如何部署具有工厂功能的Flask应用程序以创建应用程序

Question

我使用.wsgi文件中的以下配置成功地部署了一个带有wsgi和apache2的singleton flask应用程序。在

#!/usr/bin/python
import sys
import logging
logging.basicConfig(stream=sys.stderr)
sys.path.insert(0,"/var/www/Devrupt/")

from Devrupt import app as application
application.secret_key = 'Add your secret key'

activate_this = '/var/www/Devrupt/venv/bin/activate_this.py'
execfile(activate_this, dict(__file__=activate_this))

我的Apache2.conf文件：

如何使用工厂功能部署Flask应用程序以创建应用程序？在

带工厂功能结构的烧瓶应用：

| - Devrupt
    | - Devrupt
        |- app/
            |- templates/
            |- static/  
            |- main/
                |- __init__.py
                |- errors.py
                |- forms.py
                |- views.py
            |- __init__.py      # Factory Function
            |- models.py
        |- migrations/          # Contains the database migrations scripts
        |- tests/               # Where unit tests are written
            |- __init__.py
            |- test*.py
        |- venv/                # Contains the python virtual environment
        |- requirements.txt     # List package dependencies so that it is easy to regenerate an identical virtual environment on a diff machine
        |- config.py            # Stores the configuration settings
        |- manage.py            # Launch the application and other applcation tasks

| - devrupt.wsgi

mod_wsgi (Apache)声明“如果没有用于创建应用程序的工厂函数，而是一个单实例实例，则可以直接将其作为应用程序导入。”

app/init.py（工厂函数）：

# Application Package Constructor
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 config import config

bootstrap = Bootstrap()
moment = Moment()

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)
    moment.init_app(app)

    # Attach Routes and custom error messages here
    from .main import main as main_blueprint
    app.register_blueprint(main_blueprint)


return app

要使它在工厂函数应用程序中工作，我需要做些什么修改？在

您只需要确保您的.wsgi文件中有一个应用程序对象。可以使用工厂函数创建此对象。例如：

from Devrupt import application_factory
application = application_factory()

就这么简单！ 但要真正地阐明，修改德夫鲁普.wsgi收件人：
