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

```auto
validates_numericality_of :phone, :only_integer => true, :allow_blank =>
false, :message => "must be a number"
```

And in my “new” view, I put:

```auto
 <%= error_messages_for :oi,
                    :header_message => "Erro ao cadastrar usuário." ,
                    :message => "Cheque o(s) seguinte(s) campo(s):"%>
```

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:

```auto
 <%= error_messages_for :hi,
                    :header_message => "Error." ,
                    :message => "Check the following camps:"%>
```

this tag “`" and "`” 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](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?

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.
