Eve Peewee extension

A WIP data layer for Eve using peewee

Currently peewee creates tables based on settings.py DOMAIN declarations during start-up and basic Eve CRUD methods work.

Instuctions

python setup.py install or pip install eve-peewee
define DATABASE_URI in settings.py (see examples)
Eve(data=EvePeewee).run()

Tested

postgres 9.x, sqlite3
python 2.7, 3.5
basic eve functionality (filtering, sorting, pagination, timestamps, etag/if-match, soft delete)
1:m data relationships

Untested/TBD

mysql
custom validator
constraints (unique)
m:m data relationships (atm creates link tables but likely fails to query for embedding)
versioning fields

Notable caveats

peewee doesn't do auto-migration (if you change domain models, drop the tables to get them recreated or apply changes in db manually)
peewee specific field properties can be defined in DOMAIN schema (requires "transparent_schema_rules"), e.g. '_peewee': { 'primary_key': True }
not all possible error cases are captured to json/xml document, default 500 response may happen
objectid and media types are unsupported (list and dict types are saved as jsonb)
many of the mongo centric field properties of eve (anyof, allof etc) are silently ignored
