Ruby on Rails tutorial errors

I am doing a Rails tutorial for a blog and I am getting 2 errors. When you generate the new site in order to have the pages show up you need to change 'application' to 'default' under the layout. That works fine but I believe it is creating a new error and it won't run the 'destroy' .js action. Instead, when you go to delete the post it uses a 'get' method and just links to the posts page (no deleting it).

Here is the error: (if you notice it goes to default.js)

My problem is that I don't know how to either get the pages to show up using the 'application' instead of 'default' which looks like:

<%= stylesheet_link_tag    'default', media: 'all', 'data-turbolinks-track' => true %>
    <%= javascript_include_tag 'default', 'data-turbolinks-track' => true %>

or how to get the js to execute correctly.
