Fehler beim Aktualisieren einer Auswahlbox durch Ajax

Question

Ich versuche, eine Selectbox zu aktualisieren, die von einer anderen Auswahlbox abhängt. Abhängig von der ersten wird es alle Datensätze durchsuchen, die verwandt sind. Sollte funktionieren, das ich bei der Anmeldung am Gerät tue, aber ich erhalte den folgenden Fehler:

Answer 1

die erste Zeile Ihres Fehler Lesen, schien es, das zu sehen, aus Wort-Controller wiederholt:

ActionController::RoutingError (uninitialized constant Usuarios::SessionsControllerController):

dieser Zeile:

<%= select_tag :empresa, options_for_select(@empresas.map{|e|[e.Empresa, e.id]}), :'data-remote' => 'true', :'data-url' => url_for(:controller => 'sessions_controller', :action => 'busqueda_sucursales', format: 'js') %>

ersetzen :controller => 'sessions_controller' mit :controller => 'sessions'

hier die Beispiele Siehe: http://apidock.com/rails/ActionView/RoutingUrlFor/url_for
