I think it is appropriate for the view to call methods on the objects
passed in by the controller, provided that these methods do not change
the model or touch the database.

Example:
# controller
def my_action
@person = Person.find(params[:id])
end

#my_action.html.erb
Good: <%= @person.name >
Bad: <% @person.save! =>
Unspeakable: <% @people = Person.all %>
