Bad Smells sing in a rails application

Hi all,

   Sometime ago, i read the slides "when V is for Vexing: Patterns to
DRY Up Your Views" (Bruce Williams railsconf). They are not online
anymore. I post one slide in my[1}.. But only the bad smells sign in
the view, and only problem, not the solution. here they are

   1. Calling find on a model directly

      <% Sales Sales.find_all_by_region(params[:region]).each .do |t| %><

      % end %>

   2. Calling find on an association

   3. Conditionally inserting content if/else clauses, case statements, etc

      <% if current_user.admin? %>Admins see this

      <% end %>

   4. Doing a complex inline ma map, sor sort, t, select, etc on a collection

      <% applications.sort_by{|app| [app.priority, app.creator.name]
}.each do |app|

      <% end %>

   5. Assigning temporar temporary variables

      <% indicator_id = "loading_indicator_#{item.id}" %><%=
link_to_remote("Show Status",:url => item_path(item),

      :loading => "$('#{indicator_id}').show()",

      :complete => "$('#{indicator_id}').hide()",

      ) %>

      <%= image_tag('progress.gif', :id => indicator_id)%>

I would like to ask for new bad smell signs. In the view, in the
controller or in the model. (and discuss this , specially number 3)

Thanks
