Storing URL locations

rubyonrails-talk

I have a friendship system where users can create new friendships from different views. The idea is to redirect them to where they initially requested, accepted, etc... the friendship. To do this, I need to store the URL path from where they are sending the request. Is there a way to save the initial URL (from where the request mas made to the friendships controller). Any light on this?

Thanks for your time,

Elías

I use the following code to redirect them to the page they requested before they logged in. Maybe this will get you on the right path. I put it in the controller under protected.

Protect a page from unauthorized access.

def protect unless logged_in? session[:protected_page] = request.request_uri flash[:notice] = “Please log in first” redirect_to :action => “login” return false end end

Redirect to the previously requested URL (if present).

def redirect_to_forwarding_url if (redirect_url = session[:protected_page]) session[:protected_page] = nil redirect_to redirect_url else redirect_to :action => “index” end end

Hi Sean thanks for the response.

I thought about a solution based on your answer, but I am not happy with it. My solution consisted on having a before_filter on the controllers I know there might be a call to the friendships controller. This before_filter will be used to save the URL. And then, have a before_filter on the application controller where I do this:

if params[:controller] != "friendships"   session[:return_to] = nil end

The thing is that having this before_filter every time for every controller doesn't seems right.

Thanks,
