display uploaded image in "all feed" page??

i cannot display the uploaded image document with the created status update in the 'all feed page" however, i was able to get it work in the show status page. modified this way in show.html.erb:

        <% if @status.document && @status.document.attachment? %>

        <%= image_tag @status.document.attachment.url(:medium) %><br />

        <%= status_document_link @status %>        
        <hr />
        <% end %>

putting the same code in the index.html.erb page generates: NoDocument Method error for document

any suggestion how to go about it?? thnx in advance

Hey arjun menon you may need to say "status" instead of "@status". Hope that helps!

nope that didnt work. was still getting d same error. but when i modified the application helper file to

    def status_document_link(status)
        if status.document && status.document.attachment?
            content_tag(:span, "Attachment", class: "label label-info") + 
            link_to(image_tag(status.document.attachment.url(:medium)), status.document.attachment.url) 
        end
    end

then it worked. wud appreciate explanation as to why that worked.
