Rails: How to move array iteration from view to helper

Question

I am looping through an array in view, it works, but when I tried to move the code to helper method, it did not work. The problem is I am not able to do <%= %> inside helper. Anybody could let me know how to fix the code?

original view

<% resources.each do |resource| %>
  <span class="label label-primary">
    <%= resource.name %>
  </span>
<% end %>

updated view

<%= print_resource resources%>

resource_helper.rb

def print_resource(resources)
  resources.each do |resource|
    text = resource.name
    clz = 'label label-primary'
    content_tag :span, text,clz
  end
end

@Thorin return like this ["<span class=\"label label-primary\">Update </span>", "<span class=\"label label-primary\">Delete</span>"'] — Bye

Just do like this:

def print_resource(resources)
  html_values = ""
  resources.each do |resource|
    text = resource.name
    clz = 'label label-primary'
    html_values << (content_tag :span, text,clz)
  end
 html_values.html_safe
end
