Hi,  
I would like to ask how to override validation functionality in RoR?  
In active\_record\_helper.rb class there is “hardcoded” default html  
generated durning validation.  
If I will use  
{code:ruby}  
validates\_presence\_of :summary, :description  
{code}  
in my model class, there is html generated:  
{code:html}

## 2 errors prohibited this issue from being saved

There were problems with the following fields:

- Summary can't be blank
- Description can't be blank

{code} I would like to change standard functionality and just have validation message next to input field.

What is the best approach to do this?

Best regards,  
Tomek

Hi,

It is me again. What I have done so far…

In the environment.rb I have added lines  
{code:ruby}  
ActionView::Base.field\_error\_proc = Proc.new {|html\_tag, instance|  
%(

#{html\_tag}
)}

ActionView::Base.field\_error\_proc = Proc.new {|html\_tag, instance|  
%(

#{html\_tag}
)}

module ActionView  
module Helpers  
module ActiveRecordHelper  
def error\_messages\_for(object\_name, options = {})

```
  end
end

```

end  
end  
{code}  
It ovverides standard functionality. But unfortunatly I don’t know how  
to exten field\_error\_proc to have full validation message.

Best regards,  
Tomek
