How to use modal to create a new object in rails?

Question

This is the current situation, a general rails app with index.html.erb related to index action, and a new.html.erb with new action to create a new object.

My request is that I want to use modal to replace the index.html.erb to create a new object. In detail, when user click a New Button in the index.html page, a dialog display with a form of creating object, instead of opening the new.html page.

Is there a possible way to realise this ignoring copying the code in new.html.erb to index.html.erb? Because it would also move the code in new action to index action.

I have tried an approach below, but it didn't meet my requirement:

<%= link_to "New sites", new_site_path, :class => "btn btn-primary", "data-toggle" => "modal", "data-target" => ".bs-example-modal-lg" %>

It would open a modal dialog including the components in application.html.erb, such as navigation bar ,side bar and so on, not only the creating form.

you can set "layout false" in action
