Rails countdown gem or javascript

Question

Within my rails 4 app, i'm trying to set a countdown in one of my views.

I've tried using this gem: https://github.com/jnbt/countdown

In my gem file I added:

gem 'countdown'

I then ran bundle install which ran smoothly.

Then I added this in my application.js file:

//= require countdown

And then I tried running this from the terminal as instructed:

rails generate countdown:install

Which resulted in this error:

Could not find generator countdown:install

I then added this tag in my application.html.erb file:

<%= javascript_include_tag 'countdown' %>

And finally in my view, I added:

 <%= countdown Time.now + 28.hours %>

Which is giving me this error:

Sprockets::FileNotFound in Posts#index

couldn't find file 'countdown'

What is causing this? Is there any alternative to this gem? I would just like as simple countdown in my view. Can I just use some other javascript countdown? (I'm just worried about the countdown starting from when the user refreshes the browser, I need it to start from a permanent point, a particular date and time)

The docs say the generator file simply copies countdown.js to the public/javascripts directory. You should be able to do that yourself. Just copy the code at:

Create a file public/javascripts/countdown.js and paste in the code.
