Public Service Announcement
Public Service Announcement is a Rails Engine allowing for the centralized management of public alerts.
Add this line to your Gemfile:
Then at the commandline:
bundle install rake psa:migrations:copy rake db:migrate
Finally, add the code to output the messages to your application.html.erb file:
<ul class="announcements"> <% public_service_announcements.each do |announcement| %> <li><%= announcement %></li> <% end %> </ul>
And for haml:
%ul.announcements - public_service_announcements.each do |announcement| li=announcement
Of course, you can actually format them anyway you like but this is how I do it.
Create new announcement with a message, start date, and end date. You may, optionally, include max views, route regex to match, and/or user agent regex to match. The route and user agent regexes will default to exact match unless you specify either ^ or $.
