This is Gittip, a gift economy. Gittip is a cooperative escrow agent for recurring micro-gifts, or tips. Possible tip amounts per week are 0.00, 0.08, 0.16, 0.32, 0.64, and 1.28. Friday is payday. On Friday, we charge people's credit cards and the money goes into Gittip's (Zeta's) bank account. Money is allocated to other participants according to tips. Participants may withdraw money at any time, though this is currently quite manual. Installation ============ The site is built with Python 2.7 and the Aspen web framework, and is hosted on Heroku. Samurai is used for credit card processing, and Google for analytics. You need python2.7 on your PATH. You need Postgres with headers installed. There's a simple Makefile for building the software. All Python dependencies are included in vendor/. To `make run` you need a local.env file in the distribution root with these keys: CANONICAL_HOST= CANONICAL_SCHEME=http DATABASE_URL=postgres://user:pass@localhost/dbname SAMURAI_MERCHANT_KEY= SAMURAI_MERCHANT_PASSWORD= SAMURAI_PROCESSOR_TOKEN= GITHUB_CLIENT_ID=3785a9ac30df99feeef5 GITHUB_CLIENT_SECRET=e69825fafa163a0b0b6d2424c107a49333d46985 GITHUB_CALLBACK=http://localhost:8537/github/associate DYLD_LIBRARY_PATH=/Library/PostgreSQL/9.1/lib The SAMURAI_* keys are problematic. I need to think about how to handle that safely. The site works without them, except for the credit card page (you have to set them but you can set them to the empty string). The GITHUB_* keys are for a gittip-dev application in the Gittip organization on Github. It points back to localhost:8537, which is where Gittip will be running if you start it locally with `make run`. The DYLD_LIBRARY_PATH thing is to get psycopg2 working on Mac OS with EnterpriseDB's Postgres 9.1 installer. Setting up the Database ----------------------- The schema for the Gittip.com database is defined in sql/schema.sql. Here's how to install it: $ psql --user postgres Password for user postgres: psql (9.1.3) Type "help" for help. postgres=# create database gittip; CREATE DATABASE postgres=# \c gittip You are now connected to database "gittip" as user "postgres". gittip=# \i sql/schema.sql ... The best version of Postgres to use is 9.1, because gittip uses the hstore extension for unstructured data, and that isn't bundled with earlier versions. If you need to make schema changes or work on the credit card workflow then talk to me (@whit537) and we'll figure out how to get you what you need.
