rails 3 destroy action fails

The destroy action:

def destroy
  @tag = Tag.find(params[:id])
  @tag.destroy

  respond_to do |format|
    format.html { redirect_to(tags_url) }
    format.xml  { head :ok }
  end
end

The link:

<a href="/tags/14" data-confirm="Are you sure?" data-method="delete" rel="nofollow">Destroy</a>

Clicking it renders the show action.

Started GET "/tags/14" for 127.0.0.1 at Wed Oct 27 18:36:41 -0500 2010

javascript_include_tag :defaults is included on my page and the script tags render correct开发者_Go百科ly. Firebug doesn't give me any errors. This occurs in both Firefox and Opera.

It's probably how you are writing your link_to method.

 <%= link_to "Destroy", tag, :method => :delete, :confirm => "Really?" %>

Try that.

Make sure you have the resource declared in your routes.rb file as that is what gives this freebee urls.

in 2.3.8 it is

map.resources :tags

in R3 I don't really know but the guides have it like this

resources :tags

To use method overriding you need to be sending the _method parameter. For an action like destroy it should be a form that you POST with the _method parameter set to delete, you can construct the form in JS when you click the link if you like.
