Flask application with a Form, Model, Database (SQLAlchemy for ORM). Uses modules structure rather than a package structure.

app.py

from flask import Flask, url_for

from flask import request, render_template, flash, redirect
from forms import BizForm, AddBiz
from flask.ext.sqlalchemy import SQLAlchemy
from flask.ext.security import Security, utils
from contextlib import closing
from datetime import date

import forms

# Create app and load the config
app = Flask(__name__)
app.config.from_object('config')

# connect to the database
db = SQLAlchemy(app)

# the "models" import SHOULD be after the above "db" assignment 
import models
# 'from models import *' works but 'from models import Business' does NOT work
# dont know why!
from models import *

# run db.create_all before running the app to create DB Tables
