How to add link to marker using gmaps4rails gem - ruby-on-rails

Question

I would like to add a marker with link in marker, so, when i click that marker, i will redirect to another page
Is anybody know to do it?
Thanks
I already added my code like this :
In controller:
#json = #businesses.results.to_gmaps4rails do |object|
"\"link\": \"#{root_url}\""
end
In view :
<%= gmaps4rails(#json) %>
<% content_for :scripts do %>
<script type="text/javascript">
function redirect_to(url) {
window.location = url;
};
Gmaps4Rails.callback = function() {
function say_yo(arg) { return function(){alert('yo '+ arg + '!' );};};
for (var i = 0; i < Gmaps4Rails.markers.length; ++i) {
google.maps.event.addListener(Gmaps4Rails.markers[i].google_object, 'click', redirect_to(Gmaps4Rails.markers[i].link));
}
}
</script>
<% end %>
Is it any wrong? because there just an info window that show after i clicked the marker(Not redirect to any page)

First include the link inside the json:
Model.all.to_gmaps4rails do |object|
"\"link\": \"your link as string\""
end
Then add the extra listeners in your view (beware to include this AFTER your call to the gmaps method):
<%= gmaps(whatever you need here) %>
<% content_for :scripts do %>
<script type="text/javascript">
function redirect_to(url) {
window.location = url;
};
Gmaps4Rails.callback = function() {
function say_yo(arg) { return function(){alert('yo '+ arg + '!' );};};
for (var i = 0; i < Gmaps4Rails.markers.length; ++i) {
google.maps.event.addListener(Gmaps4Rails.markers[i].google_object, 'click', redirect_to(Gmaps4Rails.markers[i].link));
}
}
</script>
<% end %>
