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


Model:

class Attend < Interaction
validate :attends_have_to_be_unique

def attends_have_to_be_unique
unless Interaction.where(:user_id => self.user.id, :type =>
‘Attend’).blank?
errors.add(:user_id, “You are already attending this event”)
end
end
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 [""]
