Altro errore: can't dup Symbol

Eccomi di nuovo qui…

sembra che tutto giri quando mi inchiodo con un “can’t dup symbols”…
ho cercato su google l’errore ma c’è una sola segnalazione e non sembra
fare al caso mio.

Disastro…

Se qualcuno mi dà una mano…grazie in anticipo

#controller

def download
send_file(params[:path_to_file], :disposition => :attachment)
end

#view

<% @atts.each do |att| %>
<% uscore = “_”
pathFile = “#{Attachment::EXTENDEDPATH
}#{att.idext.to_s}#{uscore}#{att.categoria}#{uscore}#{att.nome}#{uscore}#{att.nomeoriginale}”%>

  • <%=h att.didascalia %>, <%=h att.nomeoriginale%>    <% form_tag :controller => 'attachments', :action => 'download' do %> <%= hidden_field_tag 'path_to_file', pathFile %> <%=submit_tag 'SCARICA', :id => "search-submit-attach" %> <% end %> <%= link_to image_tag("delete.gif", :border=>0), att, :confirm => 'Sicuri ?', :method => :delete %>
  • <% end %>

    Request

    Parameters:

    {“authenticity_token”=>“yWBu7XdV55PJDz6gNV5WEj90bCbOFvrNMAf034gMLNw=”,
    “path_to_file”=>“F:/rubyProjects/fg/public/uploads/5_1_1281281804_filmDaScaricare.txt”,
    “commit”=>“SCARICA”}

    Ma quella è la view del metodo download o di un altro metodo?

    penso che :disposition voglia una string e non un symbol prova…

    Hai ragione, ho messo string e funzionaaaaaaaaa!

    Grazie !

    come faccio ora a togliere l’avviso “Le impostazioni correnti non
    consentono il downoad” ?

    penso sia un messaggio del tuo browser… cambia le impostazioni…
