Question

Please forgive me. I am definitely a beginner at Haml and Ruby on Rails. Anyway, I have a web application, where at the top of the page, I am keeping track of the various elements on the page. The code that renders this page is as follows:

  - if @item_collection.is_a?(Feature)
    = render 'edit_fields', :f => f
  - else
    = render 'fields', :f => f

For my page, the else clause would be executed. The code behind my page is:

.field.large
  = f.label      :name, nil, 'data-help-id' => 'page_name'
  = f.text_field :name, disabled_if_unauthorized(@item_collection, :maxlength => 255, :title => "Edit Page")
  = f.error_message_on(:name, :css_class => 'error_message')
.field
  = f.label      :path, nil, 'data-help-id' => 'page_path'
  = f.text_field :path, disabled_if_unauthorized(@item_collection, { :maxlength => 255, :class => 'extra_margin', :title => "Edit Page" })
  = f.error_message_on(:path, :css_class => 'error_message')
.field.info
  = f.label      'Info'
  %ul.elements_count
    %li.elements_in_use{ :id => 'elements_in_use'}
    %li.unused_elements{ :id => 'unused_elements'}
    %li.undefined_elements{ :id => 'undefined_elements'}

When the “Save” button is clicked, the unordered list (elements_count) disappears. I know it’s because I don’t have “f.” in front of those elements. The thing is, and again, forgive me because I’m just a beginner, putting “f.” in front of the list elements won’t work because %ul and %li are not Rails field helpers. Does anyone know what I can do to get these list elements to quit disappearing? Thanks!

You’re correct in that you don’t need ‘f’ in front of non rails form helpers.

Tried a similar setup to yours and I see the unordered list show up (with no content), do you see the list if you view source? Maybe a CSS file is hiding the bullets?
