Question

subsriber.rb

class Subscriber < ActiveRecord::Base
  validates_confirmation_of :email, :message => "Your emails don't match!"
end

I have this in my rails app. When I create a new record without matching email
Here’s my create action:

def create
  @subscriber = Subscriber.new(params[:subscriber])
  if @subscriber.save
    redirect_to root_path, :notice => "You've been subscribed!"
  else
    render 'new'
  end
end

How do I make the error message show up in the view file? I don’t see anything in the docs saying I need to add something to my views but the message is not showing up.

Answer 1

You actually do need to add something to your view to show the message.

Rails normally does this for you when you create a scaffold, but if you need to do it manually for a field, you need to add something like this to your HTML template:

<%= f.error_messages_for :email_confirmation %>
