Instead of redirect_to render a partial with a line of JS like this:

Hi daociyiyou ,

Try this:

def find_created_actions     unless @if_login        flash[:login]="..."        redirect_to(:controller=>"login",:action=>"login")     end     if @if_login        @user_cactions=@user.sponsored_actions        render :update do |page|           page.replace_html 'element_id',             :partial => "created_actions", :object => @user_cactions        end     else        render :update do |page|           page.redirect_to(:controller=>"login",:action=>"login")        end     end end

And make sure you're *not* using the :update option on your remote_form. 'page.redirect_to()' will generate javascript similar to Hassan's aforementioned suggestion.

Hi, just a note that this does not work. Because the redirect gets trapped inside the Ajax call. If you use firebug you can see what happens.

So it seems the only way to redirect is to use a javascript redirect as mentioned on:

You're right. There's a confinient helper to generate the right javascript (redirect_to (ActionView::Helpers::PrototypeHelper::JavaScriptGenerator::GeneratorMethods) - APIdock):

def find_created_actions     unless @if_login         render :update do |page|             flash[:login]="..."             page.redirect_to(:controller=>"login",:action=>"login")         end     end     [...] end

Here is a cleaner way. Just put the following code on your application_controller.rb. Now, redirect_to should work with Ajax calls as well as regular requests.

def redirect_to(options = {}, response_status = {})   if request.xhr?     render(:update) {|page| page.redirect_to(options)}   else     super(options, response_status)   end end
