Flask-PW 1.1.3

Settings

烧瓶pw设置（默认值）：

# Connection URI
PEEWEE_DATABASE_URI = 'sqlite:///peewee.sqlite'

# Connection params (for example for pgsql: { encoding: 'utf-8' })
PEEWEE_CONNECTION_PARAMS = {}

# Path to directory which contains migrations
PEEWEE_MIGRATE_DIR = 'migrations'

# Name of database table with migrations
PEEWEE_MIGRATE_TABLE = 'migratehistory'

# Path to module which contains you applications' Models
# Needed by automatic migrations
PEEWEE_MODELS_MODULE = ''

# Models which should be ignored in migrations
PEEWEE_MODELS_IGNORE = []

# Base models class
# Use `db.Model` as your models' base class for automatically DB binding
PEEWEE_MODELS_CLASS = <flask_pw.Model>

# Don't connect to db when request starts and close when it ends automatically
PEEWEE_MANUAL = False

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

如果使用烧瓶脚本，只需向管理器添加“db”命令即可：

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

并使用db create，db migrate和db rollback命令。

如果您使用flask>；=0.11将插件的命令连接到您的cli:

pw = Peewee(app)
app.cli.add_command(pw.cli, 'db')

if __name__ == '__main__':
    with app.app_context():
        app.cli()

Flask-Debugtoolbar

只需将flask pw.debugtoolbar.peeweedebugpanel添加到 应用程序配置：

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',
]

享受吧！
