You need a different method to render this, or if it will only ever appear in the modal, then you need to add layout: false to your controller so it doesn't render the whole page. Make sure that your `show` template only renders the stuff that will appear within the modal, nothing else, and then turn off the layout so you don't get the entire page.

If the modals will be the only consumer of the "remote: true" requests, then you can make that change in your show controller method, like this:

def show
#whatever else you regularly have here
respond_to do |format|
format.html { }
format.js { layout: false, template: 'modal' }
end
end

# views/posts/modal.html.erb

<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
<h4><%= @post.title %></h4>
</div>
<div class="modal-body">
<%= @post.whatever_else_you_want_to_render %>
</div>
<div class="modal-footer">
<button class="btn btn-default" data-dismiss="modal">Close</button>
</div>
