below have in view file. root.html.slim

= render "layouts/alert"   .mainwrapper.cf   #workwrapper.cf     #intro       h1         | foriio platform creators.         br         | aim bring portfolio creators.       p         | think, shouldn’t matter whether can code or not.         br         | nor whether know how use photoshop.         br         | aim make things lot easier creators make portfolio.     #howto       ul         li.one-third.column           = image_tag "step1.png"           | 1. sign in facebook account         li.one-third.column           = image_tag "step2.png"           | 2. submit work, , portfolio ready!         li.one-third.column           = image_tag "step3.png"           | 3. tag collaborators such stylists, make artists, etc.           br           | or tag if involved!     h2.recenttitle recent uploads     ul#works       = render :partial => "works" 

this view file _works.html.slim

- @works.each | work |   = link_to work     li.works       span.thumb         = work_image_of work       h4 = link_to work.title, work, thumb:true       p.pull-left         small           = work.collaborators.count.to_s           | collaborators       p.pull-right         small           = link_to 'edit', edit_work_path(work) if can? :update, work           |            = link_to 'destroy', work, data: {:confirm => 'are sure?'}, :method => :delete  if can? :delete, work = paginate @works, remote: true 

i guessing 2 @works... , render :layout =>application.... can not co-exist??

how fix this??? thank in advance!

note: render :layout => 'application' loads header , rest of page.
