For the most part, the only web pages in the shared folder will be purely static (404 user pages, FAQs, etc.). If you have static HTML that you want to display on a large number of pages, partial is what to look for.
Partial does not have to bind to the controller. You can create a subdirectory:
/views/static
and fill it with a whole piece of partial, so you will have:
/views/static/_my_first_partial.html.erb
/views/static/_my_second_partial.html.erb
, , :
render :partial => "static/my_first_partial"
, !
