Sinatra can't serve JavaScript files without help? Is this correct?

Ok, so I'm not having trouble with this per say, but I want to make sure that I'm doing this right because it just seems like a lot of extra work in the long run.

I am working with Sinatra and using HAML templates. I want to include a JavaScript file from my HAML file. My directory structure looks like this:

• media/
  • js/
    • init.js (file I want to include)
  • css/
• models/
• views/
  • layout.haml
• routes/
• init.rb
• bootstrap.rb (included in init.rb)

When I try to include the file (with no extra routes or anything) I get a page cannot be found error. However, if I add this code, then it works fine:

get '/media/js/:name' do
    begin
        send_file('media/js/' + params[:name]开发者_StackOverflow)
    rescue
       "There's nothing for you here"
    end
end

I have no problem doing this for serving my media/static files, but I just want to make sure that this is necessary, I would like to avoid this is possible.

EDIT

I included the following code to my bootstrap.rb file, but to no avail:

set :root, File.dirname(__FILE__)
enable :static

From Sinatra's Website:

Static files are served from the ./public directory. You can specify a different location by setting the :public option:

set :public, File.dirname(__FILE__) + '/static'

You are serving from the media directory.
