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 and Data Mapper paradigms, whose simplistic patterns fail in even moderately complex systems.
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.
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
