I think you want to restructure your code a bit. For example, create
an instance method on household for retrieving a view object given a
year. Assuming you had a helper function or a partial for displaying
views your partial for displaying a household wouldn't need to be much
more complicated than

<%= format_view household.view_for_year @year %>

<%= format_view household.view_for_year @year - 1%>

<%= format_view household.view_for_year @year - 2%>
