Answer 1

First, you should verify that your layout have jquery_ujs. Best practice to do it by including it in your main application.js:

//= require jquery_ujs

Check that you included application.js in your layout:

= javascript_include_tag :application

While, in development mode, view your source html and verify jquery_ujs.js exists.

Run your server and verify your link tag has data-confirm value, for example:

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

If all those steps are correct, everything should work!

Note: check this RailsCast http://railscasts.com/episodes/136-jquery-ajax-revised

I might be mistaken but you don't specify a controller along with the :action option. Have you tried the following? Assuming you have a messages resource configured in your route:

link_to 'Reset', message_path(@message), :confirm => 'Are you sure?'

EDIT: Above is deprecated. Rails 4.0 now accepts the prompt as a data attribute. See the doc here (Thanks @Ricky).

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

Answer 3

<%= link_to "Delete this article", article_path(article), method: :delete,
                    data: { confirm: "Are you sure you want to delete the 
                    article?"}, class: "btn btn-xs btn-danger" %>

A button link where article_path is the prefix and (article) is passing the id which is required by the method: :delete method. The later part of the codes adds a confirmation msg.

Can't remember how this was done in Rails 3, but in Rails 4 you can simply:

<%= link_to 'Reset message', { controller: 'your_controller', action: 'reset' }, data: {confirm: 'Are you sure?'} %>

Answer 5

Try this:

= link_to 'Reset message', {:action=>'reset'}, :confirm=>'Are you sure?'

or to be more clear

= link_to('Reset message', {:action=>'reset'}, {:confirm=>'Are you sure?'})

Refer http://api.rubyonrails.org/classes/ActionView/Helpers/UrlHelper.html#method-i-link_to

You will see that there are 3 parameters, when you are giving url as options like {:action => ..., :controller => ...}

link_to(body, url_options = {}, html_options = {})

In ruby, if the last parameter in a function call is a hash, you need not wrap it in {} characters (in other words, you can omit that in case, if the hash is the last parameter), so the code you have provided will be interpreted as a function call with only 2 parameters, 'Reset message' string and {:action=>'reset', :confirm=>'Are you sure?'} hash and the :confirm=>'Are you sure?' will be interpreted as a url_option instead of a html_option

Answer 6

Look at your javascript_include_tag and it should work fine:

<%= link_to("Reset message", :method => :reset, :class => 'action', :confirm => 'Are you sure?') %>
