Install from GitHub

You may also install Avo from GitHub but when you do that you must compile the assets yourself. You do that using the rake avo:build-assets command. When pushing to production, make sure you build the assets on deploy time using this task.

# Rakefile
Rake::Task["assets:precompile"].enhance do


If you don't have the assets:precompile step in your deployment process, please adjust that with a different step you might have like db:migrate.

Mount Avo to a subdomain

You can use the regular host constraint in the routes.rb file.

constraint host: 'avo' do
  mount Avo::Engine, at: '/'

Next steps

Please follow the next steps to ensure your app is secured and you have access to all the features you need.

  1. Set up authentication and tell Avo who is your current_user. This step is required for the authorization feature to work.
  2. Set up authorization. Don't let your data be exposed. Give users access to the data they need to see.
  3. Set up licensing.
