hi,

Based on the validation done in a model, how can I show errors in a
custom manner , eg. instead of showing like :



2 errors prohibited this textbrand from being saved

There were problems with the following fields:

    * Textbrand already exists
    * Textbrand approved is not numeric.

By using in view :

<%= error_messages_for 'textbrand' %>

How can I show messages like :

There were problems with the following fields:

    * Textbrand

    * Textbrand approved

And in the form next to the textbrand , I want to show 'already exists'.
and next to approve text field, I want to show ' is not numeric'.

Any help is greatly appreciated.

You can't achieve what you want with error_messages_for.

You'll have to build up your own error display using error_messages_on
(note on instead of for).

You'd think this would be a perfect opportunity to use a custom form
builder, but take care:

I asked that question over a month ago and still haven't had a reply,
so you may find yourself on your own if you try the custom form
builder approach.

Neither AWDWR nor Rails Recipes deal with this.

Ciao,
Sheldon.
