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
