Why is my .db file not being created? I am using Flask SQLAlchemy, but I am having some problems. Here is my code:
from flask import Flask, render_template
from flask_sqlalchemy import SQLAlchemy
app = Flask(__name__)
app.config["SQLALCHEMY_DATABASE_URI"] = 'sqlite:///test.db'
db = SQLAlchemy(app)
It runs without error, but the .db file is not being created. Any ideas why?

Treehouse Moderator 68,426 PointsYou are almost there. From the quickstart document page it says:
To create the initial database, just import the db object from an interactive Python shell and run the
SQLAlchemy.create_all() method to create the tables and database:
>>> from yourapplication import db
>>> db.create_all()
So if you above file is called myapp.py you would use: from myapp import db
The db is the object you created in file myapp.py, line 9.
Post back if you need more help. Good luck!!
