Rails - Nov 2007 - Login Redirect - Hacking the session[original_uri]

Hi There,

I have several ajax elements that require authorization, but for various
reasons, they can''t pass session[original_uri] to the redirect on user
log in.  I''m trying to hack in a uri by passing a param to the login
page.

I can see that the param is passing into the login page, but for
whatever reason, no matter what I do, the user is redirected to the
homepage after login.

Would anyone have any ideas?  thanks soo much!

-Mario



#code from show.rhtml
if current_user
 #ajax code
else
  link_to "vote up", login_url(:referrer_uri =>
request.request_uri) %>
end

#Controller
  def create

    uri ||= params[:referrer_uri] #pull in hacked original_uri
    uri ||= session[:original_uri] #pull in sessions''s original uri
    uri ||= homepage_url #default to homepage

    render :action => :new and return true if request.get?

    if params[:user_name] and params[:password] and user
User.authenticate(params[:user_name], params[:password])
      session[:user_id] = user.id
      session[:original_uri] = nil
      redirect_to(uri) and return true
    else
      flash[:failure] = "Invalid username or password."
      redirect_to login_url and return false
    end
  end

i''ve used that thing several times, as you want it and it works fine.

seems to me, it didn''t reach the redirect_to(uri) line for some reason 
or uri is not set to the right path in the first lines of your action

check it that way:

add
logger.info "URI: #{uri}"
behind those "uri ||=" lines
and something the like before your redirects. then check in 
development.log, what actually is in those vars and which parts of your 
code are reached.

Thanks for the tip!

That helped me track down my problem.  Apparently, the uri wasn''t 
getting carried over the the create action in my session controller.  So 
I just added the param to my login form.


<% form_tag login_path(:referrer_uri => params[:referrer_uri]), :class 
=> "submit-form login" do %>

lo, you didn''t mention a form, in that case te user had to press the 
''submit'' and your link_to is dead anyway (? i think) :)

your solution is ok, alternately you could pass stuff like that in a 
hidden field
not, that there''s a big difference
