Answer 3

First, we need to understand what Js package respond to this kind of alerts in rails application. So for this, jquery_ujs package is reponsible for showing the alerts in rails.

So you must have jquery & jquery_ujs in your application.js file.

//= require jquery
//= require jquery_ujs

Now, we need to confirm, that application.js file is included in your required layout or not. By default layout file remains in application.html.erb in layout folder of views.

<%= javascript_include_tag 'application' %>

Next the link should have data-confirm & data-method attributes as

<a href="/message/1/reset" data-method="delete" data-confirm="Are you sure?">

In erb, this can be written as,

= link_to 'Reset', message_path(@message), data: {method: 'delete', confirm: 'Are you sure?'}

This should work if everything is aligned in same fashion.
