sandman2 automagically generates a RESTful API service from your existing database,
without requiring you to write a line of code. Simply point
sandman2 to your
database, add salt for seasoning, and voila!, a fully RESTful API service with
hypermedia support starts running, ready to accept HTTP requests.
This is a big deal. It means every single database you interact with, from the
SQLite database that houses your web browser's data up to your production
PostgreSQL server can be endowed with a REST API and accessed programatically,
using any number of HTTP client libraries available in every language.
sandman2 frees your data.
Imagine you're working for AnonymousCorp and need to access Group Y's data, which is presented to you through some horrible API or GUI. Wouldn't it be nice if you could just interact with that database through a REST API?
More than that, imagine if you could interact with the database through a REST
API and no one had to write any code. Not you. Not Group Y. No one.
That means no boilerplate ORM code, no database
connection logic. Nothing.
sandman2 can be run as a command-line tool
sandman2ctl) that just takes your database information as parameters and
connects to it, introspects the schema, generates a RESTful API, and starts the server.
What Happened to Sandman (1)?
sandman, the precursor to
sandman2, is no longer being maintained.
sandman had almost identical
functionality but had an architecture that reflected the capabilities of the underlying ORM, SQLAlchemy. As of the
0.9 release, SQLAlchemy
automap construct. This fundamentally changed the way that
sandman could interact with the underlying database in a
way that greatly simplified things. All that was needed was the actual effort to rewrite
sandman from scratch...
After wrestling with the idea for a while, I finally gave in and started the
sandman2 is that project. While I'll continue to support
sandman in the nearterm,
sandman2 definitely represents the way forward.
sandman2 is not yet at feature parity with the original
should be soon. Getting there is currently the top priority.
$ pip install sandman2. This provides the script
sandman2ctl, which just takes the database URI string, described here. For example, to connect to a SQLite database in the same directory you're running the script, you would run:
$ sandman2ctl sqlite+pysqlite:///database_file_name
To connect to a PostgreSQL database, make sure you install a driver like
pip, then use the following connection string:
$ sandman2ctl postgresql+psycopg2://scott:tiger@localhost/mydatabase
Again, see the SQLAlchemy documentation for a more comprehensive discussion of connection strings.
sandman2 supports all databases that the underlying ORM, SQLAlchemy, supports.
Presently, that includes:
- Microsoft SQL Server
Third-party packages extend support to:
- IBM DB2
- Amazon Redshift
- SQL Anywhere
One of the best things about the original
sandman was the Admin Interface. Not only does
sandman2 include the Admin Interface, but it modernizes it as well. The layout has been greatly improved, especially when dealing with larger numbers of tables. All of the original functionality of the Admin Interface remains unchanged.
Here's a shot of the new look:
sandman2ctl doesn't give you fine-grained enough control over your REST
endpoints, or you'd like to restrict the set of tables made available via
sandman2ctl, you can easily integrate
sandman2 into your application. See
the documentation for more info.
