error_messages_for doesn't work

I'm having a problem, 'cause I wrote the following line in my model
"Hi":

[code]
validates_numericality_of :phone, :only_integer => true, :allow_blank =>
false, :message => "must be a number"
[/code]

And in my "new" view, I put:

[code]
<%= error_messages_for :oi,
                    :header_message => "Erro ao cadastrar usuário." ,
                    :message => "Cheque o(s) seguinte(s) campo(s):"%>
[/code]

Rails notice the error, because I can't save a Hi object with phone not
being a number; but it doesn't show me the errors that was find.

What it should be?

Thanks for any help.

I think that should be hi not oi, and I think you have to put the
model name in quotes also, so
error_messages_for 'hi', .....

Yeah, I'm sorry.

Actually, I wrote it wrong here, in the forum.

It's:

[code]
<%= error_messages_for :hi,
                    :header_message => "Error." ,
                    :message => "Check the following camps:"%>
[/code]

What's in your controller ?

Fred

this tag "[code]" and "[/code]" is just to let everyone know where
begins and where ends my code.
It's not in my controller...

The docs at http://api.rubyonrails.org/classes/ActionView/Helpers/ActiveRecordHelper.html#M002221
show the name in quotes, as I suggested in my previous post. So
error_messages_for 'hi', ...
have you tried that?

Colin

I try to put in quotes, but it also doesn't works...

Can you paste the content that it renders? Also, does anything scroll by
in your server window when you try this?

Additionally, wanted to mention that error_messages_for was removed from
Rails 3, though available as a plugin. So maybe consider just going with
a custom solution now. Here is an snippet that I've used, though note it
is in HAML, not ERB.

# views/shared/_error_messages.html.haml

- if target.errors.any?
  #errorExplanation
    %h2= "#{pluralize(target.errors.count, 'error')} prohibited this
record from being saved:"
    %ul
      - target.errors.full_messages.each do |message|
        %li= message

Then used with

# views/thingy/_form.html.haml

#errors= render 'shared/error_messages', :target => @company

You get a bit more control over what is going on here and are protected
against the imminent removal of the helper.
