I have the following models:
Product: name, shop_id (foreign key)
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,
<label for="new_shop">New shop:</label>
<input id="new_shop" name="new_shop" type="text" />
(This "div" is hidden by default with "display: none".)
How should I add this "div" in the Rails form creation ?
<%= 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 <object> to use.
