Need help with Rails form creation

Rails
1

I have the following models:

Product: name, shop_id (foreign key)
Shop:    name

The associations are:

Product: belongs_to :shop
Shop:    has_many   :products

In the form that creates a new Product I have:

<%= f.label(:shop, "Shop:") %>
<%= f.select(...) %>

This is a select box with all existing shops. The last option in this
select box is “Create New Shop”. When user clicks this option,
Javascript shows an extra field:

<div id="new_shop_wrapper">
    <label for="new_shop">New shop:</label>
    <input id="new_shop" name="new_shop" type="text" />
</div>

(This “div” is hidden by default with “display: none”.)

How should I add this “div” in the Rails form creation ?

I tried:

<%= f.label(:new_shop, "New Shop:") %>
<%= f.text_field(:new_shop) %>

but it doesn’t work because “new_shop” is not Product’s field.

I thought to use:

<%= text_field(<object>, :new_shop) %>

but I don’t know what to use.

Please advise.

Just put it in as HTML. There’s nothing magical here.
