i want display page user logging in ... a user has login before viewing pages. if not, user redirected login. @ point want display name of page want go , view once logged in. in session controller, under create def - created following instant variable: @intended_url = session::get('url.intended', url('/')); and view page contains following: <h4>sign in go <%= @intended_url %>. unfortunately, nothing showing up? if want store in session, must in controller has access it. means setting session takes place in controller page. by session[:page_name = @intended_id then can retrieve with display ------> session[:page_name] your problem can solved instead calling controller page. controller.controller_action this displays controllers action name if follow ruby on rails design page name.

i'm getting stuck nhibernate @ moment , i'm trying work out how best correctly design repositories whilst correctly managing lifetime of session. from examples i've seen, seems common practise inject isession each of repositories follows: public class somerepository : irepository { private readonly isession _session; public somerepository(isession session) { _session = session; } public ilist<t> loadsomedata() { return _session.query<t>().where(...).tolist(); } } so fine, can see couple of cases there problems: 1) there may not 1 session lifetime of app. 2) when accessing nhibernate should wrap our calls in transaction - if transaction faults must rollback transaction , close session. in both these cases repository defunct references closed session. my particular application long running process, call nhibernate, expect high turnover sessions instead of keeping 1 session open lifetime of app. i th
