Subject: can this be more succinct?

How can this be more succinct? Can I somehow put the nil check inline
with the each?

unless(params[:categories].nil?)
            params[:categories].each do |id|
                @subscriber.subscriptions.create :category_id =>
id, :timestamp_start => Time.now.to_s, :is_subscribed => true
            end
        end
