Rails error_messages helper

Question

This is a very common piece of code

<% form_for :blah... do |f| %>
<%= f.error_messages %>
First name: <%= f.text_field :first_name %><br />
....
<% end %>

error_messages is a helper method but I am having a hard time finding the documentation for it, why is that?

Answer 1

I found them here: error_messages have same params as error_messages_for.

In Rails 3 however, error_messages and error_messages_for have been deprecated and have been moved out to a plugin.
