Rails 3 Javascript Not Executed Despite A Text/javascript Content-type In Response

I am performing an non-ajax GET request on a page. In the corresponding controller/action, I am returning javascript. However, this javascript is not being executed. Rather, it is

Solution 1:

If you want to achieve what you stated in the comments: "User wants to go to page Y from page X, but there's an error." The standard way to do this is set the flash[:error] hash to your message, and redirect back to the referring page. In your layout you'd have some erb snippet like:

<% if flash[:error %>
  <div class='flash error'><%= flash[:error] %></div>
<% end %>

And on your controller you'd set up a before filter like:

before_filter :validate_user

def before_filter
  if <some condition is not met>
    flash[:error] = "Oops...you are not logged in"
    redirect_to :back   # or some_defined_path
  end
end
