Question

I have this code:

<% if  @states.count > 0 %>  # @states is an active record collection

I just feel like there should be a better way to write this.

I am looking for something like:

<% if  @states.not_empty? %>

I realize this is tiny change but it would be a welcome cleanup.

You probably want ActiveRecord’s any?

http://api.rubyonrails.org/classes/ActiveRecord/Relation.html#method-i-any-3F

<% if @states.any? %>
    Do stuff here if @states has at least one result
<% end %>
