Why is this re-direct not working? - ruby-on-rails

Question

Controller
def subscribe
#mailchimp_list_id = "01d4743206"
#gb = Gibbon::API.new
#email = params[:email]
#gb.lists.subscribe({
:id => #mailchimp_list_id,
:email => #email,
:double_optin => false,
:send_welcome => false
})
redirect_to root_path, notice: "Whats up"
end
View
<%= form_tag('/posts/subscribe', method: "post", id: "subscribe", remote: "true") do%>
<div class="large-18 columns text-right mailer">
<%= email_field(:email, :email, {id: "mailersub", placeholder: "Enter your email"}) %>
</div>
<div class="large-6 columns text-right mailer">
<%= submit_tag("Submit", id: "mailersubmit") %>
</div>
<% end %>
All I really want to happen is for the mailchimp process to be completed and then then it re-directs to a path with a notice. The controller and view is for a mailer list form, upon submit I would like this to occur.
Any assistance would be greatly appreciated, thanks!

Answer 1

remote: true do ajax request, it can not redirect. u have to remove remote: true OR at js .on ajax:success do location.url = '/'

Answer 2

Here is your answer, you have to render js inside the controller and inline javascript can be used to redirection:
def subscribe
#mailchimp_list_id = "01d4743206"
#gb = Gibbon::API.new
#email = params[:email]
#gb.lists.subscribe({
:id => #mailchimp_list_id,
:email => #email,
:double_optin => false,
:send_welcome => false
})
flash[:notice] = "Whats up"
respond_to do |format|
format.js { render :js => "/" }
end
end
