How to refresh the browser with JS after clicking a link_to tag in a Rails app

I'm trying to refresh the browser after the user clicks a link to an action that updates the database.

I want to avoid using redirect_back to prevent being sent back to the top of the screen after reload so I'm adding a JS click listener to the link_to tag with a code like this:

# in my view
<h5 class='my-link'><%= link_to 'vote', vote_path' %></h5>

# at the bottom of my application layout
<script>
$('.my-link').click(function (event) {
window.location.reload(true);
});
</script>


The JS code listener works OK in that if I click on any section of the h5 element the page will reload. However, when I click in the link the application will go to the relevant controller#action but the page wont reload.

I'm assuming I'm missing a way to execute first the link action and then force the refresh. So at click the app records a vote and then JS force a reload. Can you see any way I can achieve this? Thanks.

UPDATE

I some what solved this issue by adding a timer to the JS event so it gives time for the link to reach the controller and do the action and do the reload after it.

<script>
$(document).ready(function() {
$('.puke-icon, .clean-link, .comment-send').click(function() {
setTimeout(function(){
window.location.reload(true); },
50);
});

});
</script>


This is probably too hacky so hopefully you can provide more elegant approaches thanks!

Answer

In your vote controller action, use location.reload() in respond_to do format.

respond_to do |format|
    format.js {render inline: "location.reload();" }
end

View:

<h5 class='my-link'><%= link_to 'vote', vote_path' %></h5>

Controller:

class VotesController < ApplicationController

  def vote
    ----------------------  

    // your code goes here

    ----------------------  

    respond_to do |format|
    format.js {render inline: "location.reload();" }
    end

  end

end

This will reload the page after the database action is completed.
