如何使用工厂功能部署Flask应用程序以创建应用程序

Question

我已使用.wsgi文件中的以下配置设法使用wsgi和apache2部署单瓶版本应用程序。

#!/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：

<VirtualHost *:80>
        ServerName devrupt.com
        ServerAdmin lui@devrupt.com
        WSGIScriptAlias / /var/www/Devrupt/devrupt.wsgi
        <Directory /var/www/Devrupt/Devrupt/>
                Order allow,deny
                Allow from all
        </Directory>
        Alias /static /var/www/Devrupt/Devrupt/static
        <Directory /var/www/Devrupt/Devrupt/static/>
                Order allow,deny
                Allow from all
        </Directory>
        ErrorLog ${APACHE_LOG_DIR}/error.log
        LogLevel warn
        CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

如何使用工厂功能部署Flask应用程序以创建应用程序？

具有工厂功能结构的Flask应用程序：

| - 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)表示＆＃34;如果您没有用于创建应用程序的工厂函数，而是单例实例，则可以直接将其作为应用程序导入。＆＃34;

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

我必须做些哪些修改才能使其在工厂功能应用程序上工作？
