I have three fields\_for inside a form\_tag.

[http://pastie.org/218918](http://pastie.org/218918)

Two of them, correspond to the same model, :customer, (the two  
objects, billing\_customer and shipping\_customer have been built in the  
controller method). When I submit the form, the parameters only  
include one of the two fields\_for methods and it comes through as the  
model name, not the object name:

“customer”=\>{…}

I know there is a way to use two fields\_for sections that correspond  
to the same model… what am I doing wrong here?

Nik can you update mentioned URL with field names as well

try using following:  
\<% fields\_for :shipping\_customer do |sc| %\>  
\<%= sc.text\_field%\>  
\<% end %\>

```
    <% fields_for :billing do |bi| %>

```

…\<%= b.text\_field%\>  
\<% end %\>

\<% fields\_for :billing\_customer do |bc| %\>  
…\<%= bc.text\_field%\>  
\<% end %\>

MOdel:

ShippingCustomer.new(params[:shipping\_customer])  
Billing.new(params[:billing)  
ShippingCustomer.new(params[:billing\_customer)

I am using something like this and it is working for me.

let me know
