About those one-liners… How about turning this:
<% if logged_in? %>
<p><%= link_to 'Edit', document_edit_path(@document) %></p>
<% end %>into this:
<%= content_tag 'p', link_to('Edit', document_edit_path(@document)) if logged_in? %>I don’t know about you, but to say that I’m impressed would be not enough. Available from Rails 2.0 upwards.
