Active Invoices is a very simple Ruby on Rails invoicing application, built using the amazing active_admin gem.
Clone the repository:
git clone https://github.com/ianmurrays/active_invoices
And run the following commands:
bundle install rake db:schema:load # or you can run rake db:migrate
You're going to need to create a user on the database using
rails console >> AdminUser.create! :email => "firstname.lastname@example.org", :password => "admin", :password_confirmation => "admin", :admin => true
You'll need to generate the assets for Active_admin:
rails g active_admin:assets
rails server and point your server to http://localhost:3000 and try out your new installation.
