[Html-widget] Rails-like form helpers - RFC for a new module

[Zbigniew Lukasiak]

Hi,

I think the easiest way to start with this would be to try InstantCRUD
to generated the config.

I need to check if it is compatible with schema names composed of 3
parts (Schema::Db::Genders) I only checked it with 2 part names (like
DBSchema::Genders).

But see inline for comments:

my $schema = $c->model('db');
I need the schema not the ResultSet.  But now I think than perhaps I
should change that - your way seems a bit more intuitive.

The config is a list of hashes.

} {

I assume here starts the next field

$conf, $schema, 'Members', $member )

It needs the class (the item is optional so I cannot deduce the class
from it) - it is needed to get values for Selects.

I make a mental note to change 'Tag' to some variable there.
