Ordering of messages in error_messages_for

Is there any way to control the ordering of the error messages in the output of error_messages_for()?

I want to make the error messages match the order of the form elements in my form, and although the validates_presence_of directive has these attributes in that order, they still show up in seemingly random order.

Any way to control this?

Thanks, Wes

At the end of the day the errors are stored in a hash and thus with no
guarenteed order. This might be a good time to replace
error_messages_for with code of your own (if you poke inside the
source for it you'll see that it's pretty simple).

Fred,

I already have a custom version of error_messages_for, so yeah, that's cool.

Thx. for the quick response.

I put my error messages right under the fields they are for:

<%= f.username :text_field %> <% if @user.errors['username'] -%> <br /><span class="error"><%= @user.errors['username'] %></span> <% end -%>

I did not like error_messages_for() when I first tried and I've since found most of my clients don't care for it either.

You can do this:

<%= f.text_field :email, :label => "Email Address", :required => true %> <em><%= error_message_on @user, :email %></em>
