如何在 Rails 中将一个模型的内容分配给另一个模型？
我有以下创建操作：
def create
@order = Order.new(params[:order])
if params[:same_as_above] == "1"
@order.billing_address.name = @order.shipping_address.name
@order.billing_address.number = @order.shipping_address.number
@order.billing_address.street = @order.shipping_address.town
end
if @order.save
if @order.purchase
render :action => "success"
else
render :action => "failure"
end
else
render :action => 'new'
end
end
它有效，但在我将送货地址逐个属性复制到帐单地址的方式中似乎有点麻烦和脆弱。请问有更好的办法吗？
I have the following create action:
def create
@order = Order.new(params[:order])
if params[:same_as_above] == "1"
@order.billing_address.name = @order.shipping_address.name
@order.billing_address.number = @order.shipping_address.number
@order.billing_address.street = @order.shipping_address.town
end
if @order.save
if @order.purchase
render :action => "success"
else
render :action => "failure"
end
else
render :action => 'new'
end
end
It works, but seems a bit cumbersome and brittle in the way i copy the shipping address to the billing address, attribute by attribute. Is there a better way please?
