Rails, def destroy, is not responding with the destroy.js.erb, why?

Question

Rails, def destroy, is not responding with the destroy.js.erb

Here is my method:

  # DELETE /Groups/1
  # DELETE /Groups/1.xml
  def destroy

    @group = Group.find(params[:id])
    @group.destroy

    respond_to do |format|
      format.js
    end
  end

In the view I have:

<a href="/groups/122" data-confirm="Are you sure?" data-method="delete" rel="nofollow" >Delete</a>

However on delete the log shows:

S

The destory.js.erb is never being called. Any ideas why? Thanks

ok, well, a couple of issues here:

first,

<a href="/groups/122" data-confirm="Are you sure?" data-method="delete" rel="nofollow" >Delete</a> 

this link is not remote, you can see it in the log you provided:

Processing by GroupsController#destroy as HTML

to make your link submit an ajax request add :remote => true ( the same way you already have :confirm => 'Are you sure?' and :method => :destroy )

second, you should disable layout rendering when responding with javascript.

So, your action might look like:

  respond_to do |format|
      format.js { render :template => 'groups/destroy.js.erb', :layout => false }
  end

To make it easier, I have added this to my contoller:

layout Proc.new { |controller| controller.request.xhr?? false : 'application' }

so that layout won't be rendered if request is of xhr type. Then you could leave you action as it is now and it should work
