=AC/DC"
.. code:: json
...
{
"resources": [
{
"ArtistId": 1,
"Name": "AC/DC",
"links": [
{
"rel": "self",
"uri": "/artists/1"
}
]
}
]
}
All of that, including filtering/searching, is automagically available
from those 10 measly lines of code.
Oh, that's not enough? You also want a Django-style admin interface
built automatically? Fine. Add one more line to the list of models to
get access to this:
.. figure:: /docs/images/admin_tracks_improved.jpg
:alt: improved admin interface screenshot

With **sandman**, (almost) zero boilerplate code is required. Your
existing database structure and schema is introspected and your database
tables magically get a RESTful API and admin interface. For each table,
Sandman creates:
- proper endpoints
- support for a configurable set of HTTP verbs
- GET
- POST
- PATCH
- PUT
- DELETE
- responses with appropriate ``rel`` links automatically
- foreign keys in your tables are represented by link
- custom validation by simply defining ``validate_<METHOD>`` methods on
your Model
- explicitly list supported methods for a Model by setting the
``__methods__`` attribute
- customize a Models endpoint by setting the ``__endpoint__`` method
- essentially a HATEOAS-based service sitting in front of your database
*Warning: Sandman is still very much a work in progress. Use it at your
own risk. It's also often changing in backwards incompatible ways.*
Installation
~~~~~~~~~~~~
``pip install sandman``
Quickstart
~~~~~~~~~~
You'll need to create one file with the following contents (which I call
``runserver.py``):
.. code:: python
from sandman.model import register, Model
# Insert Models here
# Register models here
# register((Model1, Model2, Model3))
# or
# register(Model1)
# register(Model2)
# register(Model3)
from sandman import app, db
app.config['SQLALCHEMY_DATABASE_URI'] = '<your database connection string (using SQLAlchemy)>'
app.run()
Then simply run
.. code:: bash
python runserver.py
and try curling your new RESTful API!
Example Application
~~~~~~~~~~~~~~~~~~~
Take a look in the ``sandman/test`` directory. The application found
there makes use of the `Chinook <http://chinookdatabase.codeplex.com>`__
sample SQL database.
Coming Soon
