What, exactly, do you mean by "register" ?

The most direct way is to forget Rails and use HTML with or without ActionView::Helpers::FormTagHelper.

There is also the nested form setup, but your objects will need a common parent. Can you sketch out your use-case, including any related models? There may be a simple solution that your question doesn't trigger in those of us who have read it.

Try to describe it more clearly.

Let me give you an example scenario:

Model is user. Where you want to register multiple users in same form. Simple RHTML/HTML to display form and button to clone the form below. You can regenerate same html with javascript and name the text_field with index like this
HTML
<div id='user_wrapper'>
<%= text_field_tag "user[0][name]" %>.
</div>

Each time you clone the form increase index+1 in your javascript function. When you submit a form you will receive hash with all users details.

js function would be like
function clone_form(){
var count = parseInt($('count').value);
count = count+1;
$('count').value = count;
var fields = '<div id='user_wrapper'>
<input type="text" id= "user_'+count+'_name" name="user['+count+'][name]"
</div> '
$('user_wrapper').insert(fields);
}

Hope this will help?
