To build your own app, first clone this repo somewhere and cd into it.

git clone https://github.com/timabe/pies
cd pies

Next you'll create a python virtual environment and install the requirements

pip install virtualenv
virtualenv venv
source venv/bin/activate
pip install -r requirements.txt

First create the local database and add the Pies menu

python manage.py shell
>>> db.create_all()
>>> Pies.add_menu()
>>> quit()

Now you can run and play around with the functionality. Just run python manage.py runserver and navigate to http://127.0.0.1:5000/ or localhost:5000 in a browser.

Sign up for a free Heroku account if you don't have one. Once you've done that, download their command line tools.

Log into your account in a terminal window.

# log in and enter credentials
heroku login
# create an app. This creates the URL and a git repo
heroku create <optional-name>
# add your db
heroku addons:add heroku-postgresql:hobby-dev
# set up some heroku environment vars
heroku config:set FLASK_CONFIG=heroku
heroku config:set SECRET_KEY=<your secret key>
# push your code to the remote heroku git repo
git push heroku master
# now you can deploy the app!
heroku run python manage.py deploy --make_menu --seed

Once you've run that, you should be able to visit the url they gave you, which should look something like this https://<app_name>.herokuapp.com and open up the application.

If you want to delete the app just run heroku apps:destroy <YOUR APP NAME>

I would not have been able to create this app without relying heavily on the Flask tutorials and books written by Miguel Grinberg. Most of the code in this app is forked from his wonderful tutorial on building a microblogging service. For a great, comprehensive guide on building apps with the Flask framework, check out his tutorial and buy his O'Reily book, they are both great.
