Rails 3 link_to (:method => :delete) not working

I'm having trouble with my verbs in Rails...

viewing a page for a resource (Dog) which has_many (Fleas). Embedded in dog's show.html.haml is a call to render @dog.fleas which automatically(?) finds & uses the template in "fleas/_flea.html.haml" to list each flea associated with said dog.

this displays correctly. whew! Now, next to each flea I've put a "Kill Flea" link that goes to a url: //localhost:3000/dogs/1/fleas/7. Which is generated by: 

= link_to("Kill Flea", [ flea.dog, flea ], :method => :delete, :confirm => "Sure? A bunny will die")

but every time that link is clicked there is no confirmation... and it renders the flea's show.html page. it's as if it's using GET on /dogs/1/fleas/7 instead of DELETE?!?

ps- not worried about spiders & robots deleting things in my database... i'm just trying to learn Rails..and understand what's happening

Check your <%= javascript_include_tag %> in application.html.erb

Perhaps you are missing the "application" js

It must look at least like

<%= javascript_include_tag "application" %>

Here I am not using the javascript_include_tag :all, :application etc. I am using my own js files, with another custom name: javascript_include_tag :my_custom_file and I also had this issue. And I am not using '= require jquery' in the file, but javascript/jquery is working. I think Rails includes jquery by default. What I done is I changed the 

link_to "Logout", destroy_user_session_path, :method => :delete

to

 form_tag destroy_user_session_path, :method => :delete, :id => "logout_form" 
   link_to 'Logout', "#delete", :onclick =>  "$('#logout_form').submit();"

Now its working fine.

check if application.html.erb

<%= javascript_include_tag :application %>

not as:

<%= javascript_include_tag :default %>

Hi you can also try this:

application.html.erb:

<%= javascript_include_tag 'jquery_ujs' %>

OR

<%= javascript_include_tag "http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js", "jquery.rails.js" %>

Rails 3 uses unobtrusive javascript now. In Rails 2.3, erb would just shove all that messy javascript right into the link itself, in an onClick event. Now the javascript has been moved out of the link, and into external js files. Make sure you have this in your layout:

<%= javascript_include_tag :all %>

If you do have this, there might be deeper problems keeping your javascript from running, but this is the place to start. Let me know how it turns out.

Looks like your link_to method isn't quite right. Try using this code instead:

  <%= link_to 'Kill Flea', [flea.dog, flea], :confirm => 'Sure?', :method => :delete %>
