Hi, I'm pleased to announce the release of Simpycity 2.0.0, a
database-respecting
object-relational mapper for PostgreSQL.
What Simpycity Is
-----------------
Simpycity is an object-relational mapper. It seamlessly maps PostgreSQL query
and function result sets to Python classes and class attributes.
It allows for the easy and rapid development of query- and
stored procedure-based data representations. Simpycity leverages PostgreSQL's
powerful composite type system, and the advanced type handling of the psycopg2
database access library.
What Simpycity is Not
---------------------
Simpycity is not a SQL generator and does not attempt to abstract or hide SQL.
Simpycity is designed for developers who deeply understand SQL and
desire to write the best possible SQL representations for their database.
Simpycity also rejects the Active Record paradigm, whose simplistic patterns
fail in even moderately complex systems.
Core Philosophy
---------------
The core philosophy behind Simpycity is that the Database and the Application
are separate entities, each with distinct abilities and design
representations; this echoes the classic Object versus Relation argument.
It provides a mechanism where a single business Object can easily represent
several Relations, and allow the base Relational layer to follow normal forms
without compromising or complicating application design.
Usage
=====
At its simplest, object-relation mapping looks like::
--SQL
create table foo (id int, name text);
insert into foo (id, name) values (1, 'one'), (2, 'two');
#Python
class Foo(simpycity.model.SimpleModel):
pg_type = ('public', 'foo')
__load__ = simpycity.core.QuerySingle('foo',['id'])
my_foo = Foo(1)
print(my_foo.name)
>>>one
