How to run heroku restart from inside of a rails app? - ruby-on-rails

Question

I understand that from the console I can run heroku restart. What I'd like to do is to have a button in my app (admin console), where pushing that button runs a heroku restart. Does anyone know how to do that and if it's possible? So the code would look something like this:
<button id="heroku_restart">Restart</button>
$("#heroku_restart").click(function() {
$.post('/restart', {}).done(function(response) {
alert(response)
})
})
class AdminsController
# this is the action mapped to the route /restart
def restart
# code for heroku restart
end
end

So per #vpibano, as of this writing, doing it with the platform-api is a breeze. Here's the action POSTed to by a button on my website:
def restart
heroku = PlatformAPI.connect_oauth(ENV["heroku_oauth_token"])
heroku.dyno.restart_all("lastmingear")
render nothing: true
end

As per the description mentioned in the post, the one way of doing it is :
1) First locate the server.pid file
pid_file = Rails.root.join("tmp", "pids", "server.opid")
2) Now, truncate the contents of the file
File.open(pid_file, "w") {|f| f.truncate(0)}
3) Finally, run the server using Kernel module:
Kernel.exec("rails s")
Note: As rightly, mentioned by #vpibano you will need authentication to access your app.
This is not a working model but a way to achieve the requirement.
Hope it helps!!
