When your controller action respond with json, how to get action_name.js.erb to redirect to another page?

My controller action perform_review is responding with json. As long as there are an order to fetch, a view partial is re-rendered by perform_review.js.erb with the new order, but when we are out of orders to review, perform_review.js.erb should redirect to an other page.

The controller looks like this:

## orders_controller.rb

class OrdersController < ApplicationController

  def perform_review

    ...

    @order = get_order

    respond_to do |format|
      format.html {
      redirect_to orders_path(current_user)
      }
      format.js {
        if @order == nil
          @redirect_path = orders_path
          return
        end
      }
    end
  end
end

And here is the js.erb file:

## perform_review.js.erb

if ("<%=@redirect_path %>" != "") {
  location.href = "<%=@redirect_path %>";
}
else
  var order_options_partial = $("#order_options_partial");
  order_options_partial.children().remove();
  order_options_partial.append('<%= j render("order_options") %>');

The else part works just fine, but the if part does not. The curious thing is that everything is OK in the controller, and @redirect_path gets assigned with "/orders". However, it looks like perform_review.js.erb does not get triggered after this. To be sure of this I have tried to put in a line that said console.log("Starting perform_review.js.erb");, but it does not get called in the browser console...

You can do it in controller as well

class OrdersController < ApplicationController

  def perform_review

    ...

    @order = get_order

    respond_to do |format|
      format.html {
      redirect_to orders_path(current_user)
      }
      format.js {render :js => "window.location.href = '"+orders_path(current_user)+"'"} if @order.blank?
    end
  end
end

In this way you do not need the if else in your perform_review.js.erb. And if you want to do in the view file, then here is the following code.

<% if (@order.blank?) %>
  window.location.href = "<%= escape_javascript(@redirect_path) %>";
<% else %>
  // your code
<% end %>
