检查数组中的所有元素是否具有相同的值

Question

I have an array 'sub_status_arr' which contains a set of values.

If all elements in that array are 52, a button is displayed, else something else is displayed.

I tried the following but it does not seem to work properly. It is only checking if the array contains 51 and ignoring the rest

<%if sub_status_arr.include? 51 || 53 || 54 %>
  display button
<% else %>
  do something else
<% end %>

How do I check if all elements in the array are 52?

Thanks for your suggestions

I would try the all? function:

if sub_status_arr.all? {|ss| ss == 52}
