@ -365,17 +365,6 @@ You can write this view in Rails 2.3:
|
||||
<% end %>
|
||||
</erb>
|
||||
|
||||
When nesting across a +has_one+ relationship you will need to create a new blank object for the nested object before calling +fields_for+ in the view.
|
||||
|
||||
A +build_<model_name>+ method has been created for this purpose:
|
||||
|
||||
<erb>
|
||||
<% @customer.build_order unless @customer.order %>
|
||||
<% customer_form.fields_for :orders do |order_form| %>
|
||||
</erb>
|
||||
|
||||
Otherwise +@customer.order+ will return +nil+ and your form will fail. +has_many+ relationships do not require this extra step.
