Example

import peewee as pw
from flask import Flask

from flask_pw import Peewee


app = Flask(__name__)

app.config['PEEWEE_DATABASE_URI'] = 'sqlite:///:memory:'

db = Peewee(app)


class User(db.Model):

    name = pw.CharField(255)
    title = pw.CharField(127, null=True)
    active = pw.BooleanField(default=True)
    rating = pw.IntegerField(default=0)


@User.post_save.connect
def update(user, created=False):
    if created:
        # Do something

Migrations

If you use Flask-Script just add ‘db’ command to your manager:

manager = Manager(create_app)
manager.add_command('db', db.manager)

And use db create, db migrate and db rollback commands.

Flask-Debugtoolbar

Just add flask_pw.debugtoolbar.PeeweeDebugPanel to Flask-Debugtoolbar panels in your application’s configuration:

DEBUG_TB_PANELS = [
    'flask_debugtoolbar.panels.versions.VersionDebugPanel',
    'flask_debugtoolbar.panels.timer.TimerDebugPanel',
    'flask_debugtoolbar.panels.headers.HeaderDebugPanel',
    'flask_debugtoolbar.panels.request_vars.RequestVarsDebugPanel',
    'flask_debugtoolbar.panels.template.TemplateDebugPanel',
    'flask_debugtoolbar.panels.sqlalchemy.SQLAlchemyDebugPanel',
    'flask_debugtoolbar.panels.logger.LoggingPanel',
    'flask_debugtoolbar.panels.profiler.ProfilerDebugPanel',

    # Add the Peewee panel
    'flask_pw.flask_debugtoolbar.PeeweeDebugPanel',
]

Enjoy!
