OpenCongress - a Ruby on Rails application for displaying information about Congress

Lighthouse Project Page

OpenCongress for Developers


Getting started with our code

A. Dependencies

Start by installing all the packages required by OpenCongress.

For Ubuntu:

sudo apt-get install postgresql postgresql-client postgresql-contrib libpq-dev ruby1.8 ruby1.8-dev rubygems libopenssl-ruby imagemagick libmagick9-dev gcj-4.4-jre

or Mac OS X, start by installing MacPorts, then run:

sudo port install postgresql84 postgresql84-doc postgresql84-server ImageMagick md5sha1sum wget

Follow the instructions from the port install for initializing your database


Then grab the gems you need:



sudo gem install rails bluecloth mediacloth hpricot htree jammit json pg RedCloth ruby-openid simple-rss rmagick htmlentities oauth

Note for OS X: You may need to specify additional compile options for the pg gem. Make sure pg_config is in PATH and run sudo env ARCHFLAGS="-arch x86_64" gem install pg

B. Database setup

Switch to the postgres user and setup a db user following prompts for password and superuser.

sudo su postgres
createuser opencongress -P

Create your database

createdb opencongress_development -O opencongress

Import the tsearch2 backwards compatibility lib from wherever your postgres contribs got installed.

psql opencongress_development < /your/install/share/postgresql/contrib/8.4/tsearch2.sql

exit postgres user

C. App Setup

Copy over example yml files in /config

cd config; for file in `ls *example*`; do cp $file `expr "$file" : '\([^-\.]*\)'`.yml; done

Edit database.yml:

development:
adapter: postgresql
database: opencongress_development
username: opencongress
password: (password from step B)
host: localhost

Now you can start the solr server and run the database migrations

cd ..;rake solr:start
rake db:structure:load
rake db:seed

D. Data

create some dirs for data

Make sure all your data paths are set and exist in your environment file then run rake update:all to fetch and parse all available data sources. This process will take a very long time. Take a look at /lib/tasks/daily.rake for all the rake tasks if you want to run them individually.

Now just a script/server and you should be running
