Chez Betty is a mini, cooperative food store where users can deposit money to their account and use it to purchase food and other items. The system is linked to the UMich ldap server so users can swipe their M-Card to login.
Chez Betty is written as a Python web app designed to run on a server with a browser based user interface. It supports cash and credit card deposits. The user interface expects a card swiper and barcode scanner to be attached to the machine. See the list at the end of this README for products we use. To test / demo the system without hardware, turn on "Demo mode" in the admin interface.
The Chez Betty application is developed using Python Pyramid. To get a development environment set up, do the following:
Clone this repository
git clone https://github.com/um-cseg/chez-betty.git
Install system dependencies:
# Ubuntu 15.10 sudo apt-get install postgresql postgresql-server-dev-9.4 libjpeg-dev # Ubuntu 16.10 sudo apt-get install postgresql postgresql-server-dev-9.5 libjpeg-dev
Setup virtualenv with Python3:
cd chez-betty # Python cannot decide on how it wants to do this. So # we have multiple iterations that we have tried. ## Way back: # virtualenv . ## Python3.3: # python3 -m venv . # ^ *not* pyvenv ., that installed python2 in my venv for w/e reason ## Newest (only do this with Python 3.4+): # pyvenv-3.5 venv ## Python 3.6 changes it again! python3.6 -m venv source venv/bin/activate
Install the dependencies:
# Note, this step *must* be run before setup.py. The latter will use # easy_install to install requirements instead of pip, which will # break some packages (e.g. stripe). The argument should be the root # directory of the project. pip install -e .
Setup the development environment
python setup.py develop
development.inito set config information and passwords.
cp development.ini.example development.ini [edit development.ini]
Setup the database:
python chezbetty/initializedb.py development.ini
Install bower and bower-install
# Note: Distro copies of node tend to fall behind really quickly. # You are better off using a copy of node/npm installed directly: # http://nodejs.org/ # https://github.com/npm/npm sudo npm install bower bower-installer -g
Get all css/js dependencies
Run the webserver:
pserve development.ini # n.b. pserve will be in your path if your virtualenv is active
