满足条件时跳过特定字段的验证

Question

您好，我在尝试执行以下操作时遇到了麻烦。

我正在制作结帐页面，我有这样的表格

  <%= form_for([@ofert, @order], builder: FoundationFormBuilder) do |f| %>

    <%= f.fields_for :invoice_address do |builder| %>
        <%= render partial: 'invoice_address_fields', locals: { f: builder } %>
    <% end %>

    <%= f.check_box :invoice_equals_shipping, checked: true, label: 'My Invoice address is the same Shipping address' %>

    <%= f.fields_for :shipping_address do |builder| %>
      <%= render partial: 'shipping_address_fields', locals: { f: builder } %>
    <% end %>

    .....
    <% end %>

默认选中“我的发票地址与发货地址相同”复选框，默认情况下使用 jquery 隐藏“发货地址”字段。

这两个字段一开始都是空的，所以用户通常会填写 invoice_address 字段并勾选“我的发票地址是相同的送货地址”复选框，问题是隐藏字段“shipping_address”是验证“字段不能为空”

如何验证选中复选框时不验证字段？

您可以在模型中向validates 添加条件。比如：

validates :shipping_address, presence: true, unless: :invoice_equals_shipping?
