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.
#[email protected]}" }
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
