First what relationships have you got between the models (has_many, belongs_to or whatever)? As I said last time, if user has_many business_admins then @user.business_admins will always (effectively) be an array, which may be empty. It will never be nil. By the way, you sent your last email to me instead of to the list. Please make sure you reply to the list.
