bottle-sqlalchemy 0.3

SQLAlchemy integration for Bottle.

This bottle-sqlalchemy plugin integrates SQLAlchemy with your Bottle
application. It injects a SQLAlchemy session in your route and handle the session cycle.

Usage Example:

import bottle
from bottle import HTTPError
from bottle.ext import sqlalchemy
from sqlalchemy import create_engine, Column, Integer, Sequence, String
from sqlalchemy.ext.declarative import declarative_base

Base = declarative_base()
engine = create_engine('sqlite:///:memory:', echo=True)

app = bottle.Bottle()
plugin = sqlalchemy.Plugin(engine, Base.metadata, create=True)
app.install(plugin)

class Entity(Base):
__tablename__ = 'entity'
id = Column(Integer, Sequence('id_seq'), primary_key=True)
name = Column(String(50))

def __init__(self, name):
self.name = name

def __repr__(self):
return "<Entity('%d', '%s')>" % (self.id, self.name)


@app.get('/:name')
def show(name, db):
entity = db.query(Entity).filter_by(name=name).first()
if entity:
return {'id': entity.id, 'name': entity.name}
return HTTPError(404, 'Entity not found.')

@app.put('/:name')
def put_name(name, db):
entity = Entity(name)
db.add(entity)

@app.get('/spam/:eggs', sqlalchemy=dict(use_kwargs=True))
@bottle.view('some_view')
def route_with_view(eggs, db):
# do something useful here



It is up to you create engine and metadata, because SQLAlchemy has
a lot of options to do it. The plugin just handle the SQLAlchemy
session.
