- Easy-To-Use TinyMCE Editor with Security Filtering and Image Uploader

Since Opal is highly customizable, you can use it for many different things:
- Content Management System(CMS)

- Review Website
Opal is available at the following places:
If you have git installed on your server, you can install it directly from Github:
git clone git://github.com/hulihanapplications/Opal.git
Install all of Opal’s required gems using bundler:
cd Opal bundle install
Next, Run the following command(while in the Opal directory) to install Opal’s database schema in production mode:
bundle exec rake db:migrate RAILS_ENV=production LOCALE=en bundle exec rake db:seed RAILS_ENV=production LOCALE=en
This command will install all of Opal’s required gems(via bundler) and create the database structure of Opal inside the production database. If you leave out RAILS_ENV=PRODUCTION, everything will be installed into your development database instead. This command will also set up the default admin account, some sample items(you’ll be asked if you want to install sample Data), and other stuff to help you get started with Opal. You can also specify the LOCALE parameter to install Opal in a language other than english.
- If you want to automate an Opal installation, or if you just want to bypass prompts(that ask you if you want to install sample data and other stuff: run this command: rake opal:install PROMPTS=FALSE)
You can now start Opal using the built-in Rails webserver, WEBrick…
rails s -e production
…or any of your other favorite webservers: apache, mongrel, nginx, etc.
- To log in to Opal for the first time, the default Admin username and password is: admin.
Opal includes an automated email system that will send you emails whenever someone registers, creates a new item, etc.
To use this automated email system, you must configure the config/email.yml file to connect to an SMTP email server. Here’s an example of what this file should look like:
development: :address: smtp.server.com :port: 25 :authentication: plain :user_name: user :password: pass production: :address: smtp.server.com :port: 25 :authentication: plain :user_name: user :password: pass
You can easily extend and customize Opal with new plugins and themes. Check out Opal’s Project Page to learn more.
