Loop using Ruby within :javascript Haml definition

Question

I have a JSON to declare in :javascript and I am not familiar with Ruby. The JSON is below:

:javascript
  var collections = {
    feed: [{'label': 'All', 'url': 'All', 'isSelected': false}]
  };

But I want the part below in feed variable to repeat 20 times:

{'label': 'All', 'url': 'All', 'isSelected': true}

How do I do that using Ruby in Haml?

Thanks.

Would be helpful if you post some of your code around. You can always use the <% %> and the <%= %> syntax inside haml — 23tux

If you just want to repeat that line as a string, you can do something like this: <%= 20.times { "{'label': 'All', 'url': 'All', 'isSelected': true}" } %>. Not tested, but you should get the point — 23tux

One way:

:javascript
   var collections = {
     feed: [<%="{'label': 'All', 'url': 'All', 'isSelected': false}" * 20 %>]
   };

Another way:

:javascript
  var colections = {
    <%=(["feed: {'label': 'All', 'url': 'All', 'isSelected': false}"] * 20).join(',')%>
  }
