Question

我正处于一个合乎逻辑的“岔路口”，用户可以选择我的服务付款计划或使用他们预先购买的“优惠券代码”。我有选择“付款计划”工作的功能，现在我正在研究另一个叉子，但我觉得我错了。我最终复制并调整了“付款计划”功能，并包含coupon_code ...所以，如果他们选择使用优惠券以及单独的视图和控制器方法，我会有一条单独的路线。

最后，我需要为将来的付款创建一个“客户”，而不是我创建“客户”并立即收取费用的功能，因此需要在路上使用叉子（我想）。

当然，我可以解决这个问题，所以如果有更好的方法，请告诉我。

这是我试图获得优惠券代码的工作，但是，它不会重定向到新视图，即使日志说它是，“POST”似乎工作正常。我不确定为什么日志显示它正在尝试渲染packages/show.json.jbuilder，我认为这是问题所在：

配置/ routes.rb中

 match '/packages/coupon', to: 'packages#coupon', via: [:post, :get]

Answer 1

如果要异步调用，可以使用 remote: true

<%= form_tag('/packages/coupon', id: 'coupon_form', remote: true) do %>

要获取它，请在 / packages 文件夹 /create.js.erb 文件中创建文件。

console.log("<%= j render @package %>");

检查浏览器控制台以查看提取的数据。

$('nav').after("<div class='alert alert-success'> Package Successfully Added </div>");
$('#packages').append("<%= j render @package %>");

Rails redirect_to不呈现
