It's saying that @payments is a Payment, not an array of them. This
means that your statement:

> @payments =
> Payment.joins(:application_form).where('application_forms.status'
> =>'pending')

is returning a single Payment object. I don't know why it's doing
that -- maybe it's correct behavior in the case of one result, but it
seems to me a one-element array would be "least surprising". As a
workaround you could try immediately after that:

@payments = [@payments] if Payment === @payments

Let us know how that works for you.

Alternately, are you absolutely sure that nothing else is modifying
@payments? Since you have both singular and plural versions, it's
quite plausible that you added an s on some line where you didn't mean
to. Try searching the controller, view, and partials for @payments
and objectively inspecting each occurrence.
