How to get an array from a database in Rails3 even when there's only one record?

In Rails3, I have the following line:

@messages = Message.where("recipient_deleted = ?", false).find_by_recipient_id(@user.id)

In my view, I loop through @messages and print out each message, as such:

<% for message in @messages %>
    <%= message.sender_id %>
    <%= message.created_at %>
    <%= message.body %>
<% end %>

This works flawlessly when there are several messages.

The problem is that when I have one message, I get an error thrown at me: undefined methodeach'`

How do I force rails to always return an array of messages even if there's only one message so that each always works?

Thanks!
