[PYTHON] Flask site construction memorandum

Directory structure

The basic configuration is as follows, and write the initial operation in \ __ init__.py under app.

root/ ┣run.py ┣app/ 　┣_init_.py 　┣config.py 　┣module1/ 　　┣_init_.py 　　┣models.py 　　┣controllers.py 　　┣forms.py 　┣templates/ 　┣static/

run.py

from app import create_app

if __name__ == "__main__":
    app = create_app()
    app.run()

app/__init__.pyy

from flask import Flask
from flask_debugtoolbar import DebugToolbarExtension
from flask.ext.sqlalchemy import SQLAlchemy # Import SQLAlchemy
from flask.ext.mongoengine import MongoEngine # Import Mongoengine
from flask.ext.admin import Admin
from app import config

# app setup
db = SQLAlchemy()
mongodb = MongoEngine()
admin = Admin()
toolbar = DebugToolbarExtension()

def create_app():

    app = Flask()
    app.config.config_from_object(config)

    #Initializing
    db.init_app(app)
    mongodb.init_app(app)
    admin.init_app(app)
    toolbar.init_app(app)

   # Import a module
    from app.module1.controllers import mod_app

    # Register blueprint(s)
    app.register_blueprint(mod_app)

    # Build the database:
    # This will create the database file using SQLAlchemy
    db.create_all()

    return app

If you do like this, you can specify url_prefix in each module and register with register_bluepoint. You can leave the config as a file, but in the case of windows etc., "../" is subtle, so I think it's better to import it and then read it as an object. Templates and satatic can be anywhere, but under the app is smart.
