A subset implementation of PostgREST.

You should read PostgREST and PonyORM first.

pip install pony-rest

Edit entities.py:

from pony.orm import *

db = Database()

class Person(db.Entity):
    name = Required(str)
    age = Required(int)
    cars = Set('Car')

class Car(db.Entity):
    make = Required(str)
    model = Required(str)
    owner = Required(Person)

then:

python -m pony_rest

or via wsgi:

gunicorn pony_rest

T=localhost:3333

# create new Person
curl -H 'content-type: application/json' -d '{"name": "foo", "age": 10}' $T/person

# read Person list
curl $T/person

# update Person where id is 1
curl -H 'content-type: application/json' -X PATCH -d '{"age": 10}' "$T/person?id=eq.1"

# delete Person where id is 1
curl -X DELETE "$T/person?id=eq.1"

Install module pyyaml, then create a configure file: database.yaml in your working directory, likes:

provider: sqlite
filename: ":memory:"
create_db: true
create_tables: true

...and see database.yaml in this repo to find more.

Note: only the first block configurations in yaml file is used for database, you could leave the old configurations in next blocks.
