get first 3 occurrence of an array

Question

In my rails app I have below code to print some data from database.

<% @di.each do |d| %>
  <% if d["visibility_team"] == 'for_all' %>
   //my code goes here
  <% end %>
<% end %>

I just want to print first 3 occurrence which fulfill the d["visibility_team"] == 'for_all' condition.

How can I do this?

If you can't get @di as 3 records from DB, how about keeping counter how many ds were printed?

Something like this (feel free to style it the way you want)

<% counter = 0 %>
<% @di.each do |d| %>
  <% if d["visibility_team"] == 'for_all' %>
     <% counter += 1 %>
     <% break if counter == 3 %>
   //your code goes here
  <% end %>
<% end %>

However it's usually a bad taste to have so much logic in views.
