Well, if you want to partial for each element, yo can do:
<%=render :partial=> 'logged', :collection=>@user.todos.logged %>
Or, if you want to pass the entire array to one instance, you can do
<%=render :partial=> 'logged', :object=>@user.todos.logged %>
In both cases, I assume that your object will be called logged.
, <%= logged.title %>, , .
