我有订单,它总是有两个地址:发票地址和送货地址。在视图中,我有一个表单,您可以在其中输入两个地址。从我的控制器传递实例 @order ,已经构建了两个地址的子实例。
从我的OrdersConntroller中提取:
def new
@order = Order.new(orderCreationDate: Time.now)
2.times{ @order.addresses.build }
end
在视图中,我如何才能访问第一个@ order.addresses,然后在其他地方访问第二个@ order.addresses?
到目前为止我已尝试过:
<%= form_for @order do |f| %>
...
<%= f.fields_for :addresses do |ff| %>
<%= ff.text_field :firstName %>
...
<% end %>
<% end %>
但是HTML结果如下(名称和id不正确)。
<input type="text" name="order[a][firstName]" id="order_a_firstName">
从我的订单模型中提取:
has_many :addresses, foreign_key: "orderID"
accepts_nested_attributes_for :addresses, allow_destroy: true
支持Thx。

您需要创建两个模型1)InvoiceAddress和2)ShippingAddress
class InvoiceAddress < ActiveRecord::Base
self.table_name = :address
end
class ShippingAddress < ActiveRecord::Base
self.table_name = :address
end
并按顺序模型使用关联
has_one :invoice_address
has_one :shipping_address
和orders_controller.rb
def new
@order = Order.new(orderCreationDate: Time.now)
@invoice_address = @order.build_invoice_address
@shipping_address = @order.build_shipping_address
end
表格将
<%= form_for @order do |f| %>
...
<%= f.fields_for :invoice_address, @invoice_address do |ff| %>
<%= ff.text_field :firstName %>
...
<% end %>
<%= f.fields_for :shipping_address, @shipping_address do |ff| %>
<%= ff.text_field :firstName %>
...
<% end %>
<% end %>
