PublicLab.org

The content management system for the Public Lab research community, the plots2 web application is a combination of a group research blog of what we call "research notes," and a wiki.

It features a Bootstrap-based UI and a variety of community and attribution features that help the Public Lab community collaborate on environmental technology design and documentation, as well as community organizing. Originally a Drupal site, it was rewritten in 2012 in Ruby on Rails, and has since extended but not entirely replaced the legacy Drupal data model and database design.

Some key features include:

• a Markdown-based research note and wiki editor
• wiki editing and revision tracking
• tagging and tag-based content organization
• email notification subscriptions for tags and comments
• a barebones search interface
• a user dashboard presenting recent activity

Prerequisites

Database

Our production application runs on mysql, but for development, sqlite3 is sufficient.

• Mac OS X: Macs ship with sqlite3 already installed.
• Ubuntu/Debian: sudo apt-get install sqlite3
• Fedora/Red Hat/CentOS: sudo yum install sqlite -- you may need sqlite-devel as well.

Image libraries

If you are just developing and don't plan to do work with image uploading, you may not need the following, but otherwise:

sudo apt-get install imagemagick ruby-rmagick

Ruby

Install rvm for Ruby management (http://rvm.io)

curl -L https://get.rvm.io | bash -s stable

Note: At this point during the process, you may want to log out and log back in, or open a new terminal window; RVM will then properly load in your environment.

Ubuntu users: You may need to enable Run command as a login shell in Ubuntu's Terminal, under Edit > Profile Preferences > Title and Command. Then close the terminal and reopen it. You may also want to run source ~/.rvm/scripts/rvm to load RVM.

Then, use RVM to install version 2.1.2 of Ruby. (v1.9.3+ should also work):

rvm install 2.1.2

Gems with Bundler

Ruby dependencies, or Gems, are managed with Bundler.

gem install bundler - if it's not already installed, but it should be in a basic RVM ruby.

Assets with Bower

You'll also need bower which is available through npm, part of node.js.

This wiki page from the nodejs repository has comprehensive and up to date installation guides for many systems.

Once NPM is installed, you should be able to run:

sudo npm install -g bower

phantomjs for javascript tests

We are using jasmine-rails gem for javascript tests which require phantomjs for headless testing. Generally the phantomjs gem gets installed along with the jasmine-rails gem. If the package installation for the gem fails you can use this script to install it.

But some architectures don't support the phantomjs gem. For those you have to run phantomjs via its binary.You can find the installation instructions in its official build documentation. For Ubuntu/debian based system you can follow these instructions or use the script mentioned there. On successful installation you can see the version number of phantomjs with the phantomjs -v command. For the binary to work properly with jasmine-rails change the line 52 on spec/javascripts/support/jasmine.yml to use_phantom_gem: false.

Please report any error regarding phantomjs installation in the github issue tracker. We will try to solve it as fast as possible.

##Installation

Installation steps:

1. In the console, download a copy of the source with git clone https://github.com/publiclab/plots2.git.
2. Enter the new plots2 directory with cd plots2.
3. Install gems with bundle install --without production from the rails root folder, to install the gems you'll need, excluding those needed only in production. You may need to first run bundle update if you have older gems in your environment from previous Rails work.
4. Make a copy of db/schema.rb.example and place it at db/schema.rb.
5. Make a copy of config/database.yml.sqlite.example and place it at config/database.yml
6. Run rake db:setup to set up the database
7. Install static assets (like external javascript libraries, fonts) with bower install
8. Start rails with passenger start from the Rails root and open http://localhost:3000 in a web browser.
9. Wheeeee! You're up and running! Log in with test usernames "user", "moderator", or "admin", and password "password".
10. Run rake test:all to confirm that your install is working properly. For some setups, you may see warnings even if test pass; see this issue we're working to resolve.

Bundle exec

For some, it will be necessary to prepend your gem-related commands with bundle exec, for example bundle exec passenger start; adding bundle exec ensures you're using the version of passenger you just installed with Bundler. bundle exec rake db:setup, bundle exec rake db:seed are other examples of where this might be necessary.

##Testing

Run tests with rake test:all for running all tests. We are extremely interested in building our out test suite, so please consider helping us write tests!

Run only rails tests with rake test.

Client-side code is tested using Jasmine in jasmine-rails. You can run tests by navigating to /specs/ in the browser. Headless, or command-line test running may be possible with rake spec:javascript if you have phantomjs installed.

###Internationalization

Publiclab.org now supports Internationalization and localization, though we are in the initial stages. This has been accomplished with rails-I8n.

To see it in action, click on the 'Language' dropdown located in the header/footer section of the page. All the guidelines and best practices for I18n can be found here.

Translations are arranged in the yaml files here, which are organized in the similar way to views files. An example for adding translations can be found here.

To add new languages or for additional support, please write to [email protected]
