Rails 4, Draper: authenticated user and views

Question

<% if user_signed_in? %>
    <!-- lots of html/erb -->
<% end %>

This view pattern seems to not separate concerns.

I wrap several views in my app with logic demanding the user is signed in and would instead like to separate concerns and put the <% if user_signed_in? %> logic where it belongs...this seems like a decorator thing to me (hence the Draper tag).

What is best practice here?

Not sure understood your question, but try to answer. At first to separate logic you dont need to use decorators in front of all, they serves for a little another thing. To separate logic you can use simple partials depending on current user state, for ex:

<% if user_signed_in? %>
    <%= render 'file_with_html_for_signed_user' %>
<% else %>
    <%= render 'file_with_html_for_non_signed_user' %>
<% end %>

You can declare this statement in your layouts/application.html.erb
