How to create a better flash error message

Currently, my flash message looks like this: "Attend was not created. {:user_id=>["You are already attending this event"]}"

How can i make it return: "Attend was not created. You are already attending this event"

Controller / def create:

     if @attend.save        ...      else        format.js { flash[:notice] = "Attend was not created. #{@attend.errors}" }      end

The closest I've gotten to was:

format.js { flash[:notice] = "Attend was not created. #{@attend.errors[:user_id]}" }

which returns: Attend was not created. ["You are already attending this event"]

Would be good, without the [""]
