validation custom message for rails 3

Question

Rails has introduced new way to validate attributes inside model. When I use

validates :title, :presence => true 

it works but when I try to add a custom message

validates :title, :presence => true,:message => "Story title is required" 

an error is generated

Unknown validator: 'message' 

Answer 1

Try this

validates :title, presence: { message: "Story title is required" } 

Answer 2

Actually, I did this in a better way. If you want to remove the field title from the message you should use this on your _form.htmk.erb view:

As you can see inside this view:

<ul>   <% @article.errors.full_messages.each do |msg| %>   <li><%= msg %></li>   <% end %> </ul> 

Replace it by:

<ul>   <% @article.errors.each_with_index do |msg, i| %>   <li><%= msg[1] %></li>   <% end %> </ul>
