Question

我想添加取消Braintree订阅的链接。根据braintree参考，我必须使用const Private = (props) => { return ( <main> <h1>Private </h1> <Link href="/"> <a>Home</a> </Link> </main> ); } Private.getInitialProps = async ({ res }) => { // getInitialProps is ejecuted in server side when you refresh the page (first time) // but if you navigate in client side it is ejecuted in client. Server side and client // have a different session for API calls. Is posible to share the session by client // and server side? const response = await request.get('http://someDomain/private'); let body; if (response.status !== 401) { body = await response.json(); } else { if (res) { res.writeHead(302, { Location: '/login' }) res.end() } else { Router.push('/login') } } return {} } export default Private;

为了达到这个目的，我使用以下代码：

视图/帐户/ show.html.erb

Braintree::Subscription.cancel(# here is placed the braintree_subscription_id)

accounts_controller.rb

<%= link_to 'Cancel Subscription', Braintree::Subscription.cancel(@braintree_subscription_id) %>

但是出现错误def show @accounts = Account.find(params[:id]) @braintree_subscription_id = current_store.braintree_subscription_id end

我做错了什么？有什么想法吗？

根据@Pavan代码更新代码后，单击取消订阅时记录。

undefined method to_model for #<Braintree::ErrorResult:0x007fee12083e98>
Did you mean?  to_yaml

您不能将 API方法作为路径提供给link_to。您应为controller#action定义自定义路径，并在方法中执行逻辑。

#routes.rb
get "/cancel_subscription/:subscription_id", to: "accounts#cancel_subscription", as: "cancel_subscription"

让link_to像这样

<%= link_to 'Cancel Subscription', cancel_subscription_path(subscription_id: @braintree_subscription_id) %>

最后在控制器中

def cancel_subscription
  result = Braintree::Subscription.cancel(params[:subscription_id])
  redirect_to "your desired path"
end
