Maybe not the most descriptive subject! :-) I have a filter that redirects the user to a login page if they have not logged in on certain pages. Now what is the best way to get the page they where initially requesting and then send the user to that page after they have successfully logged in?

You can do: redirect_to :back From the manual: ":back: Back to the page that issued the request. Useful for forms that are triggered from multiple places. Short-hand for redirect_to (request.env["HTTP_REFERER"])" Rob
PS: However, that only works if you have the login form embedded in your pages. If you have an link that takes the user to a intermediary login form, then the solution I proposed doesn''t work. There''s probably another way to do it then, but I don''t know about it. Rob

Re: Best Way To Get Where You Have Been
Save it in the session before you redirect...
session[:where_you_wanted_to_go] = request.parameters
# Then redirect to login
redirect_to (:controller => "login", :action =>
"login")
The code below goes in your login controller and executes once login is
successful:
where_you_wanted_to_go = session[:where_you_wanted_to_go] || {:action =>
"default_page"}
session[:where_you_wanted_to_go] = nil
redirect_to(where_you_wanted_to_go)
I may not have this 100%, I''m pulling it from memory, I believe I saw
it
covered in the Agile Rails Development book...
Hope this helps,

Most off the login systems spawned from the original login generator include two methods which try to handle this: store_location and redirect_back_or_default - you can look at the login generator, salted hash login generate, login engine and acts_as_authenticated generator/plugin for examples of these methods to copy, and how to use them in your own application. - james On 11/13/05, ryan-efiCBTuagYofEnXWrtFoVw@public.gmane.org <ryan-efiCBTuagYofEnXWrtFoVw@public.gmane.org> wrote:> Save it in the session before you redirect... > > session[:where_you_wanted_to_go] = request.parameters > # Then redirect to login > redirect_to (:controller => "login", :action => "login") > > The code below goes in your login controller and executes once login is > successful: > > where_you_wanted_to_go = session[:where_you_wanted_to_go] || {:action => > "default_page"} > session[:where_you_wanted_to_go] = nil > redirect_to(where_you_wanted_to_go) > > I may not have this 100%, I''m pulling it from memory, I believe I saw it > covered in the Agile Rails Development book... > > Hope this helps, > > --Ryan > > ----- Original Message ----- > From: "John Kopanas" <john-O1KSuMybMhqBUy7/sJONFg@public.gmane.org> > To: <rails-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org> > Sent: Sunday, November 13, 2005 5:14 PM > Subject: [Rails] Best Way To Get Where You Have Been > > > > Maybe not the most descriptive subject! :-) > > > > I have a filter that redirects the user to a login page if they have not > > logged in on certain pages.

Here is a link to a blog that helped me solve a similar problem:
http://www.bigbold.com/snippets/tag/rails/2
I took the code from the site and added two minor changes to handle an empty
session and new/create duplication and it works beautifully for me. Just add
the redirect_back to your actions.

Michael

# Store where we are
def store_locations

just take us to the new

@session[''prevpage''] = @session[''thispage'']

@session[''thispage''] = @request.request_uri

Forgot to add this for the application controller:
# Store the current URL so we can redirect back to it if necessary
before_filter :store_locations
