1、config.py
import os
basedir = os.path.abspath(os.path.dirname(file))
class Config:
SECRET_KEY = os.environ.get('SECRET_KEY') or 'hard to guess string'
SQLALCHEMY_COMMIT_ON_TEARDOWN = True
FLASKY_MAIL_SUBJECT_PREFIX = '[Flasky]'
FLASKY_MAIL_SENDER = 'Flasky Admin flasky@example.com'
FLASKY_ADMIN = os.environ.get('FLASKY_ADMIN')
@staticmethod
def init_app(app):
pass
class DevelopmentConfig(Config):
DEBUG = True
MAIL_SERVER = 'smtp.googlemail.com'
MAIL_PORT = 587
MAIL_USE_TLS = True
MAIL_USERNAME = os.environ.get('MAIL_USERNAME')
MAIL_PASSWORD = os.environ.get('MAIL_PASSWORD')
SQLALCHEMY_DATABASE_URI = os.environ.get('DEV_DATABASE_URL') or 'sqlite:///' + os.path.join(basedir, 'data-dev.sqlite')
class TestingConfig(Config):
TESTING = True
SQLALCHEMY_DATABASE_URI = os.environ.get('TEST_DATABASE_URL') or 'sqlite:///' + os.path.join(basedir, 'data-test.sqlite')
class ProductionConfig(Config):
SQLALCHEMY_DATABASE_URI = os.environ.get('DATABASE_URL') or 'sqlite:///' + os.path.join(basedir, 'data.sqlite')

config = {
'development': DevelopmentConfig,
'testing': TestingConfig,
'production': ProductionConfig,
'default': DevelopmentConfig
}

2、app/init.py
from flask import Flask, render_template
from flask.ext.bootstrap import Bootstrap
from flask.ext.mail import Mail
from flask.ext.moment import Moment
from flask.ext.sqlalchemy import SQLAlchemy
from config import config
from .main import main as main_blueprint
bootstrap = Bootstrap()
mail = Mail()
moment = Moment()
db = SQLAlchemy()
def create_app(config_name):
app = Flask(name)
app.config.from_object(config[config_name])
config[config_name].init_app(app)
bootstrap.init_app(app)
mail.init_app(app)
moment.init_app(app)
db.init_app(app)
#注册蓝本
app.register_blueprint(main_blueprint)
return app

3、 app/main/init.py ##创建蓝本
from flask import Blueprint
main = Blueprint('main', name)
from . import views, errors

4、 app/main/errors.py #@main.app_errorhandler(404)
from flask import render_template
from . import main
@main.app_errorhandler(404)
def page_not_found(e):
return render_template('404.html'), 404
@main.app_errorhandler(500)
def internal_server_error(e):
return render_template('500.html'), 500

5 app/main/views.py #定义程序路由
from datetime import datetime
from flask import render_template, session, redirect, url_for
from . import main
from .forms import NameForm
from .. import db
from ..models import User
@main.route('/', methods=['GET', 'POST'])
def index():
form = NameForm()
if form.validate_on_submit():
# ...
return redirect(url_for('main.index'))
return render_template('index.html',form=form, name=session.get('name'),known=session.get('known', False),current_time=datetime.utcnow())

6、 manage.py

!/usr/bin/env python

import os
from app import create_app, db
from app.models import User, Role
from flask.ext.script import Manager, Shell
from flask.ext.migrate import Migrate, MigrateCommand
app = create_app(os.getenv('FLASK_CONFIG') or 'default')
manager = Manager(app)
migrate = Migrate(app, db)

def make_shell_context():
return dict(app=app, db=db, User=User, Role=Role)
manager.add_command("shell", Shell(make_context=make_shell_context))
manager.add_command('db', MigrateCommand)

if name == 'main':
manager.run()

7、 建立需求文件：
pip freeze >requirements.txt
Flask==0.10.1
Flask-Bootstrap==3.0.3.1
Flask-Mail==0.9.0
Flask-Migrate==1.1.0
Flask-Moment==0.2.0
Flask-SQLAlchemy==1.0
Flask-Script==0.6.6
Flask-WTF==0.9.4
Jinja2==2.7.1
Mako==0.9.1
MarkupSafe==0.18
SQLAlchemy==0.8.4
WTForms==1.0.5
Werkzeug==0.9.4
alembic==0.6.2
blinker==1.3
itsdangerous==0.23

安装： pip install -r requirements.txt

8、 单元测试： tests/test_basics.py
import unittest
from flask import current_app
from app import create_app, db
class BasicsTestCase(unittest.TestCase):
def setUp(self):
self.app = create_app('testing')
self.app_context = self.app.app_context()
self.app_context.push()
db.create_all()
def tearDown(self):
db.session.remove()
db.drop_all()
self.app_context.pop()
def test_app_exists(self):
self.assertFalse(current_app is None)
def test_app_is_testing(self):
self.assertTrue(current_app.config['TESTING'])

manage.py 中启动单元测试

@manager.command
def test():
"""Run the unit tests."""
import unittest
tests = unittest.TestLoader().discover('tests')
unittest.TextTestRunner(verbosity=2).run(tests)

运行 ： python manage.py test

9、创建或更新数据库：
python manage.py db upgrade
