How to run each loop on single item?

Question

I'm pulling all associated objects of a particular object, and doing an each_with_index on it.

ie. subscription.transactions.each_with_index

But when there is only one transaction (and thus it's not an array), I get an undefined method 'each' error.

How do I get around this and basically just run the each once?
