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,

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

     <% end %>

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

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

     <% end %>

  5. Assigning temporar temporary variables

     <% indicator_id = "loading_indicator_#{}" %><%=
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)
