Rails console shows view is rendered, but doesn

This seems very weird. I have a link that I want to make an ajax call to the controller to delete a users' responses, then redirect to another page. Here's the code for the link:

<%= link_to 'try again', reset_score_path, remote: true, controller: "pages", 
action: "reset_score", class: "btn btn-primary tryAgain", data: { confirm: 'This 
will reset your score to <strong>zero</strong> and reset all of your answers so you 
can start fresh. Do you want to continue?', commit: "Restart", cancel: "No Thanks",
focus: 'none'}, title: "Try Again?" %>

And here's the controller action:

def reset_score
  current_user.responses.destroy_all
  current_user.certificate.destroy
  redirect_to action: "course_page1", format: "html" and return
end

But the problem is that nothing happens in the browser; it doesn't redirect. But the console shows that it is processing and rendering the view. See console output:

Started GET "/pages/reset_score" for 127.0.0.1 at 2014-10-17 07:19:45 -0500

So it appears to show that the view is rendered. However the browser does not actually show this view - it just stays on the previous page.

Any ideas? I'm stumped!

(yes I know AWS is giving an error, but I'm assuming its unrelated to this problem?)

EDIT: Thanks to Pamio's answer, this is the solution code for the controller (replacing line 4 above):

def reset_score
    current_user.responses.destroy_all
    current_user.certificate.destroy

    respond_to do |format|
        format.js { render :js => "window.location.href = '#{pages_course_page1_path}'" }
    end
end

回答1:

You have used redirect_to action: "course_page1", format: "html" and return which is not right. Redirection will work fine if it was an html request but not ajax. So if you want to redirect despite the fact that the request was an ajax, use may something like this

format.js { render :js => "window.location.href = '#{course_page_path}'" }

Or remove the remote: true attribute from the link so it would work just fine.

Hope that helps

回答2:

of course, because you are using ajax, not standard call. If you want to be redirected, try to remove remote: true from link_to. Or if you want to keep using ajax, you need by jQuery do redirection from js file. In your example it should be in reset_score.js.erb
