Changelog

###V1.0.3

  • Renamed repo to Flask Engine
    • Run git remote set-url upstream https://github.com/zachwill/flask-engine

Sorry about any headaches this causes, but the name gae-flask-html5 had become
a little too verbose. You can still git pull upstream from any changes/updates
I make – just make sure you either git remote set-url or do the following:
git remote rm upstream and then git remote add upstream https://github.com/zachwill/flask-engine.

###V1.0.2

  • Minor fixes to views.py file.
  • Ajax functionality for adding todos.

###V1.0.1

  • Fixed bug with werkzeug_debugger_appengine submodule.
  • Minor changes to files (fixed grammar issues, deleted comments, etc).

V1.0

  • Added send email functionality.
    • NOTE: You’ll have to update the from_address variable in views.py
      for it to work properly.
    • Don’t forget to run the development server with the
      dev_appserver.py --enable_sendmail . command.
  • Added test.py file for running unittest. Deleted gaeunit.py.
    • Tests kept in tests directory.
    • Now uses GAE v1.4.3’s testbed functionality.

What is this?

It’s just a simple Flask skeleton for
Google App Engine,
but made with all the baked-in-goodness of
html5 boilerplate.

I’m planning on using this for my GAE projects going forward (I really
like the speed of Flask compared to
Django-Nonrel
on GAE), so I thought someone else might find it useful, too.

Just about everything is ready to go right out of the box – including
QUnit for JavaScript tests and a tests directory for Python’s unittest.
Also, I included a style.less file since I primarily only use the
Less.app when writing stylesheets nowadays.

Why should I use it?

I stumbled a bit figuring out how to add tests and use the unittest module,
and also setup an appengine_console.py file to connect to GAE’s remote API,
so this skeleton might come in handy for you.

I looked at two other Flask GAE skeletons on Github
(flask-gae-skeleton
and flask-gae-template
– both of which were awesome for learning), and I adapted what
I felt were some of their best parts. Recently, I’ve updated this project’s
structure after browsing the source code of
another GAE project skeleton.

Lastly, as an added bonus, the scripts are PEP8 compliant.

How do I use it?

Make sure you have the Google App Engine SDK
installed on your computer, and you’ve created an application for your
Google account. The SDK will also install symlinks to its packages on your
computer.

Steps to Get Up and Running

  1. Create a new application on Google App Engine.

  2. git clone this repo into your personal project folder.

  3. Amend the app.yaml file with your application’s name.

  4. Run the project from your development server (use the dev_appserver.py .
    command or use the Google App Engine Launcher GUI).

  5. Browse the sample application in your web browser: http://localhost:8080

  6. Once you’re ready to read the source code, check out the app directory.

  7. All static media is stored in the static directory.

    • This includes your favicon, robots.txt, and humans.txt
  8. Before you deploy, don’t forget to:

    • Update the humans.txt file.
    • Uncomment the default_expiration in app.yaml
    • Change the SECRET_KEY in settings.py using Python’s os.urandom function.

    >>> import os
    >>> os.urandom(24)
    '\xfd{H\xe5<\x95\xf9\xe3\x96.5\xd1\x01O

Useful Commands

Setup

git clone https://github.com/zachwill/flask-engine.git <your_app_name_here>

Run

dev_appserver.py .

If you’re planning on using email functionality with the development server,
use the following command:

dev_appserver.py --enable_sendmail .

Deploy

appcfg.py update .

Test

Tests are written using GAE v1.4.3’s testbed functionality. Currently, there
is a known bug
for users without PIL installed.

python test.py

Remote Console

python appengine_console.py <your_app_name_here>

Todo

  • add more tests
  • add pep8.py to libs
    • create PEP8 TestCase, too
